I have two numbering related issues.
I just upgraded (2 weeks ago) from 2.16 to 2.17 and it seems that the "tag -\> filename" converter now uses the literal tracknumber, rather than a two digit number.
For example:
1 song1 artist -\> 1-song1-artist.mp3 in version 2.17, but in 2.16 it would have been 01-song1-artist.mp3 if I had 2 digit numbering turned on (with a leading 0)
This means that I have to renumber before I rename - an extra un-needed step in my opinion.
Here's number two; a feature request.
Is it possible to make the autonumbering wizard a little smarter? For example, if my numbers are single digit, my track listing looks like this
1 song1
10 song 10
11 song11
12 song12
2 song2
3 song3
etc...
As far as I know, I have to manually renumber the songs before I rename them.
Am I doing something wrong?
This matters to me because the CD-MP3 player in my truck plays in alphanumeric order, so all my tracks need a 2 digit number.
Thanks for a 99.99% wonderful program!

Tackett,
simply use the internal function _$num_ to add leding zeros when generating filenames from the tag. A valid formatstring would look like
**$num("%track%",2) - %title%**.
You can sort your files by the existing tracknumber via View, Sort by, Track and apply the Auto-numbering wizard on the sorted files.

Sorry, it was late and I don' think I was being clear.
I had just edited some tags that were tagged incorrectly when ripped. In fact, there were no tags, just a filename.
They looked like this:
1-song1-artist.mp3
10-song10-artist.mp3
11-song11-artist.mp3
...
17-song17-artist.mp3
2-song2-artist.mp3
...
9-song9-artist.mp3
I couldn't find a way to autorenumber them. If I sorted by filename, they ordered like 1,10,11,12,13...19,2,3,4...9 - so I had to insert track number tags by hand, then sort, then renumber, then add filename, then rename.
Again, I think this is a great product, and it's saved me hours and hours of retagging time. I want to make sure my first comment didn'y sound like a complaint or that I didn't like the software.
Thanks again,
Tackett

Tackett,
you can sort the files manually via drag'n'drop with the mouse by holding the [Alt]-key pressed. After that you can apply the tracknumbering wizard.

P.S.: Thanks for your nice feedback! I'm glad that you like Mp3tag 🙂

Thanks Florin.
I had tried dragging them, bu without the [alt] key.
Amazing support, by the way.
