-The purpose of File Format Identification is to determine the file format of a digital object.
+See [[Identifying Files]], [[Identifying Physical Media]].
-Basically, there are 3 ways to identify a digital object.
-==Extension==
-The file extension is used, e.g. ".doc" if the file is named "example.doc". This tells us the file ''might'' be a Word document.
-==Content Header==
-The content header is used to determine the file type based on the [[mime-type]]. As an example, your browser identified this webpage to be a "text/html" file.
-==Signature==
-The file is scanned for certain bytes, just as one would scan text looking for a keyword. Academic and forensic file format identification software make use of [[signatures]], also known as [[magic bytes]]. Each signature is assigned a unique identifier, such as a [[PUID]].
-Furthermore, all anti-virus software use signatures to detect viruses, next to using [[semantics]].
