+<h3>How to Port</h3>
+
+<h4>Basic considerations</h4>
+<p>The FatFs module is assuming following conditions on portability.</p>
+<ul>
+<li>ANSI C<br>
+The FatFs module is a middleware written in ANSI C (C89). There is no platform dependence, so long as the compiler is in compliance with ANSI C.</li>
+<li>Size of integer types<br>
+The FatFs module assumes that size of <tt>char</tt>/<tt>short</tt>/<tt>long</tt> are 8/16/32 bit and <tt>int</tt> is 16 or 32 bit. These correspondence are defined in <tt>integer.h</tt>. This will not be a problem on most compilers. When a conflict with existing definitions is occured, you must resolve it with care.</li>
+</ul>
+
+<h4>System organizations</h4>
+<p>The dependency diagram shown below is a typical but not specific configuration of the embedded system with FatFs module.</p>
+<p><img src="../res/modules.png" width="580" height="280" alt="dependency diagram"></p>
+<p>(a) If a working disk module with FatFs disk interface is provided, nothing else will be needed. (b) To attach existing disk drivers with different interface, glue functions are needed to translate the interfaces between FatFs and the drivers.</p>
+<p><img src="../res/funcs.png" width="750" height="420" alt="functional diagram"></p>
+
+<h4>Required functions</h4>
+<p>You need to provide only low level disk I/O functions required by FatFs module and nothing else. If a working disk module for the target system is already provided, you need to write only glue functions to attach it to the FatFs module. If not, you need to port another disk I/O module or write it from scratch. Most of defined functions are not that always required. For example, any write function is not required at read-only configuration. Following table shows which function is required depends on the configuration options.</p>

+<h3>Long File Name</h3>
+<p>FatFs module supports long file name (LFN). The two different file names, short file name (SFN) and LFN, of a file is transparent on the API except for <tt>f_readdir</tt> function. The support for LFN is disabled by default. To enable the LFN, set <tt><a href="config.html#use_lfn">FF_USE_LFN</a></tt> to 1, 2 or 3, and add <tt>ffunicode.c</tt> to the project. The LFN requiers a certain working buffer in addition. The buffer size can be configured by <tt><a href="config.html#max_lfn">FF_MAX_LFN</a></tt> according to the available memory. The length of an LFN will be up to 255 characters, so that the <tt>FF_MAX_LFN</tt> should be set to 255 for all file names. If the size of working buffer is insufficient for the input file name, the file function fails with <tt>FR_INVALID_NAME</tt>. When use any re-entry to the API with LFN is enabled, <tt>FF_USE_LFN</tt> must be set to 2 or 3. In this case, the file function allocates the working buffer on the stack or heap. The working buffer occupies <tt>(FF_MAX_LFN + 1) * 2</tt> bytes and additional <tt>(FF_MAX_LFN + 44) / 15 * 32</tt> bytes when exFAT is enabled.</p>

+<p>When the LFN is enabled, the module size will be increased depends on the configured code page. Right table shows increment of code size by LFN function at different code pages. Especially, in the CJK region, tens of thousands of characters are being used. Unfortunately, it requires a huge OEM-Unicode bidirectional conversion table and the module size will be drastically increased as shown in the table. As the result, the FatFs with LFN enebled with those code pages will not able to be ported on the most 8-bit MCU systems.</p>
+<p>There ware some restrictions on using LFN for open source project because the support for LFN on the FAT volume was a patent of Microsoft Corporation. The related patents have expired and using the LFN function have got free for any projects.</p>

+
+<div class="para doc" id="unicode">
+<h3>Unicode API</h3>
+<p>By default, FatFs uses ANSI/OEM code set on the API even at LFN configuration. FatFs can also switch the character encoding on the API to Unicode by configuration option <tt><a href="config.html#lfn_unicode">FF_LFN_UNICODE</a></tt>. This means that FatFs supports the full featured LFN specification. The data type <tt>TCHAR</tt> specifies path name strings on the API is an alias of either <tt>char</tt>(ANSI/OEM) or <tt>WCHAR</tt>(UTF-16) depends on that option. For more information, refer to the description in the <a href="filename.html#uni">file name</a>.</p>
+<p>Note that code page setting, <tt><a href="config.html#code_page">FF_CODE_PAGE</a></tt>, has actually no meaning for the path names at the Unicode API. However it still affects code conversion of string I/O functions at <tt><a href="config.html#strf_encode">FF_STRF_ENCODE = 0</a></tt> and backward compatibility with non-LFN systems, so that code page needs to be set properly when it is considered a problem.</p>

