The HOG format is used by Descent to store some of the game data.

File format


The file begins with the three characters "DHF", which presumably stands for Descent Hog Format.

File entry

After the signature, the file consists of one or more file entries, one after the other.

Data type Name Description
char[13] filename Null-terminated 8.3 filename (lowercase, padded with \0)
UINT32LE size Length of the data
BYTE[size] data File content, size bytes of data


  • Descent will refuse to load the HOG file if it contains more than 250 files.
  • Some websites erroneously report the signature as DHFmoon01.bbm, but moon01.bbm is actually the first entry (a LBM File) of the DESCENT.HOG.
  • HOG appears to stand for the animal, as other files in Descent are named after pigs, like *.PIG or *.HAM.


The following tools are able to work with files in this format.
