Hi guys .Ive downloaded an A.I.O with 9 versions of an operating system on it.Its an iso that i had to burn to dvd because it was 850 mb.I want to burn one of the versions to cd but i'm not to sure how to do this.The 9 versions are in folders on the dvd if i drag one of the folders the into nero its only 6mb.That can't be right can it ?
