An ISO file is a common CD or DVD disc image format based on the ISO-9660 standard. It contains an exact duplicate of data from the original disc, which includes the data saved on the disc as well as the filesystem information, such as directory structures, file attributes, and boot code. ISO files are often used for making copies of CDs and DVDs.
