Disk image files recreate physical disks digitally.

Disc images are digital copies of physical disks, stored on a hard drive. They come in a variety of formats, with the more common including ISO, DMG, and VCD files. Some programs create these image files as backups, to recreate a physical disc later, but virtual disk drives can mount a drive image on a system and use it as if it were a physical copy. Disk Utility, included with Mac OS X, can mount disk images. Windows users can download Daemon-Tools or Virtual CloneDrive to access these features.

Disk Utility

Open Disk Utility on your OS X system by opening the Applications folder and selecting "Utilities," then "Disk Utility." You can also run Disk Utility directly from the OS X installation disc.

Click the "File" menu and choose "Open Disk Image."

Locate the image file on your hard drive and double click it to mount the image. The image appears on your desktop along with any other connected media.


Download the installation files from the Daemon-Tools website. The free version, Daemon-Tools Lite, includes disk mounting features, and costs nothing for noncommercial use. Open the downloaded files to install the program.

Open Daemon-Tools Lite and right click on its icon in the taskbar.

In the "Virtual Devices" drop-down menu, highlight a drive and select "Mount Image." Select an image file on your hard drive and click "Open" to mount it to the virtual device.

Virtual CloneDrive

Download the Virtual CloneDrive install file from the SlySoft website. CloneDrive is freeware, costing nothing to download and use. Open the file to install CloneDrive on your system.

Open Virtual CloneDrive from the Programs list and right-click on its taskbar icon.

Highlight the virtual drive and click "Mount" from the drop-down menu.

Navigate to a stored image file on your hard drive and select it. Click "Open" to mount the image.
