There have been a lot of topics covered in this thread. Paul's original question was very broad. My first broad answer is that ABC programs tend to be shareware and cheap. My favourite for PLAYING ABC tunes, converting to Midi and giving a reasonable assessment of chordal accompaniment is ABCMUS from Henrik Norbeck.

Bruce, the advice from Alan is very sound. WinZip is very friendly for zipping complete directores of files.
