How to Open a File With an Extension ISO

Files with the extension ISO contain a CD or DVD's data and file structure. In order to open an ISO file, you will need to download and install specialized software. There are a number of programs that can extract, manage, and alter the data contained within ISO files. Other programs allow you to burn the ISO file or disk image to a CD or DVD. Although some of these programs are commercial, there are a number of free programs that allow you to open a file with an ISO extension, including ISO Recorder and 7-Zip.
