No gamemodes folder!

I was downloading the rp gamemode and i was told to put it into the gamemodes folder. I cant find one! Where is it located? And if its not there what should i do?

…Make one.

Does that work? And if so where do i put the folder?

search for “gamemodes”…it does exist it always exist unless you delete it manualy

no, i reinstalled gmod yesterday, and there was not any gamemodes folder.
The path need to be like: steam/steamapps/<your_steam_account>/garrysmod/garrysmod/gamemodes.
