title: how to search the files inside the folders on Google Drive using Python
body: <p>I want to search the files inside the folder i.e. file from below path:
  test-download/abc/test.txt.
  But when tried the Google APIs It's giving me the separate files and folder name but How I come to know that the 'test.txt' is from 'test-download/abc'.
  Tried below code:</p>
  
  <pre><code>service = discovery.build('drive', 'v3', http=creds.authorize(Http()))
      page_token = None
      while True:
          response = service.files().list(q="mimeType='application/vnd.google-apps.folder' or mimeType='text/plain'",
                                                spaces='drive',
                                                fields='nextPageToken, files(id, name)',
                                                pageToken=page_token).execute()
          print(response)                                              
          for file in response.get('files', []):
              # Process change
              print('Found file: %s (%s)' % (file.get('name'), file.get('id')))
  
          page_token = response.get('nextPageToken', None)
          if page_token is None:
              break        
  </code></pre>
