disk images
Virtual disk copies
A disk image is an exact digital copy of a storage medium—a hard drive, CD, DVD, or floppy disk—preserved as a single file.
The image captures not just files but the complete structure: partitions, boot sectors, empty space.
Disk images allow backing up entire systems, distributing software, or mounting virtual drives: I downloaded the disk image and burned it to a DVD.
Common formats include ISO, DMG, and IMG.
