Where do I put downloaded files for a skin?

I downloaded a file from the .org place for garrysmod, but where do I put the file in steam folder. I put it in the gmod/gmod place, but I dont know where to find it.

If it’s in an addon form (the folder has an addoninfo.txt in it), stick it in steamapps/username/garrysmod/garrysmod/addons or whatever your filepath is.

If you’re Using gmod 9, i dont know, but if ur using Garry’s Mod, its located in

C://Program Files>Steam>steamapps>USERNAME>GarrysMod>AddoNs

Inside the Folder that you’ve downloaded, if theres info.txt place the folder in the directory above, if not just extract it to garrysmod folder
