ISO is a sector-for-sector copy of an optical disc — Linux distributions, old software and game discs all ship as ISO files.
Typical use: Extracting an ISO to ZIP gives you the files inside without mounting or burning anything.
About the ISO format
ISO is a sector-for-sector image of an optical disc: the entire contents of a CD or DVD, byte-identical, in one file. Linux distributions are distributed as ISOs, old game discs are archived as ISOs, and virtual machines mount them as virtual drives.
You cannot simply double-click one open. The usual choices are burning it, mounting it, or — the undemanding option — extracting the files inside to a ZIP, which works everywhere and needs no drive at all.
