File Description

Common CD or DVD disc image format based on the ISO-9660 standard; contains exact duplicate of data on a disc; used for making copies of CDs and DVDs; 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 useful for duplicating or backing up CDs and DVDs because they copy every bit of data exactly from the disc; this is different than copying all files from a disc because the disc header information is lost in the process; an ISO file can be used to restore a disc exactly to the original version.

NOTE: Some ISO files can be loaded by a Sony PSP using the Fast Loader utility.
