<p><strong>Description:</strong></p>
<p>The <code>drivefree</code> method can be used to detect the space available for memory storage on a device.</p>
<p><strong>Argument:</strong></p>
<ul>
<li><p><code>drivename</code>:</p>

<p>Specifies the name of a drive to be examined.</p>

</li>
</ul>
<p><strong>Return value:</strong></p>
<p>If the drive exists, this method returns an integer value indicating the available space on the specified drive, measured in bytes.</p>
<p><strong>Example code:</strong></p>
<pre class="codeblock" id="GUID-B6522445-704B-4521-9A80-DBF635EA7526">function checkDrivesInformation() {
  var space = 0;

  for (var i=0; i&lt;drives.length; i++) {
