ISO File Format

Lists the files on a CD-ROM; based on the ISO 9660 CD-ROM file system standard

ISO files are CD/DVD disk image files based on the ISO-9660 standard format. As a disk image, ISOs contain an exact duplicate of the data stored on a disk. ISO is often used in disk backup programs as they do not lose the disk header information lost in a standard copy and paste. As such, they can be used to restore a disk’s information exactly as it had been.

ISO is used by programs like Alcohol 120%, cyberlink power DVD 10, Magic ISO, ISO Buster.
