Sorry if I have missed it but I cannot get any of the suggestions on this forum to work with the track below.

But what I am after is 2 regex's

Firstly i have this track

**Niney The Observer - Blood And Fire [12 Version].mp3**

I would line a regex to remove the Square brackets and everything within them

and the one that just removed the brackets.

Thanks in advance for any help

**Action "Format value" ... or ... Convert "Tag-Tag" Tag-Field: \_FILENAME Formatstring: $regexp(%\_filename%,'\s\*\[.+\]$',)**

**from:  
Niney The Observer - Blood And Fire [12 Version]  
to:  
Niney The Observer - Blood And Fire**

 **Action "Format value" ... or ... Convert "Tag-Tag" Tag-Field: \_FILENAME Formatstring: $regexp(%\_filename%,'\[(.+)\]','$1') From: Niney The Observer - Blood And Fire [12 Version].mp3 To: Niney The Observer - Blood And Fire 12 Version.mp3**

To make sure to see only files having a filename with opening and closing square brackets, then for example set the Mp3tag Filter to ...  
"%\_FILENAME%" HAS "[" AND "%\_FILENAME%" HAS "]"

... or ...

To make sure to see only files having a filename with a square bracket clamp at end of the filename, then for example set the Mp3tag Filter to ...  
"$regexp(%\_filename%,'^.+?[.+?]$',)" IS ""
