AppZapper

The programs you install in the Application folder generate some system files in which they sstore extra information, cache and user config.

Uninstalling a program is as easy as drag and drop the icon of the program into the recycled bin, however, those associated files remain in your computer, just occupying space. That's the reason you'll welcome AppZapper.

AppZapper is a cute application that will find all related files and will ask you to confirm the deletion of those files.

AppZapper also includes a window which will tell you the version you installed and last time they were run, so you can check if the program is important or not.