+<p>The exFAT (Microsoft's Extended File Allocation Table) filesystem is a succession of the FAT filesystem which has been widely used in embedded systems, consumer devices and portable storage media. It is adopted by SDA (SD Association) as a recommended filesystem for high capacity SD cards larger than 32 GB and they are being shipped with this format, so that the exFAT became one of the standard filesystems for removable media as well as FAT. The exFAT filesystem allows the file size beyond the 4 GB limit what FAT filesystem allows upto and some filesystem overhead, especially cluster allocation delay, are reduced as well. This feature improves the write throughput to the file.</p>
+<p>Note that the exFAT is a patent of Microsoft Corporation. The exFAT function of FatFs is an implementation based on <cite>US. Pat. App. Pub. No. 2009/0164440 A1</cite>. FatFs module can swich the support for exFAT on/off by configuration option, <tt><a href="config.html#fs_exfat">FF_FS_EXFAT</a></tt>. When enable the exFAT on the commercial products, a license by Microsoft will be needed depends on the final destination of the products.</p>
+<p><em>Remark: Enabling exFAT discards ANSI C (C89) compatibility because of need for 64-bit integer type.</em></p>
+</div>
+
+<div class="para doc" id="reentrant">
+<h3>Re-entrancy</h3>
+<p>The file operations to the <em>different volumes</em> each other is always re-entrant regardless of configurations except when LFN is enabled with static working buffer. It can work concurrently without any mutual exclusion.</p>
+<p>The file operations to the <em>same volume</em> is not re-entrant. It can also be configured for thread-safe by option <tt><a href="config.html#fs_reentrant">FF_FS_REENTRANT</a></tt>. In this case, also the OS dependent synchronization object control functions, <tt>ff_cre_syncobj/ff_del_syncobj/ff_req_grant/ff_rel_grant</tt>, need to be added to the project. There are some examples in the <tt>ffsystem.c</tt>. When a file function is called while the volume is being accessed by another task, the file function to the volume will be suspended until that task leaves the file function. If the wait time exceeded a period defined by <tt>FF_TIMEOUT</tt>, the file function will abort with <tt>FR_TIMEOUT</tt>. The timeout function might not be supported on the some RTOSs.</p>
+<p>There is an exception on the re-entrancy for <tt>f_mount/f_mkfs</tt> function. These volume management functions are not re-entrant to the same volume. When use these functions, other tasks need to avoid to access the volume.</p>
+<p>Remarks: This section describes on the re-entrancy of the FatFs module itself. The <tt>FF_FS_REENTRANT</tt> option enables only exclusive use of each filesystem objects and FatFs never prevents to re-enter <tt>disk_*()</tt> functions. Thus the low level disk I/O layer must be always thread-safe when FatFs API is re-entered for different volumes.</p>
+</div>
+
+<div class="para doc" id="dup">
+<h3>Duplicated File Open</h3>
+<p>FatFs module does not support the read/write collision control of duplicated open to a file. The duplicated open is permitted only when each of open method to a file is read mode. The duplicated open with one or more write mode to a file is always prohibited, and also open file must not be renamed or deleted. A violation of these rules can cause data colluption.</p>
+<p>The file lock control can be enabled by <tt><a href="config.html#fs_lock">FF_FS_LOCK</a></tt> option. The value of option defines the number of open objects to manage simultaneously. In this case, if any open, rename or remove that violating the file shareing rule that described above is attempted, the file function will rejected with <tt>FR_LOCKED</tt>. If number of open objects, files and sub-directories, is equal to <tt>FF_FS_LOCK</tt>, an extra <tt>f_open/f_opendir</tt> function will fail with <tt>FR_TOO_MANY_OPEN_FILES</tt>.</p>
+</div>
+
+<div class="para doc" id="fs1">
+<h3>Performance Effective File Access</h3>
+<p>For good read/write throughput on the small embedded systems with limited size of memory, application programmer should consider what process is done in the FatFs module. The file data on the volume is transferred in following sequence by <tt>f_read</tt> function.</p>
+<p>Figure 1. Sector misaligned read (short)<br>
+<img src="../res/f1.png" width="490" height="110" alt="">
+</p>
+<p>Figure 2. Sector misaligned read (long)<br>
+<img src="../res/f2.png" width="490" height="140" alt="">
+</p>
+<p>Figure 3. Fully sector aligned read<br>
+<img src="../res/f3.png" width="490" height="119" alt="">
+</p>
+<p>The file I/O buffer is a sector buffer to read/write a part of data on the sector. The sector buffer is either file private sector buffer on each file object or shared sector buffer in the filesystem object. The buffer configuration option <tt><a href="config.html#fs_tiny">FF_FS_TINY</a></tt> determins which sector buffer is used for the file data transfer. When tiny buffer configuration (1) is selected, data memory consumption is reduced <tt>FF_MAX_SS</tt> bytes each file object. In this case, FatFs module uses only a sector buffer in the filesystem object for file data transfer and FAT/directory access. The disadvantage of the tiny buffer configuration is: the FAT data cached in the sector buffer will be lost by file data transfer and it must be reloaded at every cluster boundary. However it will be suitable for most application from view point of the decent performance and low memory comsumption.</p>
+<p>Figure 1 shows that a partial sector, sector misaligned part of the file, is transferred via the file I/O buffer. At long data transfer shown in Figure 2, middle of transfer data that covers one or more sector is transferred to the application buffer directly. Figure 3 shows that the case of entier transfer data is aligned to the sector boundary. In this case, file I/O buffer is not used. On the direct transfer, the maximum extent of sectors are read with <tt>disk_read</tt> function at a time but the multiple sector transfer is divided at cluster boundary even if it is contiguous.</p>
+<p>Therefore taking effort to sector aligned read/write accesss eliminates buffered data transfer and the read/write performance will be improved. Besides the effect, cached FAT data will not be flushed by file data transfer at the tiny configuration, so that it can achieve same performance as non-tiny configuration with small memory footprint.</p>
+</div>
+
+<div class="para doc" id="fs2">
+<h3>Considerations on Flash Memory Media</h3>
+<p>To maximize the write performance of flash memory media, such as SDC, CFC and U Disk, it must be controlled in consideration of its characteristitcs.</p>
+<h4>Using Mutiple-Sector Write</h4>
+<div class="rset">
+Figure 6. Comparison between Multiple/Single Sector Write<br>
+<img src="../res/f6.png" width="630" height="148" alt="fig.6">
+</div>
+<p>The write throughput of the flash memory media becomes the worst at single sector write transaction. The write throughput increases as the number of sectors per a write transaction as shown in Figure 6. This effect more appers at faster interface speed and the performance ratio often becomes grater than ten. <a href="../res/rwtest2.png">This graph</a> is clearly explaining how fast is multiple block write (W:16K, 32 sectors) than single block write (W:100, 1 sector), and also larger card tends to be slow at single block write. Number of write transactions also affects life time of the flash memory media. When compared at same amount of write data, the single sector write in Figure 6 above wears flash memory media 16 times more than multiple sector write in Figure 6 below. Single sector write is pretty pain for the flash memory media.</p>
+<p>Therefore the application program should write the data in large block as possible. The ideal write chunk size and alighment is size of sector, and size of cluster is the best. Of course all layers between the application and the storage device must have consideration on multiple sector write, however most of open-source memory card drivers lack it. Do not split a multiple sector write request into single sector write transactions or the write throughput gets poor. Note that FatFs module and its sample disk drivers supprt multiple sector read/write operation. </p>
+<h4>Forcing Memory Erase</h4>
+<p>When remove a file with <tt>f_unlink</tt> function, the data clusters occupied by the file are marked 'free' on the FAT. But the data sectors containing the file data are not that applied any process, so that the file data left occupies a part of the flash memory array as 'live block'. If the file data can be erased on removing the file, those data blocks will be turned into the free block pool. This may skip internal block erase operation to the data block on next write operation. As the result the write performance might be improved. FatFs can manage this function by setting <tt><a href="config.html#use_trim">FF_USE_TRIM</a></tt> to 1. Note that this is an expectation of internal process of the storage device and not that always effective. Most applications will not need this function. Also <tt>f_unlink</tt> function can take a time when remove a large file.</p>
+</div>
+
+<div class="para doc" id="critical">
+<h3>Critical Section</h3>
+<p>If a write operation to the FAT volume is interrupted due to an accidental failure, such as sudden blackout, incorrect media removal and unrecoverable disk error, the FAT structure on the volume can be broken. Following images shows the critical section of the FatFs module.</p>
+<div class="lset">
+Figure 4. Long critical section<br>
+<img src="../res/f4.png" width="320" height="436" alt="fig.4">
+</div>
+<div class="lset">
+Figure 5. Minimized critical section<br>
+<img src="../res/f5.png" width="320" height="436" alt="fig.5">
+</div>
+<br class="clr">
+<p>An interruption in the red section can cause a cross link; as a result, the object being changed can be lost. If an interruption in the yellow section is occured, there is one or more possibility listed below.</p>
+<ul>
+<li>The file data being rewrited is collapsed.</li>
+<li>The file being appended returns initial state.</li>
+<li>The file created as new is gone.</li>
+<li>The file created as new or overwritten remains but no content.</li>
+<li>Efficiency of disk use gets worse due to lost clusters.</li>
+</ul>
+<p>Each case does not affect any file not opened in write mode. To minimize risk of data loss, the critical section can be minimized by minimizing the time that file is opened in write mode or using <tt>f_sync</tt> function as shown in Figure 5.</p>

