So you have an ISO image, now what? You want to see what is in it before burning to a CD or DVD. May be you don’t want to waste time and energy burning the file to a disc; you just want to explore or use the content of that disk image. Is there a way to open an ISO image file without burning to a disc? Absolutely YES!
You can explore your ISO files using a disk image emulator. It’s a tool that allows you to mount ISO files. The software basically creates a virtual drive that looks like a physical CD or DVD drive on your pc. When you mount an image you will be able to explore the file as if you put in a physical disc in one of your physical drives.
There are quite a few tools or emulators available out there. One of my favorites is a tool called “Daemon Tools”. You can download it from http://www.daemon-tools.cc/home
Once installed, Just click on the program shortcut and it will start running in your system tray. You should also be able to see a new virtual drive under MY COMPUTER. If you want to open any ISO image just right click on Daemon tool icon on system tray and then highlight Device and click Mount image. At that point you just select your image just like you would open any file for any purpose. Once you have mounted the image then go check your virtual drive and you should be able to see your ISO image content as if you put in a CD/DVD in one of your physical drives. It opens image files lot faster than opening a CD/DVD from an actual drive.
I will try to give you a step by step instruction on how to download, install and use it to open a ISO file. For demo purpose, I will try to open an ISO image of my Microsoft Exchange Server CD with Daemon Tools.
Once you are on daemon tools website, look for the free downloads section at the bottom of the page.
