I am a professional media distributor and i use mp3tag which does almost all of my tasks in ease. I used the word **ALMOST ALL** because Mp3tag lacks one feature. Simple trimmer. To overcome this demerit i am forced to use professional batch filename trimmers ( i use File Renamer Turbo).
```
I know trimming feature already exists in Mp3tag, but do u ppl know how complicated its to use :frowning:
```
Even **Einstein's String Theorem** seems easer than that.
Regular Expression,Standard functions, $trim, $RegExp blah blah blah ... these equations made me mad.
Dont underestimate me, i have laready coined questions regarding this 6 times.

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)
