MDCD
From Just Solve the File Format Problem
MDCD is a compressed archiving utility, and its associated native file format. It was developed by Mike Davenport.
It was apparently used in some capacity by the Links 386 Pro video game.

Format details
The compression scheme is LZW with an 8K table, possibly identical to that used by Zoo. The CRC algorithm is CRC-16/XMODEM.
Identifiers
The default filename extension is .md, though some of the example commands inexplicably use .cd instead.
Identification
Files begin with the ASCII signature "MDmd".
