I installed Arma Combined Operations off the anniversary disc. Now I want a new CD key to play DayZ as that one is my brothers so I purchased Arma 2 and Arma 2 Operation Arrowhead on steam.
Can I transfer the Arma files that I already have to the Steam folder so I don't have to download it? I have limited bandwidth.
I've tried to put it in steamapps under common and in the the folders that Steam makes for it when downloading. But it doesn't work it just tries to download it.
