MIDI file stored in the Resource Interchange File Format (RIFF); technically, a MIDI file wrapped in an RIFF container; the format was originally introduced by Microsoft and later extended by MIDI.org; often referred to as a RIFF RMID file. Contains MIDI information, but does not contain actual audio data.
Files with the RMI extension identify a data known as Java Remote Method Invocation application programming interface. The RMI data files are used to generate Java technology-based applications and programs. The RMI files support Server, Web and Internet Java processes.
