I was able to rename them manually after the sync via Tools -> Library Tools -> Rename Files From Properties.
But an option to do that automatically during the sync would be even nicer.
Also, does anybody know if it's possible to set up a rule to create directories and "group" the files by artist?
e.g. : A-E, F-M, N-T, U-Z.
My player has a limit on the number of dirs it will read, so I kinda need that capability.
