This app is cool. The huge gmail account space is put to good use other than mail.
Check this out GMail-Drive-shell-extension
Install that and you will see a Gmail drive in you' My computer' then right click on the drive and chose 'login as' to give your gmail username and password and its done. Now your ready to use the drive like you use your other drives. Drag and drop files create folder etc. Make good use of all the gmail space.
All files are sent as emails behind the scenes so if you actively use the gmail account create a filter to directly archive those messages.
