I just got back into Garrysmod and have downloaded some addons. I downloaded the WireSVN and I know it comes with ADVDup. On garrysmod.org some of the ADVDup files say to extract to garrysmod\data\Adv_dup or something and some say to extract to garrysmod\addons\Adv_dup. So I am wondering should it be in data or addons folder?
You want to place it into “garrysmod/garrysmod/data/Adv_dup”.
So do I move the adv dup file from addons to data?
