I know it is possible to run a game from the hard drive without having the cd in the drive. What I don't know is how do I do this without the file being 800 mgs? What are the files do I need to keep? What files can I ignore? Please don't think this is for piracy reasons. I am obligated to censure piracy. I ask because I gave my old PC to my son (who is 4) and believe it would be easier for him to click the icon on the desktop and deny him access to the actual CD. Your help is greatly appreciated.
