Dedicated server won't upload files.

I have alot of addons for my server in the “C:/srcds/orangebox/garrysmod/addons” folder, but when my friends join the game they don’t download these files. When I spawn a prop that I’ve downloaded for my server they get a error icon, I also get it if I don’t have the same addon in the regular addons folder.

Am I doing it right or do I have to add some text somewhere on my server?

edit: Solved it nvm.
