Want most every file and picture associated with your Google account? No emails.
Use Google Takeout. Check the little email notify box on the bottom left and let the takeout build. When done you can download the zip file.
You can even open docs and spreads created within Google Docs.
I am trying SpinBackUp to backup Google Drive. It is easy and works but when I download a native Google Doc, I can't view it. Spinbackup is still a good easy solution that works automatically.
