The Short/Long naming scheme option seems reversed?
These option’s affect the way the mp3’s are displayed in the right-hand pane. If you use the short scheme in your filesystem, selecting short in the options means that it will extract the ARTIST from the directory name and show the mp3’s as ARTIST – TRACK -TITLE instead of just TRACK – TITLE. This is mostly of use when you select multiple artists/albums, because you would lose track of “which artist/which song” in the mp3 list.
