The Microsoft blog “Building Windows 8” reported today that the company’s next operating system, Windows 8, will support natively mounting ISO and VHD files. As a bit of background, ISO files are all the folders and files included on a CD or DVD encapsulated into a single file. Similarly VHD files are all the files and folders on a hard drive encapsulated into a single file. These VHD files are used primarily by Virtual Machine and imaging backup programs. Just as the OS did not support zip files out of the box for many iterations, ISO mounting has always required third party tools like Daemon Tools and SlySoft’s Virtual Clone Drive. However, it looks like the time has finally come for Microsoft to roll ISO mounting into the operating system. Steven Sinofsky stated that managing ISO and VHD files continue to be important for businesses and power users and that “we know even more support for VHD is a big request, so stay tuned.”

Rajeev Nagar, the group program manager on the Storage and File Systems Team, detailed how the ISO and VHD mounting will work in the upcoming Windows OS. For ISO files, users need only to select the ISO and choose the mount option in the Windows Explorer ribbon interface. Windows will then create a virtual CD/DVD drive with the files contained in the ISO available. The drive will also be able to eject the ISO file from the ribbon interface with a single click.

On the VHD, or Virtual Hard Drive, front, it is only a matter of double clicking on the VHD and allowing Windows to assign a drive letter and presenting users with all the files and folders contained in the VHD file. User will be able to interact with the virtual drive just as they would with a “normal” hard drive.

One issue with the ISO and VHD support in Windows 8 is that while users will be able to mount and interact with ISO and VHD files, they will not be able to create the files from scratch. Makers of ISO burning and VHD creating utilities are likely to appreciate still being relevant. Still, its a welcome step in the right direction for power users.
