getting rid of maps I didn't subscribe to.

I connected to a few dedicated servers, with in turn I downloaded some maps so I could play on the servers. I don’t play on them anymore, but now I can’t get rid of the maps!

They show up in the list of maps new I select Start New Game. I’m not subscribed to them on Steam workshop, and I can’t find them at all in the gmod folder.

Is there an addon my manage these maps? I don’t need them at all, and they are taking up all kinds of space on my HDD.

look at
common\GarrysMod\garrysmod\downloads\server

should be a bunch of files by {addonid}.gma

Most servesr use FastDL to download maps, in that case it would be in
common/GarrysMod/garrysmod/download/maps/mapname.bsp

That worked!
Thanks.
