To access data available only as an ‘ISO disc image’ without burning you need to ‘mount’ the image. This will make the image available as virtual CD/DVD drive.
‘Windows 8’ and ‘Windows 10’ support this out of the box. Just double click on the file with the ‘.iso’ extension and it will show up in the ‘Windows Explorer’ tree.
If you use ‘Windows 7’ and older you can download below free tool from Microsoft to enable the functionality on your operating system, too.
