How to Open an MDF With UltraISO

By Jason Artman

A computer file with the extension MDF contains a complete copy of the data on a CD-ROM or DVD-ROM disc. Using software that supports MDF files, you can burn an MDF file to a physical disc and have a copy of the disc originally used to create the file. Windows 7 has direct support for burning image files to discs, but only if those images are in the ISO format. UltraISO has the ability to burn MDF files to discs or to convert them to ISO files.

Things You'll Need

  • Blank CD/DVD

Step 1

Launch UltraISO using the desktop or Start menu shortcut.

Step 2

Click the folder button at the top of the window. Alternatively, click the "File" menu and then click open, or press "Ctrl" and "O" simultaneously.

Step 3

Double-click the MDF file that you want to open. The contents of the disc image appear in the upper-right corner of the UltraISO window.

Step 4

Insert a blank disc into your computer's optical drive, and click the "Burn CD/DVD Image" button at the top of the window to burn the image to a disc. Alternatively, click the "File" menu and then click "Save As" to save the image as an ISO or other type of image file.