+<p>This option switches the support for long file name (LFN). When enable the LFN, Unicode support functions <tt>ffunicode.c</tt> need to be added to the project. The working buffer for LFN occupies <tt>(FF_MAX_LFN + 1) * 2</tt> bytes and additional <tt>((FF_MAX_LFN + 44) / 15 * 32</tt> bytes when exFAT enabled. When use stack for the working buffer, take care on stack overflow. When use heap memory for the working buffer, memory management functions, <tt>ff_memalloc</tt> and <tt>ff_memfree</tt>, need to be added to the project.</p>

+</table>
+
+<h4 id="max_lfn">FF_MAX_LFN</h4>
+<p>This option defines the size of LFN working buffer from 12 to 255 in unit of character. This option has no effect when LFN is disabled.</p>
+
+<h4 id="lfn_unicode">FF_LFN_UNICODE</h4>
+<p>This option switches character encoding on the API, ANSI/OEM (0) or Unicode in UTF-16 (1). To use Unicode string for the path name, enable LFN and set this option to 1. This option also affects behavior of string I/O functions. When LFN is disabled, this option has no effect. For more information, read <a href="filename.html#uni">here</a>.</p>
+
+<h4 id="strf_encode">FF_STRF_ENCODE</h4>
+<p>When Unicode API is selected by <tt>FF_LFN_UNICODE = 1</tt>, string I/O functions, <tt>f_gets</tt>, <tt>f_putc</tt>, <tt>f_puts</tt> and <tt>f_printf</tt> convert the character encodins in it. This option defines the assumption of character encoding <em>on the file</em> to be read/written via those functions. When Unicode API is not selected, the string functions work without any conversion and this option has no effect.</p>

