Q4b) And what are these "image files" you speak of?
A4b) Image files are pretty much self-explanatory. They are files made by using Alcohol 120%, Nero (yes it is possible), Clone CD, WinISO, and other various image-making programs in which the CD is directly copied from the disc and placed neatly onto your little hard drive. Ever since the dawn of legal protection in which CDs came equipped with, computer geeks all over the world retalliated! They gasped in horror and thus have worked pain-stakingly hard under excrutiating conditions to find a way around this so called "CD copyright protection" which disables the direct-copying of that commercial CD onto your blank CD. And their answer? Image files. Yep, an image file is like a xerox copy of your CD in which it is stored onto your computer. It defies the copyright protection because you just packed all of that right into that image file. Therefore now you can burn it onto a CD without the copyright protection crashing your burner. =) So.. what formats do these image files come in? Well, they come in a variety of formats. Just look for the extensions: .iso, .img, .bin & .cue, .mdf & .mds, .ccd, .cdi, etc. There are definitely a lot more, but these are the common ones. ^_^
