What is a RIFF file?
Image saved by Corel Painter, a digital art studio used to create digital paintings; contains raster graphics split across one or more layers; allows the painted graphics to be separate from the canvas so that artists can customize the canvas later.

NOTE: RIFF files may also be opened using Corel Painter Essentials.
