Using Advanced Duplicator

Was wondering if anyone could help me understand using Advanced Duplicator. Wanting to get stuff for it, but, got no idea where to put it.

In the garrysmod folder, there’s a folder called date/advdup

drop txt files in there.

I’m honestly not finding it.

just use this : C:\Program Files\Steam\steamapps\your steam ID\garrysmod\garrysmod\data\adv_duplicator
