The bmz file extension is associated with Demon Stalkers, an action computer game developed by Electronic Arts for MS-DOS PCs and Commodore 64 computers in 1988.
A bmz file stores various game data. It is a proprietary file belonging to the original game and is not a general-purpose interchange format. The format is now associated with this legacy release.
A bmz file is intended to be read by Demon Stalkers, rather than opened as a standalone document. Run the game in a suitable MS-DOS or Commodore 64 environment and keep the file in the location expected by the game.
There is no meaningful general-purpose conversion for a bmz file. The file contains data for Demon Stalkers, so it should normally be kept with the game and used in its original form.
