File Format Identification is the process of figuring out the format of a sequence of bytes. Operating systems typically do this by file extension or by embedded MIME information. Forensic applications need to identify file types by content.
* Written in C.
* Rules in /usr/share/file/magic and compiled at runtime.
* Powers the Unix “file” command, but you can also call the library directly from a C program.

==Digital Preservation Efforts==
PRONOM is  a project of the National Archives of the United Kingdom to develop a registry of file types. A similar project was started by JSTOR and Harvard as the JSTOR/Harvard Object Validation Environment. Attempts are now underway to merge these two efforts in the Global Digital Forman Registry and the Universal Digital Format Registry.
The UK National Archives developed the Digital Record Object Identification (DROID) tool, an "automatic file format identification tool." This tool is written in Java and can be downloaded from SourgeForge.

=Data Sets=
If you are working in the field of file format identification, please consider reporting the results of your algorithm with one of these publicly available data sets:
* NPS govdocs1m - a corpus of 1 million files that can be redistributed without concern of copyright or PII. Download from http://domex.nps.edu/corp/files/govdocs1/
* The NPS Disk Corpus - a corpus of realistic disk images that contain no PII. Information is at: http://digitalcorpora.org/?s=nps
Current research papers on the file format identification problem. Most of these papers concern themselves with identifying file format of a few file sectors, rather than an entire file.  '''Please note that this bibliography is in chronological order!'''
