Is it possible to modify this string to make the "track list" of each album sorted by filename and without showing the filename?

It is now sorted by tracknumber if present, if not by title. Now I want it to be sorted by filename ASC but not show the filename.

%<artist>%|%album%|[[%discnumber%.]%tracknumber%. ][%track artist% - ]%title%

after some fixing i solved it pretty well..

%<artist>%|%album%|$if(%tracknumber%,%tracknumber%,$cut(%filename%,2)).[%track artist% - ]%title%

thnx to me
