An easy addon/model pack uninstaller request

Hear me out here. I need to reinstall Gmod, but it’s been months since I played it and I forgot where I got everything and where everything goes in my Gmod folders.
I want something that will say “Hey. This model pack/addon has these files and are in these folders.”. It will do just that, and give me an option to delete or leave it alone, and show me where I downloaded it for easy access.

There’s quite alot of downloads that don’t go in the addons folder (maps especially). If you don’t know what the source is to these files/folders, you’ll never fully remove all traces of the download.
But if you had something like this, it’ll be easy. Think of it working just like Driver Cleaner Pro, except for Gmod.
