The MDX file format (Media Data eXtended) is a disc image file format similar to MDS/MDF images. It supports all of MDS/MDF format features except that all data is in one monolithic file only.

MDX file contains metadata of original media - specifically the main physical parameters of disc, such as layer breaks, sessions, tracks and other. It could be described as being an archive file containing all data from a CD/DVD. It also supports data compression. MDX file includes the magic number "MEDIA DESCRIPTOR" at the beginning of the file.

The MDX file format is supported by DAEMON Tools and Astroburn.
