I'd like to free up some storage space and delete attachments from most/all the messages in my Gmail. I've long since downloaded and used any attachments I need or care to keep. How can I delete attachments from Gmail, but keep the messages?
I've read this and this, but the first is a little old, and the second is too manual. (I have thousands of messages archived. Forwarding each one to myself would take forever.) I'm looking for a less manual/tedious solution.
How can I purge old attachments that do nothing now but take up space, and still keep the original, valuable messages?
