PSFLIB (.psflib)
.psflib file signature | audio/x-psf
PSFLIB is a companion library format for PlayStation Sound Format audio, defined and maintained by the PSF community. It is used with emulators and audio players to supply shared game music data, enabling playback of tracks extracted from PlayStation software. The format is generally safe, though files may be bundled with untrusted content, and it remains a legacy format associated with retro game preservation.
