Hi. Does anyone know of a way that I can get songs to be renamed, starting with the cut number of each, _but_ with a leading "0" just for those cuts with one digit? So, for example, a cut that started with "1 - " would be changed to "01 - ", _but_ cuts with two digits would remain unchanged (e.g., "12 - " would not be changed.

Thoughts/advice much appreciated!

Thanks,

DB

I assume you have the tagfield TRACK filled properly?  
Then rebuild the filename with the converter Tag-\>Filename to your wishes and use `$num(%track%,2)`.

Thank you! Frankly, I don't think I'd have figured that out on my own. VERY helpful!

Best,
