title: If I have the name of a file, how do I search a folder for a file that contains that filename?
body: <p>I have an image with the filename <code>media_httpfarm3static_mAyIi.jpg</code>.</p>
  
  <p>I would like to search the parent folder and all subfolders of that parent folder for a file that contains that name - it doesn't have to be the EXACT name, but must contain that string.</p>
  
  <p>E.g. this file should be returned: <code>11605730-media_httpfarm3static_mAyIi.jpg</code></p>
  
  <p>So this is a 2-part question:</p>
  
  <ol>
  <li>How do I achieve the above?</li>
  <li>Once I have the file, how do I return the path for that file?</li>
  </ol>
