title: Granting APP authorization to Google Drive files
body: <p>I am trying to authorize files on my google drive with specific APP authorization I created. As files on my google drive can only be manipulated by its authorized app, is there any way I can convert these "None" authorized file with APP authorization? And, if yes, by which function? </p>
  
  <p>I looked all over the tutorial document but only find discussion about permission. The only method I can think about is uploading these files to google drive with upload function from my created app. But I guess there is a much smarter way. Do any one has the same experience?</p>
  
  <p>Here list my steps to create authorized file:</p>
  
  <ul>
  <li>First, I start my app from using sample code, DrEdit. <a href="https://developers.google.com/drive/examples/python" rel="nofollow">https://developers.google.com/drive/examples/python</a>; </li>
  <li>From the code, I successfully open new files and saw them listed on my google drive. </li>
  <li>From view authorized app, I can clear see these apps created from my app have their authorization signed with app ID. The other files original belong to me have these authorization signed as "None".</li>
  </ul>
