Resource Interchange File Format (RIFF) is a generic file container format for storing data in tagged chunks.[2] It is primarily used for audio and video, though it can be used for arbitrary data.[3]

The Microsoft implementation is mostly known through container formats like AVI, ANI and WAV, which use RIFF as their basis.[4]
