I have 11 GB game if i want to make DVD so how can i do it if my pc formate so i can install it agin?

just copying over the program data from your computer won't work. your computer has registry value that the game needs to run so unless you can find those specific keys in the reg and then after you format rewrite the registry for those games again then it won't ever work. you can save your saved data from that game but unless you have the original media (disks) for that game or can rewrite the registry then you won't be able to get it back. unless the installer is an .exe pack for the whole game, then you can just save that. since dvds can only hold like 4.7 gigs or something like that. you would have to get a dual layered dvd and your dvd burner would have to be able to burn dual layer dvds. otherwise look into a portable hard drive. ~Drac
