Featured - Mount or Unmount ISO and IMG File in Windows 11

ISO images hold the information on physical media like CDs, DVDs, and Blu-ray discs in an archival file format using the file ending “.ISO”. Software makers and developers employ ISO files to deliver programs, utilities, and operating systems in this format which then can be used to create exact physical copies of those CDs, DVDs, and Blu-ray discs or to attach (mount) those as virtual discs directly to a running system

For a long time, Windows didn’t provide built-in support for ISOs. Before Windows 8, you had to utilize third-party utilities. What you should know about ISOs on Windows 11 is provided below.

The difference between ISO and IMG files

The older IMG file format was designed to allow exact backup copies of floppy disks in a single file, just as ISO does for optical discs. It works by creating a bitmap of each sector of the disk that has been written to. Since the demise of floppy disks, the IMG format has been primarily used for the creation of hard disk image files.

You may view the entire contents of an ISO image or an IMG image when you mount it on Windows 11. ISO files can be used to distribute software via bootable media images and IMG files to create exact copies of hard drives/SSDs as backups or for easy deployment of similar workstations in large organizations.

When you mount an ISO file / IMG file, your computer will handle it as if you had loaded/connected a CD, DVD, Blu-ray disc, or HDD/SSD on your system