+<h3>Volume/Drive Configurations</h3>
+
+<h4 id="volumes">FF_VOLUMES</h4>
+<p>This option configures number of volumes (logical drives, from 1 to 10) to be used.</p>
+
+<h4 id="str_volume_id">FF_STR_VOLUME_ID</h4>
+<p>Disable (0) or Enable (1). This option switches the support for string volume ID. When enabled, also pre-defined strings in <tt>FF_VOLUME_STRS</tt> can be used as drive identifier in the path name.</p>
+
+<h4 id="volume_strs">FF_VOLUME_STRS</h4>
+<p>This option defines the drive ID strings for each logical drives. Number of items must not be less than <tt>FF_VOLUMES</tt>. Valid characters for the drive ID string are: A-Z and 0-9.</p>
+
+<h4 id="multi_partition">FF_MULTI_PARTITION</h4>
+<p>Disable (0) or Enable (1). This option switches multi-partition function. By default (0), each logical drive number is bound to the same physical drive number and only a volume in the physical drive is mounted. When enabled, each logical drive is bound to the partition on the physical drive listed in the user defined partition resolution table <tt>VolToPart[]</tt>. Also <tt>f_fdisk</tt> funciton will be available. For more information, read <a href="filename.html#vol">here</a>.</p>
+
+<h4 id="max_ss">FF_MIN_SS, FF_MAX_SS</h4>
+<p>This set of options defines the extent of sector size used on the low level disk I/O interface, <tt>disk_read</tt> and <tt>disk_write</tt> function. Valid values are 512, 1024, 2048 and 4096. <tt>FF_MIN_SS</tt> defines minimum sector size and <tt>FF_MAX_SS</tt> defines the maximum sector size. Always set both 512 for memory card and harddisk. But a larger value may be required for on-board flash memory and some type of optical media. When <tt>FF_MAX_SS &gt; FF_MIN_SS</tt>, support of variable sector size is enabled and <tt>GET_SECTOR_SIZE</tt> command needs to be implemented to the <tt>disk_ioctl</tt> function.</p>
+
+<h4 id="use_trim">FF_USE_TRIM</h4>
+<p>Disable (0) or Enable (1). This option switches ATA-TRIM function. To enable Trim function, also <tt>CTRL_TRIM</tt> command should be implemented to the <tt>disk_ioctl</tt> function.</p>
+
+<h4 id="fs_nofsinfo">FF_FS_NOFSINFO</h4>
+<p>0 to 3. If you need to know correct free space on the FAT32 volume, set bit 0 of this option, and <tt>f_getfree</tt> function at first time after volume mount will force a full FAT scan. Bit 1 controls the use of last allocated cluster number.</p>
+<table class="lst1">
+<tr><th>Value</th><th>Description</th></tr>
+<tr><td>bit0=0</td><td>Use free cluster count in the FSINFO if available.</td></tr>
+<tr><td>bit0=1</td><td>Do not trust free cluster count in the FSINFO.</td></tr>

+<tr><td>bit1=1</td><td>Do not trust last allocated cluster number in the FSINFO.</td></tr>
+</table>
+
+</div>
+
+
+<div class="para doc" id="system">
+<h3>System Configurations</h3>
+
+<h4 id="fs_tiny">FF_FS_TINY</h4>
+<p>Normal (0) or Tiny (1). At the tiny configuration, size of the file object <tt>FIL</tt> is reduced <tt>FF_MAX_SS</tt> bytes. Instead of private data buffer eliminated from the file object, common sector buffer in the filesystem object <tt>FATFS</tt> is used for the file data transfer.</p>
+
+<h4 id="fs_exfat">FF_FS_EXFAT</h4>
+<p>This option switches support for the exFAT filesystem in addition to the FAT/FAT32 filesystem, Enabled(1) or Disabled(0). To enable this feature, also LFN must be enabled and configureing <tt>FF_LFN_UNICODE = 1</tt> and <tt>FF_MAX_LFN = 255</tt> is recommended for full-featured exFAT function. Note that enabling exFAT discards ANSI C (C89) compatibility because of need for 64-bit integer type.</p>
+
+<h4 id="fs_nortc">FF_FS_NORTC</h4>
+<p>Use RTC (0) or Do not use RTC (1). This option controls timestamp function. If the system does not have an RTC function or valid timestamp is not needed, set <tt>FF_FS_NORTC</tt> to 1 to disable the timestamp function. Any object modified by FatFs will have a fixed timestamp defined by <tt>FF_NORTC_MON</tt>, <tt>FF_NORTC_MDAY</tt> and <tt>FF_NORTC_YEAR</tt>. To use the timestamp function, set <tt>FF_FS_NORTC = 0</tt> and add <tt>get_fattime</tt> function to the project to get the current time form real-time clock. This option has no effect at read-only configuration.</p>
+
+<h4 id="nortc_time">FF_NORTC_MON, FF_NORTC_MDAY, FF_NORTC_YEAR</h4>
+<p>This set of options defines the time to be used at no RTC systems. This option has no effect at read-only configuration or <tt>FF_FS_NORTC = 0</tt>.</p>
+
+<h4 id="fs_lock">FF_FS_LOCK</h4>
+<p>This option switches file lock function to control duplicated file open and illegal operations to open objects. Note that the file lock function is independent of re-entrancy. This option must be 0 at read-only configuration.</p>
+<table class="lst1">
+<tr><th>Value</th><th>Description</th></tr>
+<tr><td>0</td><td>Disable file lock function. To avoid collapsing file by wrong file operation, application program needs to avoid illegal open, remove and rename to the open objects.</td></tr>
+<tr><td>&gt;0</td><td>Enable file lock function. The value defines how many files/sub-directories can be opened simultaneously under the file lock control. Illigal operations to the open object will be rejected with <tt>FR_LOCKED</tt>.</td></tr>
+</table>
+
+<h4 id="fs_reentrant">FF_FS_REENTRANT</h4>
+<p>Disable (0) or Enable (1). This option switches the re-entrancy (thread safe) of the FatFs module itself. Note that file/directory access to the different volume is always re-entrant and it can work simultaneously regardless of this option but volume control functions. <tt>f_mount</tt>, <tt>f_mkfs</tt> and <tt>f_fdisk</tt>, are always not re-entrant. Only file/directory access to the same volume, in other words, exclusive use of each filesystem object, is under control of this function. To enable this feature, also user provided synchronization handlers, <tt>ff_req_grant</tt>, <tt>ff_rel_grant</tt>, <tt>ff_del_syncobj</tt> and <tt>ff_cre_syncobj</tt>, need to be added to the project. Sample code is available in <tt>ffsystem.c</tt>.</p>
+
+<h4 id="fs_timeout">FF_FS_TIMEOUT</h4>
+<p>Number of time ticks to abort the file function with <tt>FR_TIMEOUT</tt> when wait time is too long. This option has no effect when <tt>FF_FS_REENTRANT = 0</tt>.</p>
+
+<h4 id="sync_t">FF_SYNC_t</h4>
+<p>This option defines O/S dependent sync object type. e.g. <tt>HANDLE</tt>, <tt>ID</tt>, <tt>OS_EVENT*</tt>, <tt>SemaphoreHandle_t</tt> and etc. A header file for O/S definitions needs to be included somewhere in the scope of <tt>ff.c</tt>. This option has no effect when <tt>FF_FS_REENTRANT = 0</tt>.</p>

