Hello all

I've only just started using MP3tag and I'm very enthusiastic.

My files are all APE (APEv2) and MP3 (ID3v2.3)

My folder structure :  
E:\Music\<artist\>\<year\> \<track\>

MP3tag recognizes all this perfectly.

Some of my filenames are in what MP3tag calls "mixed case"  
and I want to convert these to "sentence case" .

I've already done this on TITLE and it works fine  
but in FILENAME the is preceded by   
(some consisting of one - some of two digits).

How can I ask "Case conversion"  
to start the sentence at the first word following the track number ?

Best regards from Ray

Hello all

I'll answer myself.  
I did what should have been obvious  
and simply added "0123456789"  
to the box "word starting after"

- probably not the most elegant solution  
but it seems to have done the trick.

If there is a cleaner way of representing the track numbers,  
I'd still like to hear.  
Best regards from Ray

Hello RussellRay!

Welcome to Mp3tag forums in first place!

I've been analyzing your request/method of formatting the filename and i can show you a "cleaner" method to achieve the same purpose:

> [@](#):
>
> Menu -\> Convert -\> Filename - Filename:  
>   
> **Old Filename Pattern:**
> 
> - %1 %2
> 
> **New Filename Pattern:**
> - %1 $caps3(%2)

%1 - Represents the 1st item of the filename (Tracknumber)  
%2 - Represents the 2nd item of the filename (Title)  
$caps3- It is the scripting function "case conversion Sentence" (I.E.: artist - ALBUM - 01 tItle -\> Artist - album - 01 title)

Learn more about these clicking the following links:

Take care! 🙂
