I admit, regex's give me a headache even though I try now and then. Anyway, I read through most of the posts and can't really find any analog to what I want to do. Basically, I want to reformat the filename of a song from Tags as follows:
%artist% - %title% - %disknumber%
BUT, I only want the "- %disknumber%" to appear if %disknumber% is not empty. If %disknumber% is empty the filename should display as:
My Artist - Song Title
with no trailing " - "
But if disknumber contains something like SC001 then it should appear as:
My Artist - Song Title - MyDiskNumber
Hope that's clear. Thanks for the help!
