Definition: RIFF

(1) (Resource Interchange File Format) A multimedia file format introduced by Microsoft and IBM in the early 1990s that is structured in "chunks." Each chunk identifies the type of data that follows, thus RIFF files can be composites of different audio and video content. Microsoft's AVI and WAV files conform to the RIFF format. See AVI and WAV.
