Please help me. I am trying to set sequential tags and file names for audio books.
Example I want the FILENAME to be
The\_Martian\_\_01.mp4, The\_Martian\_\_02.mp4, The\_Martian\_\_04.mp4, etc…
Second, I want the Title tag to be
The\_Martian\_\_01, The\_Martian\_\_02, The\_Martian\_\_03, etc…

Where does "The\_Martian" come from?
The numbers could be taken from the field TRACK (if that is filled) or created with `%_counter%`

I’m not sure what you’re asking. It’s a list of audio files. Multiple files making up 1 book.

How should MP3tag guess that the files should have "The\_Martian" as name?
Is that information somewhere in the tags? Do you want to enter it?

Yes I want to enter/type “The\_Martian\_\_” \

Select all the files that should get the new filename with the sequential number.
Try Convert\>Tag-Filename
Format string: `The_Martian__$num(%_counter%,2)`

I selected all files.
I then clicked Convert\>Tag-Filename
I entered : The\_Martian\_\_$num(%\_counter%,2)
I clicked “OK” and only the 1st file was renamed “The\_Martian\_\_00.mp4”

Are you sure that you entered `%_counter%` and not `%counter%`?
Because I get:
```auto
"C:\Users\me\Music\3 d sample4 - Kopie.m4a" ->
"C:\Users\me\Music\The_Martian_01.m4a"
"C:\Users\me\Music\3 d sample4.m4a" ->
"C:\Users\me\Music\The_Martian_02.m4a"
"C:\Users\me\Music\11 Stingray _ Stingray Start _ 001 _ String Ray_.mp3" ->
"C:\Users\me\Music\The_Martian_03.mp3"
"C:\Users\me\Music\100 2 b sample2.m4a" ->
"C:\Users\me\Music\The_Martian_04.m4a"
```

Yup I was not including the beginning “\_”. The filenames are now perfect thanks.
This string however does not work of the “Title” field. Should it be different there?
Thanks for the help

To set it for the field TITLE you may use Convert\>Tag-Tag for TITLE with the same format string.
