title: List all files in a Google Drive folder and sub folder recursively via the REST API
body: <p>Is there a way through the Google Drive API to list all the files in a specific folder and its sub folders with out traversing the folder tree and making requests for each folder?</p>
  
  <p>The <a href="https://developers.google.com/drive/api/v2/reference/files/list" rel="nofollow noreferrer">File:list</a> and <a href="https://developers.google.com/drive/api/v2/reference/children/get" rel="nofollow noreferrer">Children</a> methods of the REST API only appear to return the files of a specific folder as far as I can tell. Essentially I want the do equivalent of <code>dir /s</code> in windows.</p>
