<h4>Description</h4>
<p>The <tt>f_chdir</tt> function changes the current directory of the logical drive. The current directory of a drive is set to the root directory when the drive is mounted. Note that the current directory is retained in the each file system object, so that it also affects other tasks that use the volume.</p>
