What happens when you've deleted every possible file you can part with in Gmail but you're still bumping up against the limits? The New York Times suggests a simple solution:
Rather than worry about deleting an email forever just so you can free up more space in your Gmail account, the Times' J.D. Biersdorfer suggests simply moving all your old mail into another Gmail account you create specifically for archival purposes. The idea: Once you've got all that email backed up somewhere, you can more easily delete less important email messages in your primary account without worrying that you'll lose it for good.
Their method involves using Gmail's POP access and fetching features to transfer all your email from your primary to archive accounts, but we've covered several other Gmail backup methods in the past that would also work — including automating your Gmail backups from the command line with fetchmail.

Either way, archiving before you go on an inbox purge is a smart move.
