This table of file signatures (aka “magic numbers”) is a continuing work-in-progress. I had found little information on this in a single place, with the exception of the table in Forensic Computing: A Practitioner’s Guide by T. Sammes & B. Jenkinson (Springer, 2000); that was my inspiration to start this list in 2002. See also Wikipedia’s List of file signatures.
