The File Signatures Web site searches a database based upon file extension or file signature. There is also a raw CSV file and JSON file of signatures. My software utility page contains a custom signature file based upon this list, for use with FTK, Scalpel, Simple Carver, Simple Carver Lite, and TrID. , The Programmer's File and Data Resource.File Extension Seeker: Metasearch engine for file extensions.If you want to know to what a particular file extension refers, check out some of these sites: Interpret the table as a one-way function: the magic number generally indicates the file type whereas the file type does not always have the given magic number.
