The .MDF file extension is proprietary disk image file format used by Alcohol 120% software. Just like ISO data files, MDF files contain a precise copy a Compact disk or DVD. This file format is generally used to back up discs as well as to share the backups over peer-to-peer networks.
There are few applications that can mount/ open .MDF files with the majority of if not of all of them being only available in commercial versions although they’re also available in free trial copies.
Best Applications to Mount/ Open MDF Files
Bellow are three best known application capable of opening an .MDF file :
- IsoBuster. It could open .mdf files.It is a commercial application but, has a free trial version without any time limitations.
- Alcohol 120% can mount .mdf files in a virtual CD/DVD drive. Full-capability, free trial with time limitations is available.|
- MagicISO Magic ISO trial copy is restricted to opening 300Mb files, therefore I don’t recommend using this one.
- Daemon Tools It is a also commercial application, however the its watered down Lite edition trial version doesn’t have any feature or time limits.
I myself use IsoBuster because I find it fairly handy and will not nag you continuously to upgrade to the Pro release. It can also turn a .mdf/.mds file into the ISO format which can be practical if you intend to use the disk image with other CD/DVD programs.
How Open a .MDF Document With IsoBuster

- Download IsoBuster , follow the installation wizard to install it on your computer. When installing IsoBuster you may likely to uncheck the Include the IsoBuster toolbar option .
- Start IsoBuster , the installer generally adds a deskto QuickLaunch icon so you can easily locate when using the program
- Open the .MDF or .MDS file by clicking on File -> Open Image File. It does not really make a difference if you pick the .mdf or the .mds file in the Opendialog. IsoBuster will instantly load the appropriate disk image . Alternatively, you could open a MDF file by dragging it into the left panel of the application window (it’s the box that shows the following text “No media present” when you have just launched this program
- Extract the files : To extract a file or a folder, right-click it and go to Extract file name from the pop-up menu. You also can drag files from the IsoBuster window and drop them into any folder on your computer to copy them there.
Convert .MDF to .ISO With ISO Buster
It’s not a extensively advertised feature, yet I’ve discovered that you could actually use IsoBuster to convert .MDF/.MDS files to ISO. First of all, open the .mdf file as explained previously. Next right-click on the “CD” or “DVD” entry on the left hand navigation panel and select Extract CD/DVD Image -> RAW (*.bin, *.iso). Choose the folder where to save the converted file, make sure you save it as *.iso” file and hit Save. After a fast conversion process you are going to get an .ISO document (+ a .CUE document) that you can use with any CD/DVD burning application such as Nero.
