Overview

The Software Preservation Society (SoftPres, formerly known as CAPS, the Classical Amiga Preservation Society) have created their own (proprietary) hardware for dumping any kind of floppy disk from a standard PC floppy drive connected to the KryoFlux board. IPF (Interchangeable Preservation Format) is their (closed) binary format, which stores raw hardware flux transition timings and is thus able to contain (almost) any encoding, sector format and copy protection that can be found in the wild.

Identification

The documentation implies that IPF files start with "CAPS" 0x00 0x00 0x00 0x0c.
