File Formats: Interchange File Format (IFF) (original) (raw)

IFF (Amiga Interchange) is a general-purpose data storage format (raster), developed by Electronic Arts, Inc. and Commodore-Amiga, Inc. that can associate and store multiple types of data. It is used by the ACD FotoCanvas Lite 2.0 and XnView applications.

IFF reads and writes RLE and non-compressed images. IFF CAT supports multipage files.

The default extension for this format is: IFF.
