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

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 copy process. An ISO file can be used to restore a disc exactly to the original version.

Windows 7 includes a utility called Windows Disc Image Burner that can burn ISO images to CDs and DVDs. The utility is located in the \Windows\System32\ directory and has the filename isoburn.exe.

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