+<table class="lst">
+<caption>Standard ioctl command used by FatFs</caption>
+<tr><th>Command</th><th>Description</th></tr>
+<tr><td>CTRL_SYNC</td><td>Make sure that the device has finished pending write process. If the disk I/O module has a write back cache, the dirty buffers must be written back to the media immediately. Nothing to do for this command if each write operation to the media is completed within the <tt>disk_write</tt> function.</td></tr>
+<tr><td>GET_SECTOR_COUNT</td><td>Returns number of available sectors on the drive into the <tt>DWORD</tt> variable pointed by <tt class="arg">buff</tt>. This command is used in only <tt>f_mkfs</tt> and <tt>f_fdisk</tt> function to determine the volume/partition size to be created. Required at <tt>FF_USE_MKFS == 1</tt> or <tt>FF_MULTI_PARTITION == 1</tt>.</td></tr>
+<tr><td>GET_SECTOR_SIZE</td><td>Returns sector size of the device into the <tt>WORD</tt> variable pointed by <tt class="arg">buff</tt>. Valid return values for this command are 512, 1024, 2048 and 4096. This command is required only if <tt>FF_MAX_SS &gt; FF_MIN_SS</tt>. When <tt>FF_MAX_SS == FF_MIN_SS</tt>, this command is never used and the device must work at that sector size.</td></tr>
+<tr><td>GET_BLOCK_SIZE</td><td>Returns erase block size of the flash memory media in unit of sector into the <tt>DWORD</tt> variable pointed by <tt class="arg">buff</tt>. The allowable value is from 1 to 32768 in power of 2. Return 1 if the erase block size is unknown or non flash memory media. This command is used by only <tt>f_mkfs</tt> function and it attempts to align data area on the erase block boundary. Required at <tt>FF_USE_MKFS == 1</tt>.</td></tr>
+<tr><td>CTRL_TRIM</td><td>Informs the device the data on the block of sectors is no longer needed and it can be erased. The sector block is specified by a <tt>DWORD</tt> array {&lt;start sector&gt;, &lt;end sector&gt;} pointed by <tt class="arg">buff</tt>. This is an identical command to Trim of ATA device. Nothing to do for this command if this funcion is not supported or not a flash memory device. FatFs does not check the result code and the file function is not affected even if the sector block was not erased well. This command is called on remove a cluster chain and in the <tt>f_mkfs</tt> function. Required at <tt>FF_USE_TRIM == 1</tt>.</td></tr>
+</table>

+<h4>Description</h4>
+<p>Read/write operation to the generic storage devices, such as memory card, hadddisk and optical disk, is done in unit of block of data bytes called <em>sector</em>. FatFs supports the sector size in range of from 512 to 4096 bytes. When FatFs is configured for fixed sector size (<tt>FF_MIN_SS == MAX_SS</tt>, this is the most case), the read/write function must work at that sector size. When FatFs is configured for variable sector size (<tt>FF_MIN_SS != MAX_SS</tt>), the sector size of medium is inquired with <tt>disk_ioctl</tt> function immediately following <tt>disk_initialize</tt> function.</p>
+<p>The memory address specified by <tt class="arg">buff</tt> is not that always aligned to word boundary because the argument is defined as <tt>BYTE*</tt>. The unaligned read/write request can occure at <a href="appnote.html#fs1">direct transfer</a>. If the bus architecture, especially DMA controller, does not allow unaligned memory access, it should be solved in this function. There are some workarounds described below to avoid this issue.</p>
+<ul>
+<li>Convert word transfer to byte transfer in this function if needed. - Recommended.</li>
+<li>On the <tt>f_read()</tt> calls, avoid long read request that includes a whole of sector. - Any direct transfer never occures.</li>
+<li>On the <tt>f_read(fp, data, btw, bw)</tt> calls, make sure that <tt>(((UINT)data &amp; 3) == (f_tell(fp) &amp; 3))</tt> is true. - Word alignment of <tt class="arg">buff</tt> is guaranteed.</li>
+</ul>
+<p>Generally, a multiple sector read request must not be split into single sector transactions to the storage device, or read throughput gets worse.</p>

+<h4>Description</h4>
+<p>The specified memory address is not that always aligned to word boundary because the argument is defined as <tt>BYTE*</tt>. For more information, refer to the description of <a href="dread.html"><tt>disk_read</tt></a> function.</p>
+<p>Generally, a multiple sector transfer request must not be split into single sector transactions to the storage device, or the write throughput will be drastically decreased.</p>
+<p>FatFs expects delayed write function of the disk control layer. The write operation to the media does not need to be completed at return from this function by what write operation is in progress or data is only stored into the write-back cache. But write data on the <tt class="arg">buff</tt> is invalid after return from this function. The write completion request is done by <tt>CTRL_SYNC</tt> command of <tt><a href="dioctl.html">disk_ioctl</a></tt> function. Therefore, if a delayed write function is implemented, the write throughput of the filesystem will be improved.</p>

