Gmail 99% full

Obviously I use Gmail heavily - I'll occasionally send work files to home and vice versa, but I'm not using this account for file storage, proper. I don't want to delete shit - and I shouldn't have to either, right?

"Over 2861.671390 megabytes (and counting) of free storage so you'll never need to delete another message."

So, what now, Google? Serious. Serious.
