When I delete an app (move it to Trash) do I also need to delete its related data in
According to this:
some apps keep their data in
~/Library even after it's deleted. I find it kind of annoying that the app keeps its data even after it is deleted. The only reason I can think of that usage is maybe if I reinstall the app later, I can get my old data back. But I still prefer to deleting all its related data if I delete the app.
My second question is is this the main function of other uninstaller tools?
