Ready? Empty it All!
There are plenty of ways to empty the Trash, but the most straightforward is to select the Finder and choose Finder>Empty Trash. You’ll have to verify that you want to empty the items in the Trash permanently. You can also use Shift+Command+Delete or Control+click the Trash icon. The latter doesn’t ask you to verify that you want to empty the Trash, though, so be careful.
There’s no hard and fast rule to tell you how often to empty the Trash; it all depends on how much you delete. I tend to empty the Trash about a week after deleting applications or projects, which is generally long enough to decide if I’ve made a mistake or if I deleted files I actually need. Here are some general guidelines:
· Empty the Trash at least once every two weeks.
· Don’t empty the Trash immediately after making a large deletion, such as an application, artwork, or several files. You might find you need them later.
· Empty the Trash if it gets larger than 1 GB.
· Empty the Trash before selling your computer.
· Don’t empty the Trash if you’ve deleted something and are getting error messages.