+<h4>Description</h4>
+<p>The <tt>f_expand</tt> function prepares or allocates a contiguous data area to the file. When <tt class="arg">opt</tt> is 1, the function allocates a contiguous data area to the file. Unlike expansion of file by <tt>f_lseek</tt> function, the file must be truncated prior to use this function and read/write pointer of the file stays at top of the file after the function. The file content allocated with this function is <em>undefined</em> because no data is written to the file in this process. The function can fail with <tt>FR_DENIED</tt> due to some reasons below.</p>
+<ul>
+<li>No free contiguous space was found.</li>
+<li>Size of the file was not zero.</li>
+<li>The file has been opened in read-only mode.</li>
+<li>Not allowable file size. (&gt;= 4GiB on FAT volume)</li>
+</ul>
+<p>When <tt class="arg">opt</tt> is 0, the function finds a contiguous data area and set it as suggested point for next allocation instead of allocating it to the file. The next cluster allocation is started at top of the contiguous area found by this function. Thus the write file is guaranteed be contiguous and no allocation delay until the size reaches that size at least unless any other changes to the volume is performed.</p>
+<p>The contiguous file would have an advantage at time-critical read/write operations. It eliminates some overheads in the filesystem and the storage media caused by random access due to fragmented file data. Especially FAT access for the contiguous file on the exFAT volume is completely eliminated and storage media will be accessed sequentially.</p>
+<p>Also the contiguous file can be easily accessed directly via low-level disk functions. But this is not recommended in consideration for future compatibility.</p>

