Addons in Windows 7

I just had my computer upgraded, and don’t completely bomb me for this, but i forgot the file path to put addons into Garry’s Mod. Can anyone tell me?

program files/steam/steamapps/username/garrysmod/garrysmod/addons

Start -> Search. “garrysmod”. Wait 10 seconds. There you go.

but do you run or save the file to download it there? sorry my old pc glitched me out of getting addons but the new ones great!
