A '''FourCC''' ("four-character code") is a sequence of four [[byte]]s (typically [[ASCII]]) used to uniquely identify [[File format|data format]]s. It originated from the '''OSType''' or '''ResType''' metadata system used in [[classic Mac OS]] and was adopted for the [[Amiga]]/[[Electronic Arts]] [[Interchange File Format]] and derivatives. The idea was later reused to identify compressed data types in [[QuickTime]] and [[DirectShow]].
