What Is an ISO File?

An ISO file or ISO image is a single file that contains an identical copy of data saved on an optical disk, like CD, or DVD. This file is a sector-by-sector copy of the disc without compression. In other words, the entire contents of a disc can be precisely duplicated in a single ISO file.

The ISO file enables you to achieve an exact digital copy of a disc, and then use the file to burn a new disc that is in turn an exact copy of the original.

However, many people use the ISO image for making backup for their optical disc, or distributing large programs and operating systems. The reason is that the ISO file allows all the files to be contained in one easily downloadable file.
