Part 1. What is an ISO File?

An ISO file, often referred to as an ISO image, is a single file that perfectly represents a complete CD, DVD, or Blu-ray disc. The entire contents of a disc can be precisely duplicated in a single ISO file. It is often used for distribution of software, backup, software installation, or operating system installation.

The name "ISO" comes from the ISO 9660 file system used with CD-ROM media, but it also refers to the ISO 13346 standard which is used for DVD and Blu-ray. And to make ISO image, you need a perfect program to help you. Next, we are glad to introduce you the 4 best free ISO makers and show you how to convert DVD to ISO.

What is the Difference Between ISO and Bootable ISO?

An ISO file, or ISO image, is a type of disk image that contains an exact copy of data from a physical disc, such as a CD, DVD, or Blu-ray disc. It includes the filesystem and all files and folders on the original disc.

A bootable ISO is a specific kind of ISO image. In addition to containing an exact copy of data from a physical disc, it also has the necessary startup information for a computer to boot (start up) from this image instead of its regular operating system when it's burned onto a USB drive or CD/DVD. This feature is often used for installing new operating systems or running live versions of an OS directly from the media without installation.
