MDA (Micrografx)
From Just Solve the File Format Problem
MDA is an installer-archive format used by some Micrografx products.
Identification
Files are observed to start with "MDA " (with trailing space), have "RSW!" at offset 31, and end with "NOMO".
At offset 4 is what looks to be a format version number. Known versions are (with leading space) " 1.1" and " 2.0".
Sample files
- PC Format #37 → WINDRAW/{DISK_*.MDA, INSTALL.MDA} (1.1 format)
- PC MEDIA CD 12 → ABCFLOW/{DISK_*.MDA, INSTALL.MDA} (2.0 format)
