An ISO file (or ISO image) is an archive that contains an exact digital copy of the data from an optical disc such as a CD, DVD, or Blu-ray. ISO images are popular for backing up discs, distributing large software packages, and preserving bootable media. They store everything in a single file while keeping the structure and functionality intact.
In older Windows versions like XP and Vista, you needed third-party software to mount an ISO as a virtual drive. That changed starting with Windows 7, when Microsoft added built-in ISO mounting support. This feature continues in Windows 8/8.1, 10, and 11, allowing you to mount ISO images to a virtual CD/DVD drive instantly—no extra tools needed.
Still, if you want extra flexibility or prefer a lightweight dedicated tool, try WinCDEmu. It works on Windows 11, supports multiple image formats (ISO, CUE, BIN, and more), and has an incredibly small footprint of about 1.50MB.
