Depends on what type of midi files you're trying to convert from and convert to.

If you have a midi file created on a Macintosh and want to import the file into a Windows pc you most likely can just append the suffix ".mid" to the end of the file name. Macs do not need to see the midi suffix but pcs do.

Here is a link to a freeware programs that converts between type "0" and type "1" midi files: Freeware Windows MIDI Type "0" & "1" Convertor
