+<h2>FIL</h2>
+<p>The <tt>FIL</tt> structure (file object) holds the state of an open file. It is created by <tt>f_open</tt> function and discarded by <tt>f_close</tt> function. Application program <em>must not</em> modify any member in this structure except for <tt>cltbl</tt>, or the FAT volume will be collapsed. Note that a sector buffer is defined in this structure at non-tiny configuration (<tt><a href="config.html#fs_tiny">FF_FS_TINY</a> == 0</tt>), so that the <tt>FIL</tt> structures at that configuration should not be defined as auto variable.</p>
