not enough disk space?!

I cleared out my garrysmod directory completely. deleted everything except for a few select addons, but when i go to run the game (to restore some files i deleted) i get an error that says “there is not enough disk space to run this game please free up disk space and try again.” I have about 170 gb left, (sarcasm) and i dont remember gmod being that big…in fact…thats pretty big for most games…i think (sarcasm)
