New to G-mod, SAVE file help!

Hi, I’ve played GMod for about a week or so and I understand how to place addons off into my addon folder and the whole proccess of extracting files. BUt my problem is when I view a file that says readme or something like that and it tells me to put it in the SAVE file folder I do… THen I open Gmod and click load game and theres nothing there with anything in it… Were do I find the things in my SAVE folder?
