Alright guys, so I'm download this game online for my computer and it has different parts to download: part1.rar, part2.rar, part3.rar, ect... so what do I do once I've downloading every file? Stitch them together to make the whole game somehow? Extract them all into one folder and use some kind of software to mend them? I'm so lost, can someone give me step by step directions on what to do? I read something about iso something or other and got lost, sorry for my pc noobiness
