What is an SFI file?

SFI files mostly belong to DIRAC Simulator. Audio Impulse Response Files: This is the most common use for SFI files. They use the RIFF container to store impulse data, known as Spatial Field Impulse or the Sound File Impulse Response Format. Programs like DIRAC Simulator and Sound Forge work with these files for spatial audio processing.
Scanned Image Files
Some SFI files hold scanned image data, often linked to applications such as PhotoShop.
GIS/CAD Data Files
Other files with the SFI extension come from Georgian Software Systems and are used in GIS/CAD work, supported by tools like SuperFin and systems from Novapoint.
Key Points as outlined by FilExt.com:

Verify the internal format (e.g. RIFF for audio data).

Match the file type with the appropriate software depending on its origin.

Audio versions focus on impulse response data for sound simulation.

Image or GIS/CAD versions require graphic or mapping applications.
