Lost my addons and garrysmod folder.

Does anyone know how to retrive your addons and garrysmod folders because i tried to download something today but i cant find addons or garrysmod folders its like it vanished into thin air i searched my hard drive completely and i didnt find them but if anyone can help it would be great because without my folders its like playing garrysmod without the mod.

PLEASE?

you can… re-download the shit and it gets fixed

how may i ask?

Or you could try an file undeleter.

so what your saying if i download any file addons and garrysmod folders will come back?

well i can download but it doesnt appear in my game

Start the game, exit it then your garrysmod folder will be created.
Then you shall have an addon folder as well.
