<p>Hi, <br>
</p>
<p>I refactored the class and add the following behaviors:</p>
<ul>
<li>insert an excludePattern to exclude directories and files.
Handy for invisible files/directories starting with a dot</li>
<li>sort the directories and files in the menu</li>
<li>refactored the code and improve understanding </li>
</ul>
