What is mds file? How to open mds files?

File type specification:

Disk image (ISO) binary file type icon Disk image (ISO) binary file type

mds file icon: mds filetype icon

File extension mds is primarily associated with Alcohol 120%. An MDS file is an optional media descriptor file that can be generated when you create a disc image from a CD or DVD. The format is a binary file with the ASCII identifying characters "MEDIA DESCRIPTOR" appearing in the beginning of the file.

A typical .mds file contains metadata about the original media, specifically the position of the layer breaks or layer breach bit, a property of the copy protection feature of many DVDs. An MDS file is then used in conjunction with its related disc image (MDF) to re-create the DVD.

MDS file can be created by optical disc imaging applications. The MDS file format is mainly used by the Alcohol 120% application, but some other disk and emulation tools are using it. Its a favourite image format for backup exact copies of original game disc.

If you were interested in MDS file, you might have been also interested in MDF file format.
