<h2>File and Path name on the FatFs module</h2>
|
|
|
|
<div class="para">
|
|
<p>The format of file and path name on the FatFs module is similer to MS-DOS. However does not have a concept of current directory, all objects on the drive are specified in full path from the roor directory.</p>
|
|
<pre>
|
|
|
|
"<em>Drive#</em>:<em>directory</em>/<em>file</em>"
|
|
|
|
"file1.txt" a file on drive 0
|
|
"/file1.txt" (same as above)
|
|
"dir1/dir2/file1.txt" a file on drive 0
|
|
"2:dir3/file2.txt" a file on drive 2
|
|
"2:/dir5" a directory on drive 2
|
|
"" the root directory on drive 0
|
|
"/" (same as above)
|
|
"2:" the root directory on drive 2
|
|
|
|
</pre>
|
|
<p>The FatFs module supports only 8.3 format file name and long file name is currentry not supported. For directory separator, a '/' is used, not a '\'.</p>
|
|
<p>The FatFs module has work areas that called file system object for each logical drive. The logical drive number is specified in a numeral with a colon. When drive number is omitted, it means the default drive (0). The logical drive is bound to the physical drive that has same drive number.</p>
|
|
<p>As for the Tiny-FatFs, it has only one logical drive and always works as drive 0. Any drive number cannot be contained in the path name.</p>
