Anything I put in addons folder, doesn't work.

Ok, so a while ago i downloaded viva la sparten kick. that went in addons. doesnt work. Just downloaded a bunch of stools. they go in addons. don’t work. I downloaded stack stool, doorStool, and unbreakable and none of them are in my game! Can someone please help me?

please

Some addons might be old and outdated so that new Gmod updated have broken them. It would be better if you posted links to the files you downloaded, and posted a screenshot of your addons folder so that we can see if you’re doing something wrong.
