Disk Image File Types
Disk image files contain an exact copy of a hard disk or other type of media. They include all the files, as well as the file system information. This allows disk images to be used for duplicating disks, CDs, and DVDs. They are often used for backup purposes as well.
Common disk image file extensions include .ISO, .DMG, and .TOAST.
