title: How to build hierarchy by filenames list in delphi, virtualstringtree
body: <p>I have stuck with this problem.</p>
  
  <p>I have a list of filenames from an archive (here are files and folders). This list looks like this : </p>
  
  <pre><code>folder
  folder/index.html
  otherfolder
  </code></pre>
  
  <p>The problem is to make the hierarchy into the virtualstringtree.
  Files and folders that belongs will be the child nodes from a root folder.</p>
  
  <p>Any ideas?</p>
