.MDS and .MDF files are created using Alcohol 120% or Alcohol 52%. They are both disc image files. The .mdf file works similarly to a .bin image and the .mds works similarly to a .cue sheet track, holding extra information about a disc's structure. Disc images recreate the files, function and structure of a CD or DVD-ROM. To mount the Alcohol-created disc images, you only need the .mdf disc image. While Alcohol Soft created the format, there are multiple programs you can use to mount a .mdf disc image.
Mounting the .mdf with MagicISO
Download, install and open MagicISO (see Resources).
