What is an ISO file

Before we head to download an ISO file, let's figure out what is an ISO file first. ISO file, also known as ISO image, is a disk image that contains everything that would be written to an optical disc, disk sector by disc sector, including the optical disc file system.

ISO images can be created from an optical disc by disk imaging software, from a collection of files by optical disc authoring software, or from a different disk image file by means of conversion. Software distributed on bootable discs is often available for download in ISO image format. ISO image is able to be written to an optical disc such as CD, DVD, and Blu-Ray.
