Noob Question: Where do you put your downloads for models?

Well, I just got Gmod today, and I would like to download a model from the .org website. Its a model for a person, where do I upload it? And where do I find it in the game? I tried putting it in c:/programfiles/steam/steamapps/gmod/gmod but it didnt work. I dont know where to put it further. Please help! and tell me where to find it in the game. Thanks

First if all he’s new, Second try helping him in a normal way with proper grammer.

The way you type hurts my eyes, go back to Primary School and learn the basics of grammar please.
