Unattach

I've been using it for years, from when it was still called slimbox. And I didn't hesitate to buy when it wasn't free anymore. I send and and recieve a lot of big attachments. I regularly free up my Gmail storage with it. And I can still find my attachments, should I need them.

Great and simple product. I have done it before using cumbersome Thunderbird extensions, but with a complex a tedious process, as it wouldn't work for more than a handful of messages at a time. This one works flawlessly.

Excellent product that lets you manage your google space more easily. Google makes it hard to find and remove large attachments without removing the emails they're in (that's on purpose--they want to sell you more disk space). Unattach lets you get around this and detach large attachments in a way that lets you store them on your local disk but still linked to your email. Highly recommended.
