Hello friends,
I have problem as example below:
%\_Filename%: **1. Free As A Bird.flac**
%Title%: **Wolny Jak Ptak**
Now, I would like to add %\_Filename% to the %Title% (but keep the original name of %Title%):
%Title%: **Wolny Jak Ptak (Free As A Bird)**
How do I do this?
I tried actions: Format value / Replace / Guess values
But it's not working!
Thanks in advance.

As I would recommend an action of the type "Format value" it would have been interesting to see what you have tried in that action.
I would have use the
format string: %title% (%\_filename%)
Or you could have looked at this thread from just a couple of hours ago:

> I have filenames like 'Allegro' and titles like 'Symphony No. 1'. I want add the filename to the title so that the title becomes 'Symphony No. 1, Allegro' but can't figure out how.

Thanks.
It is working!
%title% ($trim($regexp(%\_filename%,'^\d+.-?',)))
