Problems with adding mods to Garrysmod 10, please help!

For some reason when i add mods into the addons folder, it doesn’t appear in the game and i dont know why. THe mods are from “garrysmod.org”, Do you just extract the m to the addons folder or is there mor estuff i need to do?

Be sure not to put the .zip in, but the folder.

I extracted them using WinRaR, and deleted the .zip file, but still no luck

Most downloads from gmod do go into the addon folder, but some things like maps go respectively into the maps folder, try posting a link so that we could see what you’re trying to add.
