You can decide which files to keep on your Mac and which to permanently remove.
An advantage is that AppDelete comes with a built-in help manual which comes in handy if you're new with this type of Mac program. The guide teaches you how to uninstall apps from your computer and provides you with info regarding AppDelete features.
Other useful features include the ability to batch remove apps from your Mac and to uninstall widgets, preferences panes, and plugins.
