What is an ISO?
An “ISO” is simply an image file. It contains all the information that is on a CD, and stores it in 1 file. Using CDR burning software we are capable of creating and writing a CD image. Not all CDR burning programs use the same format for ISOs though. Different burning programs may create different types of CD images. A few examples are:
Easy CD Creator - will create either .iso or .cif files for the CD image.
CloneCD - will create .img, .sub and .CCD files for the CD image. CloneCD versions 3 and up can also produce .cue files.
CDR Win - will create .bin and .cue files for the CD image.
Nero Burning Rom - will create a .nrg file for the CD image.
There are many other programs that can be used to create and manipulate an ISO. These programs include Winiso, Winimage, and ISO Buster. These programs are great for creating custom ISOs, extracting ISOs and testing them as well as finding out other useful information about the ISO.
Easy CD Creator is only capable of burning images created by itself or images with the .iso extension.
CloneCD can only burn images created by itself.
CDRWin can burn any images created by itself and all .cue & .bin files and it is capable of burning a .img file made from CloneCD , but if it a copy protected CDRom image the CD may not burn correctly!
Nero Burning Rom will burn all its own images and is capable of burning images with .iso extension as well as .bin & .cue.
**This is just a quick overview and is certainly not a complete list of burning or imaging programs and their functions. I wrote this a quick guide for the newbie that should help in getting started with the concepts of what is an ISO. I will have a more detailed version of this guide including more programs and their functions when I am finished writing my website! Hope this helps someone! Any suggestions or feedback welcome. -SPINESHANK-
