The files I used last night were test files with very short names (01.mp3, 02.mp3, 06.mp3),
but it's possible that I used relative pathnames for some of them (01.mp3, ../06.mp3) and
absolute pathnames for others (/home/robin/ftp/empeg/empeg-car/test/02.mp3).
I can't remember which did what now, but I have a record of it all in a scroll-buffer.
I'll check.
