Creating an ISO Image

Ask a question
Creating an ISO image is an important step in copying data from one CD/DVD to another, or writing fresh data to one of these storage mediums. An ISO image archives data to be written to a CD/DVD, which can then be burned using disk burning software. ISO images provide an easy way to store data at an intermediate stage before the software writes the data on a disc.

This article explains what an ISO image is, how to create one, and how to burn one onto a CD-ROM or DVD-ROM. It also lists the software and the URLs that can be used for creating an ISO image. The exercise of creating an ISO file is demonstrated with screenshots to make it easier to understand.


What is an ISO image?

An International Organization for Standardization, or ISO, image is an archive file composed of the data contents of every written sector of an optical disc, including the optical disc file system. ISO image files typically have a file extension of .iso.


An ISO image is created by software and is the replica of an existing file system. This image can include the whole content of a DVD-ROM or a CD-ROM. The program that will be used to open, create, edit, and extract the DVD image file will allow you to convert the extracted contents into an ISO image that will burn the exact contents onto a DVD.

How To Create an ISO Image

To create an ISO image, you should first download the correct software to create this type of file. Some of the best, free ones include Magic ISO, ISO Recorder, and Nero Burning ROM.

How To Read an ISO Image File

You can read ISO images using a virtual disk reader, like Daemon Tools. Alternatively, you can burn a CD's image using a disk burner and a program designed to do so.

You can also open an ISO file or extract its contents using a compression/decompression software, like 7-Zip or WinRAR.
