drive.file
With this scope rclone can read/view/modify only those files and folders it creates.
So if you uploaded files to drive via the web interface (or any other means) they will not be visible to rclone.
This can be useful if you are using rclone to backup data and you want to be sure confidential data on your drive is not visible to rclone.
Files created with this scope are visible in the web interface.
