Completely Delete Application

When you're all done with an application and don't want it on your computer anymore (maybe you're trying to save space or get rid of trial versions of software) you can drag the file in your Apps folder to the trash. But there are other files associated with the app that still linger on your computer, like support files and preferences.

To make sure you get rid of all of the files you can buy a program like App Zapper for $12.95 or you can get one for free. The one I use is AppCleaner. Download it into your Applications file and when you want to delete an app just drop that apps icon onto the icon for AppCleaner and it will do the rest. Nice and neat!
