Hi all,

Just started using mp3 tag and just finding my way around it.

Using Convert -\> Tag - Filename, I know I can enter a format string, but when I want to use a track number (%track%), it produces a single digit track number. Is there any way to get the program to use a double digit track number, so that when I rename files, it comes out as "01", etc. rather than just "1"?

I'm sure this is something pretty basic, but I haven't been able to find it in the various fields available.

Cheers,  
Jasquith

Instead of %track% use  
$num(%track%,2)
