Hi. Im new here! 🙂

I am currently trying to tag my audiobooks.

I want to have the filename like this: Author - Album 01.

Same title on them all, only with a number after the album.

For example: J. K. Rowling - Harry Potter 1 - Part 01

Or like this: Stephen King - Liseys Story 01

How can I do this as easy as possible?

Have tried to auto numbering the track number, and it worked a couple of times, but now its suddenly impossible to get a 0 first on numbers from 1 - 9. If I write 01 in the track colum, it wount save, and it's back on 1.

What am I doing wrong?

[×] Leading zeros for tracknumbers (01, 02, ...)

Ensure you have that option checked in the autonumbering wizard?

Use CTRL-S to save the changes. Do not accidentally apply tag or track before saving?

Yes, that option is checked, but it still sometimes end up as 1, not 01.

I think this happens if there are only maximum 9 tracks in a folder or the sorting makes MP3tag not see all tracks at a time in a folder.

As an alternative you may apply an action of the type  
Format value for TRACK  
Format string: $num(%track%,2)

This creates leading zeros were possible.

Please tell us on which filetype does this happen?

For MP4 it is so, ...  
because the track tag-field can hold an integer number (e. g. 1) ...  
but not a numerical text string (e. g. 01).
