	One of the most well-known uses of FourCCs is to identify the [[wikipedia:video codec\|video codec]] or [[wikipedia:video coding format\|video coding format]] in AVI files. Common identifiers include [[wikipedia:DivX\|DIVX]], [[wikipedia:Xvid\|XVID]], and [[wikipedia:H.264/MPEG-4 AVC\|H264]]. For [[wikipedia:audio coding format\|audio coding formats]], AVI and WAV files use a two-byte identifier, usually written in [[wikipedia:hexadecimal\|hexadecimal]] (such as 0055 for [[wikipedia:MP3\|MP3]]). In QuickTime files, these two-byte identifiers are prefixed with the letters "ms" to form a four-character code. [[wikipedia:RealMedia\|RealMedia]] files also use four-character codes, however, the actual codes used differ from those found in AVI or QuickTime files.

	Other file formats that make important use of the four-byte ID concept are the Standard [[wikipedia:MIDI File\|MIDI File]] Format, the [[wikipedia:Portable Network Graphics\|PNG]] image file format, the [[wikipedia:.3ds\|3DS]] (3D Studio Max) mesh file format and the [[wikipedia:International Color Consortium\|ICC]] profile format.
