.DAT (Dungeon Keeper)
From REWiki
Games
.DAT files are use in Dungeon Keeper to determine the graphics at the start of the game. When new areas are dug out or rooms are changed, the computer automatically generates different graphics for these areas, but otherwise everything is in this file.

Structure
Subtile map format (as found on the standard form page), with 2 bytes per entry. If you treat this as a signed integer, and take the absolute value (or rather, just reverse the sign - I've never seen a positive one), you get the entry number in the .clm file.
Notes
None at this time.
