I am trying to rename my files for an audiobook series so in the car they are in order.
So the current title is just
Character1 I.mp3
Character2 I.mp3
Character1 II.mp3
Character3 I.mp3
etcetc
I want to add
001
002 etc
To the front of the file names but not sure how to automate that process.
Thanks
Tom

Hi Tom,
you can use the converter "Tag - Filename" with a formatstring like
```
$num(%_counter%,3) %_filename%
```
Kind regards
