So what did you make with the answers to your topics, you didn't even reply.  
Don't just ask the same question again in a new thread.

Also try to be as clear as possible with your requests, just "Trim filename" is not enough.  
But now you've supplied a screenshot. Looking at it, it seems you want to remove a certain amount of characters from the right side of the filename.

**In Mp3tag there are often many ways to solve a problem.**

Minna Minni (Instrumental) - We are The 1.mp3  
So you want to remove the " - We are The 1" part from it.

Your approach: Remove the last 15 characters.  
Solution for Mp3tag:  
$left(%\_filename%,$sub($len(%\_filename%), **15** ))

Maybe looks complicated, but once you have it, all you need to do is change the number to your needs.

Another approach: Just replace " - We are The 1"  
Format string:  
$replace(%\_filename%, - We are The 1, )

Now that's easy.

Even this approach from your old topics works:

(it's just a different pattern)
