I've been experimenting with a few tools to do useful things in directories full of .abc tune files: Session lister — Tune lister — Collection lister These are "works in progress" that I've included here to get ideas for making them more useful. Another experiment: The tunes here, one per file, have names derived in two or more different ways from the tune's title. This is to get ideas about what styles of file names are useful for different purposes.
