The never ending usefulness of the Trash folder notwithstanding, it is a good idea to empty it from time to time to make room for new accidentally deleted messages and to speed things up in general. Of course, Mail can do this on its own in a smart manner. But if you're a control freak or for the quick new start in between, a manual and still very fast way to empty the Trash folder (or, to be more precise, all the Trash folders in all accounts) exists.
To empty the Trash quickly in Mac OS X Mail:
- Press Command-K.
- Click OK if you are sure you won't lose anything essential.
