This tool, coupled with a keyboard, will allow you to treat your iPad as a laptop (with some limitations - iPad, not the app).
Views most files in a read only view. Quickly allows moving files from one cloud drive to another (iCloud to Ondrive to Google drive to Dropbox, etc..). Kudos to the designer. I find more functionality everyday.