+</head>
+
+<body>
+<h1>Path Names on the FatFs</h1>
+
+<div class="para doc" id="nam">
+<h3>Format of the path names</h3>
+<p>The format of path name on the FatFs module is similer to the filename specs of DOS/Windos as follows:</p>
+<pre>[<em>drive#</em>:][/]<em>directory</em>/<em>file</em></pre>
+<p>The FatFs module supports long file name (LFN) and 8.3 format file name (SFN). The LFN can be used when (<tt><a href="config.html#use_lfn">FF_USE_LFN</a> != 0</tt>). The sub directories are separated with a \ or / in the same way as DOS/Windows API. Duplicated separators are skipped and ignored. Only a difference is that the logical drive is specified in a numeral with a colon. When drive prefix is omitted, the drive number is assumed as <em>default drive</em> (drive 0 or current drive).</p>
+<p>Control characters (<tt>'\0'</tt> to <tt>'\x1F'</tt>) are recognized as end of the path name. Leading/embedded spaces in the path name are valid as a part of the name at LFN configuration but the space is recognized as end of the path name at non-LFN configuration. Trailing spaces and dots are ignored at both configurations.</p>
+<p>In default configuration (<tt><a href="config.html#fs_rpath">FF_FS_RPATH</a> == 0</tt>), it does not have a concept of current directory like OS oriented filesystem. Every object on the volume is always specified in full path name that followed from the root directory. Dot directory names (<tt>".", ".."</tt>) are not allowed. Heading separator is ignored and it can be exist or omitted. The default drive is fixed to drive 0.</p>
+<p>When relative path is enabled (<tt>FF_FS_RPATH &gt;= 1</tt>), specified path is followed from the root directory if a heading separator is exist. If not, it is followed from the current directory of the drive set by <a href="chdir.html"><tt>f_chdir</tt></a> function. Dot names are also allowed for the path names. The default drive is the current drive set by <a href="chdrive.html"><tt>f_chdrive</tt></a> function.</p>
+<table class="lst2">
+<tr><td>Path name</td><td>FF_FS_RPATH == 0</td><td>FF_FS_RPATH &gt;= 1</td></tr>
+<tr class="lst3"><td>file.txt</td><td>A file in the root directory of the drive 0</td><td>A file in the current directory of the current drive</td></tr>
+<tr><td>/file.txt</td><td>A file in the root directory of the drive 0</td><td>A file in the root directory of the current drive</td></tr>
+<tr><td></td><td>The root directory of the drive 0</td><td>The current directory of the current drive</td></tr>
+<tr><td>/</td><td>The root directory of the drive 0</td><td>The root directory of the current drive</td></tr>
+<tr><td>2:</td><td>The root directory of the drive 2</td><td>The current directory of the drive 2</td></tr>
+<tr><td>2:/</td><td>The root directory of the drive 2</td><td>The root directory of the drive 2</td></tr>
+<tr><td>2:file.txt</td><td>A file in the root directory of the drive 2</td><td>A file in the current directory of the drive 2</td></tr>
+<tr><td>../file.txt</td><td>Invalid name</td><td>A file in the parent directory</td></tr>
+<tr><td>.</td><td>Invalid name</td><td>This directory</td></tr>
+<tr><td>..</td><td>Invalid name</td><td>Parent directory of the current directory (*)</td></tr>
+<tr><td>dir1/..</td><td>Invalid name</td><td>The current directory</td></tr>
+<tr><td>/..</td><td>Invalid name</td><td>The root directory (sticks the top level)</td></tr>
+</table>
+<p>When option <tt><a href="config.html#str_volume_id">FF_STR_VOLUME_ID</a></tt> is specified, also pre-defined arbitrary keyword instead of a numeral can be used as drive prefix. e.g. <tt>"sdcard:file1.txt"</tt>, <tt>"ram:swapfile.dat"</tt> and DOS/Windows style drive letter, of course.</p>
+<p><em>Remark: In this revision, double dot name <tt>".."</tt> cannot follow the parent directory on the exFAT volume. It will work as <tt>"."</tt> and stay there.</em></p>
+</div>
+
+<div class="para doc" id="case">
+<h3>Legal Characters and Case Sensitivity</h3>
+<p>On the FAT filesystem, legal characters for object name (file/directory name) are, <tt>0-9 A-Z ! # $ % &amp; ' ( ) - @ ^ _ ` { } ~</tt> and extended characters (<tt>\x80</tt>-<tt>\xFF</tt>). Under LFN supported system, also <tt>+ , ; = [ ]</tt> and space are legal for the object name and the white spaces and periods can be placed anywhere in the path name except for end of the object name.</p>
+<p>FAT filesystem is case-insensitive to the object names on the volume. All object names are compared in case-insensitive. For example, these three names, <tt>file.txt</tt>, <tt>File.Txt</tt> and <tt>FILE.TXT</tt>, are identical. This is applied to also extended charactres. When an object is created on the FAT volume, upper converted name is recorded to the SFN entry, and the raw name is recorded to the LFN entry.</p>
+<p>As for the DBCS language MS-DOS, it was case-sensitive to the extended characters. To follow this specification, FatFs works with case-sensitive to the extended characters at only non-LFN with DBCS configuration (DOS/DBCS specs). But at LFN configuration, FatFs works with case-insensitive to all characters (WindowsNT specs). This can cause a problem on compatibility with Windows system when an object with extended characters is created on the volume at non-LFN and DBCS configuration; therfore the object names with DBCS extended characters should not be used on the FAT volume shared by those systems.</p>
+</div>
+
+<div class="para doc" id="uni">
+<h3>Unicode API</h3>
+<p>The path names are input/output in either ANSI/OEM code or Unicode depends on the configuration options. The type of arguments which specify the path names are defined as <tt>TCHAR</tt>. It is an alias of <tt>char</tt> by default. The code set used to the path name string is ANSI/OEM specifid by <tt><a href="config.html#code_page">FF_CODE_PAGE</a></tt>. When <tt><a href="config.html#lfn_unicode">FF_LFN_UNICODE</a></tt> is set to 1, the type of the <tt>TCHAR</tt> is switched to <tt>WCHAR</tt> to support Unicode (UTF-16 encoding). In this case, the full-featured LFN specification is supported and the Unicode specific characters, such as ✝☪✡☸☭, can also be used for the path name. It also affects data types and encoding of the string I/O functions. To define literal strings, <tt>_T(s)</tt> and <tt>_TEXT(s)</tt> macro are available to select either ANSI/OEM or Unicode automatically. The code shown below is an example to define the literal strings.</p>
+<pre>
+ f_open(fp, "filename.txt", FA_READ);      <span class="c">/* ANSI/OEM string */</span>
+ f_open(fp, L"filename.txt", FA_READ);     <span class="c">/* Unicode string */</span>
+ f_open(fp, _T("filename.txt"), FA_READ);  <span class="c">/* Changed by configuration */</span>
+</pre>
+</div>
+
+<div class="para doc" id="vol">
+<h3>Volume Management</h3>
+<p>FatFs module needs dynamic work area, <em>filesystem object</em>, for each volume (logical drive). It is registered/unregistered to the FatFs module by <tt>f_mount</tt> function. By default, each logical drive is bound to the physical drive with the same drive number and an FAT volume on the drive is serched by the volume mount process. It reads boot sectors and checks it if it is an FAT boot sector in order of sector 0 as SFD format, 1st partition, 2nd partition, 3rd partition and 4th partition as FDISK format.</p>
+<p>When <tt><a href="config.html#multi_partition">FF_MULTI_PARTITION</a> == 1</tt> is specified by configuration option, each individual logical drive is bound to the partition on the physical drive specified by volume management table. The volume management table needs to be defined by user to resolve the mappings of logical drives and partitions. Following code is an example of a volume management table.</p>
+<pre>
+Example: 0:-2: are tied to three pri-partitions on the physical drive 0 (fixed drive)
+         3: is tied to an FAT volume on the physical drive 1 (removable drive)
+
+PARTITION VolToPart[FF_VOLUMES] = {
+    {0, 1},     <span class="c">/* "0:" ==> Physical drive 0, 1st partition */</span>
+    {0, 2},     <span class="c">/* "1:" ==> Physical drive 0, 2nd partition */</span>
+    {0, 3},     <span class="c">/* "2:" ==> Physical drive 0, 3rd partition */</span>
+    {1, 0}      <span class="c">/* "3:" ==> Physical drive 1, auto detection */</span>
+};
+</pre>
+<div><img src="../res/f7.png" width="900" height="288" alt="relationship between logical drive and physical drive"></div>
+<p>There are some considerations on using multi-partition configuration.</p>
+<ul>
+<li>The physical drive that has two or more mounted partitions must be non-removable. Media change while a system operation is prohibited.</li>
+<li>Only four primary partitions can be specified. Extended partition is not supported.</li>
+<li>Windows does not support multiple volumes on the removable storage. Only first parition will be recognized.</li>

+<h4>Description</h4>
+<p>File read/write ponter in the open file object points the data byte to be read/written at next read/write operation. It advances as the number of bytes read/written. The <tt>f_lseek</tt> function moves the file read/write pointer without any read/write operation to the file.</p>
+<p>When an offset beyond the file size is specified at write mode, the file size is expanded to the specified offset. The file data in the expanded area is <em>undefined</em> because no data is written to the file in this process. This is suitable to pre-allocate a data area to the file quickly for fast write operation. When a contiguous data area needs to be allocated to the file, use <tt>f_expand</tt> function instead. After the <tt>f_lseek</tt> function succeeded, the current read/write pointer should be checked in order to make sure the read/write pointer has been moved correctry. In case of the read/write pointer is not the expected value, either of followings has been occured.</p>
+<ul>
+<li>End of file. The specified <tt class="arg">ofs</tt> was clipped at end of the file because the file has been opened in read-only mode.</li>
+<li>Disk full. There is no free space on the volume to expand the file.</li>
+</ul>
+<p>The fast seek function enables fast backward/long seek operations without FAT access by using an on-memory CLMT (cluster link map table). It is applied to <tt>f_read</tt> and <tt>f_write</tt> function as well, however, the file size cannot be expanded by <tt>f_write</tt>, <tt>f_lseek</tt> function while the file is in fast seek mode.</p>
+<p>The fast seek function is enabled when the member <tt>cltbl</tt> in the file object is not NULL. The CLMT must be created into the <tt>DWORD</tt> array prior to use the fast seek function. To create the CLMT, set address of the <tt>DWORD</tt> array to the member <tt>cltbl</tt> in the open file object, set the size of array in unit of items to the first item and call the <tt>f_lseek</tt> function with <tt class="arg">ofs</tt><tt> = CREATE_LINKMAP</tt>. After the function succeeded and CLMT is created, no FAT access is occured in subsequent <tt>f_read</tt>, <tt>f_write</tt>, <tt>f_lseek</tt> function to the file. The number of items used or required is returned into the first item of the array. The number of items to be used is (number of the file fragments + 1) * 2. For example, when the file is fragmented in 5, 12 items in the array will be used. If the function failed with <tt>FR_NOT_ENOUGH_CORE</tt>, the given array size is insufficient for the file.</p>

