Hi there,
I just bought GTA IV and instead of downloading the 15gb, I am trying to use my friends installation files. I have moved all of the GTA files from his steamapps/common/grand theft auto iv folder.
I moved those files to my common folder but when I click install game, it begins the 15gb download? If anyone could help it would be much appreciated, I would rather not download the huge file if I don't.
