I dug up an old copy of my Quake, but it wasnt the retail disk, was a copy that I must haved backed up some time ago. There are only two files on it. WINQUAKE.MDF and WINQUAKE.MDS. What the hell do I do with these? I know it may not run on XP but thats for me to worry about, the MDF file is 730MB so that must contain the game.