+<h4>Description</h4>
+<p>The FAT sub-type, FAT12/FAT16/FAT32, of FAT volume except exFAT is determined by only number of clusters on the volume and nothing else, according to the FAT specification issued by Microsoft. Thus which FAT sub-type is selected, is depends on the volume size and the specified cluster size. In case of the combination of FAT type and cluter size specified by argument cannot be valid on the volume, the function will fail with <tt>FR_MKFS_ABORTED</tt>.</p>
+<p>The allocation unit, also called <em>cluster</em>, is a unit of disk space allocation for files. When the size of allocation unit is 32768 bytes, a file with 100 bytes in size occupies 32768 bytes of disk space. The space efficiency of disk usage gets worse as increasing size of allocation unit, but, on the other hand, the read/write performance increases as the size of allocation unit. Therefore the size of allocation unit is a trade-off between space efficiency and performance. For the large storages in GB order, 32768 bytes or larger (this is automatically selected by default) is recommended for most case unless extremely many small files are created on a volume.</p>
+<p>There are two disk formats, FDISK and SFD. The FDISK format is usually used for harddisk, MMC, SDC, CFC and U Disk. It can divide a physical drive into one or more partitions with a partition table on the MBR (maser boot record, the first sector of the physical drive). The SFD (super-floppy disk) format is non-partitioned disk format. The FAT volume starts at the first sector of the physical drive without any disk partitioning. It is usually used for floppy disk, Microdrive, optical disk and most type of super-floppy media. Some systems support only either one of the two formats and the other is not supported.</p>
+<p>When the logical drive to be formatted is bound to a physical drive and <tt>FM_SFD</tt> is not specified, a primary partition occupies whole drive space is created and then the FAT volume is created in it. When <tt>FM_SFD</tt> is specified, the FAT volume occupies from the first sector of the physical drive is created without partitioning.</p>
+<p>When the logical drive to be formatted is bound to a specific partition (1-4) by support of multiple partition (<tt><a href="config.html#multi_partition">FF_MULTI_PARTITION</a></tt>) the FAT volume is created into the partition and <tt>FM_SFD</tt> flag is ignored. The physical drive needs to be partitioned with <tt>f_fdisk</tt> function or any other partitioning tools prior to create the FAT volume with this function.</p>

+<h4>Description</h4>
+<p>FatFs needs work area (<em>filesystem object</em>) for each logical drives (FAT volumes). Prior to perform file/directory operations, a filesystem object needs to be registered with <tt>f_mount</tt> function to the logical drive. The file/directory API functions get ready to work after this procedure. If there is any open object of file or directory on the logical drive, the object will be invalidated by this function.</p>
+<p>The <tt>f_mount</tt> function registers/unregisters a filesystem object to the FatFs module as follows:</p>
+<ol>
+<li>Determines the logical drive which specified by <tt class="arg">path</tt>.</li>
+<li>Clears and unregisters the regsitered work area of the volume if exist.</li>
+<li>Clears and registers the new work area to the volume if <tt class="arg">fs</tt> is not NULL.</li>
+<li>Performs volume mount process to the volume if forced mounting is specified.</li>
+</ol>
+<p>If forced mounting is not specified (<tt>opt = 0</tt>), this function always succeeds regardless of the physical drive status. It only clears (de-initializes) the given work area and registers its address to the internal table and no activity of the physical drive in this function. To unregister the work area, specify a NULL to the <tt class="arg">fs</tt>, and then the work area can be discarded. The volume mount processes, initialize the corresponding physical drive, find the FAT volume in it and then initialize the work area, is performed in the subsequent file/directory functions when either of following conditions is true.</p>
+<ul>
+<li>File system object has not been initialized. It is de-initialized by <tt>f_mount</tt> function.</li>
+<li>Physical drive is not initialized. It is de-initialized by system reset or media removal.</li>
+</ul>
+<p>If the function with forced mounting (<tt>opt = 1</tt>) failed, it means that the filesystem object has been registered successfully but the volume is currently not ready to work. The volume mount process will be attempted at subsequent file/directroy functions if the filesystem object is not initialized. (delayed mounting)</p>
+<p>If implementation of the disk I/O layer lacks asynchronous media change detection, application program needs to perform <tt>f_mount</tt> function after each media change to force cleared the filesystem object.</p>

For more information, refer to <a href="appnote.html#critical">application note</a>.</p>
+<p>However there is no sense in <tt>f_sync</tt> function immediataly before <tt>f_close</tt> function because it performs <tt>f_sync</tt> function in it. In other words, the differnce between those functions is that the file object is invalidated or not.</p>
