I have 300 filenames with the following 4 starting characters 0103-bobby\_womack-lookin\_for\_a\_love.flac first two is discnumber last two is tracknumber I can use tag/tag to do this,as we're lucky, we know each disc is 15 songs and there're 20 discs in total Easy fix, done in a second. But I don't like song 03/15 from disc 01/20 I want 3/15 from 1/20 (no leading zero's) How do you do that? ---
