The SF2 file format, standing for SoundFont 2 Sound Bank, is a type of file used to store instrument samples and musical sound presets that can be played back using MIDI data. It's an evolution of the original SoundFont format, designed to provide a standardized way for synthesizers and software music players to access a wide variety of sounds, from instruments to sound effects.
An SFZ instrument package - a zip archive of .sfz instrument definition files and the wav samples they reference. Filestar writes this bundle when converting a SoundFont (sf2 or sfark); extract it and point an SFZ player such as Sforzando or LinuxSampler at any .sfz inside.
