If you have a gmail account (email). you also have much storage space available to you. well over two gigabytes. That space is supposed to be for email. Storing files there is awkward at best. Gamil Drive turns your Gamil box into a place to store files - your computer sees it as another hard drive.
You can use it to create folders, and drag, drop, open and close files as you normally.
