Trim Mail attachments
If you’re trying to conserve disk space, and you’re a user of the built-in Mail application, you may be overlooking one source of disk space usage: attachments on e-mails youve received. By default, Mail leaves all attachments alone, even if you save them to another spot on your hard drive. Over time, you can build up quite a collection of old attachments. Deleting these assuming you’ve saved them elsewhere and no longer wish to keep them in Mail can save a fair bit of drive space. For example, on my machine, I have roughly 400MB worth of attached files, even though Ive saved all those files to other spots.
If you’re running the OS X 10.4 version of Mail, you can use a Smart Mailbox to help manage your attachments.
