Order your Gmail Messages By Size
Have you ever gotten close to using up the entirety of that Gmail storage space–gigabytes and gigabytes of it–that you were sure you’d never overrun? Or are you already paying Google money every month for extra storage space? There’s finally a solution for you.
Lifehacker has discovered a simple trick to create a Google Docs spreadsheet that shows you your email messages and allows you to sort them by size–meaning you can hunt down all of those cat videos your brother sent you and delete them from your account (but be sure to download them to your computer first, of course.)
