What are MDF files and how to open them

Are you having problems opening a MDF file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a MDF file?

MDF files have multiple uses, and Media Disk is one of them. Read more about the other uses further down the page.

Media Disk File

Files given the .mdf extension contain a disc image of data saved on a CD or DVD. MDF files are similar to ISO files, but they are saved in a different format. The MDF file must be saved with an associated MDS file for the DVD or CD data to be played back correctly.

The actual data on the CD/DVD is stored in the file with the .mdf extension, while the file with the .mds extension stores the disc's header and track information. These files allow you to play the media contained on a CD or DVD without having the actual disc in your computer's CD or DVD drive.
