As an example, most distributions of Linux release ISO images of the installation CDs. ISO images are mainly used as source files from which to create CDs. Image files, unlike normal files, are usually not opened rather, they are mounted.Īn ISO image (.iso) is simply a CD-ROM image saved in ISO-9660 format. This file not only contains individual data files, but it also contains track and sector information and arranges all this information in a file system, just like disk media.
