How to Mount an ISO Image using Daemon Tools
ISO images are files that represent a complete disc image, including all of its individual files, in a single file. Many disc-burning applications are capable of burning ISO images to a disc. However, there may be times when you wish to use a disc image as if it were an actual burned disc. This is useful when you want to try out a disc before actually burning it or if you prefer to keep several ISO images located on your computer's hard drive instead of swapping CDs. Daemon Tools is a free program that lets you mount ISO images as if they were actual burned discs.
Right-click the Daemon Tools icon in the system tray in the lower-right corner by the clock.
Move the mouse cursor over "Virtual Devices," then "Device," and then click "Mount Image."
Double-click the desired ISO image. The ISO image is mounted as a virtual drive and appears to Windows Explorer as if an actual disc was in a disc drive.
