IFF file extension

Interchange File Format

The .IFF file format is a generic format created by Electronic Arts and Commodore back in 1985, but is now considered redundant.

.IFF files could contain any kind of data such as graphics, audio, text, save games etc.

The actual format itself is made up of sections called 'chunks', which are defined by four-letter IDs. The three types of chunks are:

FORM - defines the format of the file
LIST - includes the properties of the file
CAT - includes the remaining data
