my gmod folder is 145gb

You need to clean your addons

please cleanout your addon folder and cache folder lol

clear the cache folder, the game shouldn't take up so much weight

addons? cache? a lot of lua files?

It's all of the addons you've downloaded when either playing on a server, or subscribing on the workshop

Wow you have a lot of addons, mine was 90 GB the most

wtf 145GB ? It is impossible

NAH NAH NAH NAH NAH M8888 U MAMA

I can't move, will I continue playing?

maybe of tmp files, mods, or so
