If you’re having extra space on your Gmail account and you don’t have extra space on your hard disk, you can use that free Gmail space as a hard drive. Using a cool freeware program called Gdrive will create an extra drive inside My Computer, and every time you use this drive i.e. use files from it, is actually downloading and uploading to your Gmail account.
1. First download Gmail Drive
2. Extract the files from the downloaded file and click Setup.
3. After the installation go to My Computer and an extra drive called Gmail Drive will appear
4. Double click it and a window with the user name and password will appear
Enjoy your extra drive space:)
