HEELP! Portal Models Location!!!

Hello! My name is Vic Please
Help MEE!
I was trying to find a bunch of .mdl models from Portal, like Door in test chamber, But I realize, that I can’t find .gcf files or any files in Portal folder, that could contain materials or models…
Is there any ways to find portal models?

Thanks a lot!
Sincerely yours, Victor!

P.S. I am an owner of Portal Steam Game

The files aren’t .gcf they’re .vpks. I own portal but I don’t have it installed right now but the way the other source games are labeled they may be under


or something like that.
