Many people may be unfamiliar with ISO image files and have met a lot of questions upon ISO image file using, mounting, creating and backup. In this guidance, you will learn some detailed information and practical solutions about Blu-ray ISO image file. This article is also applicable to DVD/CD ISO image files.


What is Blu-ray ISO Image File

An ISO image file, also called a disc image, is a complete copy of an optical disc, including CD, DVD and Blu-ray. ISO image files usually have a file extension of .iso.

ISO image files could be used in a variety of ways. Since ISO file is a backup of a disc, it could act as what the original disc could do when you lose or damage the original disc. You can also “mount” the ISO, which makes it accessible as if it were a physical disc, so that you could install software from ISO image file with the absence of physical disc drive. The ISO file can also be “burned” back onto another CD, DVD or Blu-ray disc, creating a copy of the original disc.

The most common way to get an ISO file is to download it from a website. However, you could create ISO image files by yourself with original CD/DVD/Blu-ray disc.
