Media Descriptor File or MDF is a disk image file format that was designed by Alcohol Soft to burn data onto CDs and DVDs. As an optical disc authoring tool, it serves as a point of convenience for users who want practical access to certain files. Compared to ISO files, MDF is able to contain different layers of data in raw form.
When working with MDS files, it may be accompanied with a MDS file which is a file type that stores metadata. MDS stands for Media Descriptor Sidecar and this means that it is able to include indications for where data belongs in an MDF file. This includes starting and ending layers, values, locations and other relevant information. Although .MDS is helpful, an .MDF file can exist without an MDS file.
On Windows PCs, MDF files are not natively supported. Therefore, unpacking, opening, and mounting them on Windows 11 or 10 computer requires external tools and programs for easy access. We’ve included the best steps to take if you’re looking to unpack, launch, and view an MDF/MDS file content on PC.
