> JIF/JIFF are archaic now and replaced by the widely accepted JPEG format Too bad. IFF was a good file format that made it easy for programs to add extra data without breaking reading on other programs. AIFF, TIFF, RIFF, AVI all were based on it. I can't tell whether JIF was. [Looks like a mess of formats for JPEG](https://en.wikipedia.org/wiki/JPEG_Interchange_Format#JPEG_files) (JIF, JFIF, and EXIF, and a combo of the last two).
