<p class="Pp">The <code class="Nm">msdosfs</code> driver will permit the
    <span class="Ux">FreeBSD</span> kernel to read and write MS-DOS based file
    systems.</p>
<p class="Pp">The most common usage follows:</p>
<p class="Pp"></p>
<div class="Bd Bd-indent"><code class="Li">mount -t msdosfs /dev/ada0sN
  /mnt</code></div>
<p class="Pp">where <var class="Ar">N</var> is the partition number and
    <span class="Pa">/mnt</span> is a mount point. Some users tend to create a
    <span class="Pa">/dos</span> directory for <code class="Nm">msdosfs</code>
    mount points. This helps to keep better track of the file system, and make
    it more easily accessible.</p>
<p class="Pp">It is possible to define an entry in
    <span class="Pa">/etc/fstab</span> that looks similar to:</p>
<div class="Bd Pp Li">
<pre>/dev/ada0sN		/dos	msdosfs		rw	0	0</pre>
</div>
<p class="Pp">This will mount an MS-DOS based partition at the
    <span class="Pa">/dos</span> mount point during system boot. Using
    <span class="Pa">/mnt</span> as a permanent mount point is not advised as
    its intention has always been to be a temporary mount point for floppy and
    ZIP disks. See <a class="Xr">hier(7)</a> for more information on
    <span class="Ux">FreeBSD</span> directory layout.</p>
