title: Remove a bit of a string before a word
body: <p>I have string like this:</p>
  
  <pre><code>G:\Projects\TestApp\TestWeb\Files\Upload\file.jpg
  </code></pre>
  
  <p>How can I remove all text before "Files" (G:\Projects\TestApp\TestWeb)?
  The string before files can changed, so I can't count characters and remove them after 20 characters.</p>
  
  <p>Thanks for your help :)</p>
