Are apps such as appdelete, appzapper, or appcleaner worth the money, or is it almost as easy or better to just to delete the files yourself?
I've tested all of them, and they all inevitably leave behind traces. So what I've done now is use a great Spotlight alternative called EasyFind. It finds all application related files, visible or invisible. I can't live without it. And it's free!
What traces are left behind? I did download EasyFind, and ran some searches and AppCleaner seems to do what it's supposed to.
