my gmod folder is 145gb

clear your cache and delete old addons youre no longer using/subscribed to as it slows down your game and takes up extra space

If you delete the add-ons you subscribe to, the problem will be solved.

how on earth have you managed that

145gb ??? Its not possible

the space comes from all the addons from the servers youre joining

mine is 80gb, maybe a lot of them is just a server content which loads while u joining it

This is the content of all the servers you visited. Just delete the folder and reinstall the game

Novice, just kidding, it's big but not that much

You should uninstall some addons. It worked for me!

stop playing on darkrp Smile and do not forget to clean up your cache folder.
