I'm a bit reluctant here since 24 Bits of information is pretty small and might lead to false detections. Assuming you have a bigger collection of these files at hand: Can you confirm the version numer (byte at offset 3) is always 0x01? Also it seems the 32bit little-endian value at offset 4 has a very limited set of legal values, too ("multiple of two"); which values are around in the wild? Christoph
