I regularly receive emails with very large attachments (uncompressed scans, photos, videos, etc.). Obviously, the sender could have done me a favor by compressing the files before sharing. But not everyone takes the time or even knows how to.
To save space in my inbox, I can either delete the message or if I'd like to keep it for later reference I can (with the message selected) click on "Message" in the menu bar followed by "Remove attachments".
However, what if I'd like to keep a compressed version of the files for later reference as well? Is there some way to do this?
