Spawn menu issue

I installed a bunch of addons and recently had a clean install of Gmod, and wiped all my addon folder clean. How can I get rid of the folders (which only contain error symbols now) in my spawn menu? I realize this is most likely a noob question and can probably be solved by the simple click of a button.

Thanks in advance!

you go to C:\Program Files\Steam\steamapps(steamname)\garrysmod\garrysmod\settings\spawnlist and delete any txt file you want

Actually, it would be a better idea to delete ALL of them, since the ones that are still installed will replace themselves.

So if I delete all of them, the addons I currently have installed will keep stay in the spawn menu?

Thanks a bunch!
