| − | 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.
| + | [[Category:Top Level Categories]] |
| − | ==Extension==
| + | [[Category:File Formats]] |
| − | The file extension is used, e.g. ".doc" if the file is named "example.doc". This tells us thie file ''might'' be a Word document.
| + | [[Category:Information]] |
| − | ==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]].
