No "Open file location" option.

I had recently downloaded gmod from steam again after uninstalling it to save space. When I redownloaded it, I started it up and everything worked fine. Until I wanted to add some things to it, the previously available “Open file location” button is not there anymore. Being pretty ticked off, I try putting the location name in the program bar and pressing enter. It says the address doesnt even exist. Though it must, if im playing the damn game. WHAT IS THIS SHIT?! Or am I just an idiot?

put it in addons? C:/Program Files/Steam/Steamapps/YourSteamName/Garrysmod/Garrysmod/addons/

That’s what im saying! I put that in and it says that location doesn’t exist.

Have you checked if the folder is there? (You could just make it)

Also, we need a working link to your steam profile.
