I like to keep my track numbers in xx format - 01, 02, etc. When I edit the ID3 tag via Directory Opus and save it, the initial 0 is stripped from the track number, so 01 becomes 1. Is there any way DO can respect the default format?
I don't think it's configurable.
FWIW the music player I use lets me configure whether or not it adds padding when displaying the tags so it doesn't matter exactly how they're stored in the file. Maybe the tool(s) you use can be configured that way as well?
