Thank you boroda74, I tried a small sample and that appears to work fine.
By the way the last preset adding the zero's took about 1 hour, during which music bee appears not to respond, but when the hard drive stopped flashing I figured it was done and closed the program from task manager. Iwas processing 210GB of files so probably why.
I am unsure what the buttons, submit, download new, dowload all are supposed to do? also unsure how "Tick presets which should be automatically applied if tags have changed?
Thank you once agin for your fine preset and patient help.
