What is an ISO image file?
An ISO image file is a duplicate copy of a complete CD-ROM disk saved in ISO-9660 format. ISO image files are widely used for storing CD content and quickly transferring it through the Internet. ISO is a common CD image format for DOS, Windows (Joliet ISO extension), Linux (RockRidge ISO extension), and other operating systems. Undisker can create ISO images from CDs, open ISO CD image files, and extract files directly from ISO images.
