how can i empty the gmod folder completely

like the title says I need to empty my gmod folder because its chockfull of addons that I barely use anymore

select all files then SHIFT + DELETE

like inside the second gmod folder because that sounds kinda dangerous, or in the addons folder?

If you delete the second gmod folder, it’ll redownload itself when you play it. You shouldn’t worry about it.

You can freely delete the gmod folder because it only contains the custom stuff of the user. Any files needed for the game to run are inside the gmod gcf in the steamapps folder.
