+<h4>Description</h4>
+<p>The <tt>f_chdir</tt> function changes the current directory of the logical drive. Also the current drive is changed at Unix style volume ID, <tt><a href="config.html#str_volume_id">FF_STR_VOLUME_ID</a> == 2</tt>. The current directory of each logical drive is initialized to the root directory on mount.</p>
+<p>Note that the current directory is retained in the each file system object and the current drive is retained in a static variable, so that it also affects other tasks that use the file functions.</p>
