L4D model pack

I found the model pack from the demo on garrysmod.org, extracted it to my addons folder, and when i browse for the models while in-game, it shows the folders with nothing inside of them. I’m new to all of this. Just got Garry’s Mod a few days ago and i’ve been playing around with it. Can anyone help me out here? I would sincerely appreciate it!

I think the L4D models are in a different format than Gmod’s. I believe the engine is different (although still Source) as well, so incompatible models should be expected.

I would consider that always but since it was hosted on the garrysmod.org site I figured it would be compatible. ( Sorry for being a Smartass ^^ )
