Have mp3s (around 10000+ files) which have duplicates.
All the files I am talking about are in this format,
01 - Artist 1 - Title (Artist 2 Remix) (Artist 2 Remix).mp3
want duplicate texts to be removed from each mp3 file so that the final mp3 looks like this:
01 - Artist 1 - Title (Artist 2 Remix).mp3
One common condition in all the mp3 is that the DUPLICATE TEXT is always inside ( & ). I can do replace for most cases like (Original Mix) (Original Mix) \> (Original Mix) and so on...but I want to know if there exists more professional solution to remove duplicates that are within ( ).
Thanks and best regards.

**\_FILENAME \<== $regexp(%\_filename%,'^(.+)(\s\(.+\)){2}$','$1$2')**
The above regexp does not check for identical content within the round brackets.
The following regexp does respect identical content within the round brackets.
**\_FILENAME \<== $regexp(%\_filename%,'^(.+?)(\s\(.+?\))\g{-1}$','$1$2')**

Thanks 🙂
But I really dont know how to apply that regex code. Please help.
P.S. Please excuse me, I tried the FORMAT VALUE, and it worked flawlessly. Just genius.
Thanks a lot sir. 🙂
EDIT 2: One problem though.
If mp3 is in this format it dont work sir.
01 - Artist 1 - Title (Artist 2 Remix) (Feat. Artist 3) (Artist 2 Remix).mp3
Will it be possible to get this sir,
01 - Artist 1 - Title (Artist 2 Remix) (Feat. Artist 3).mp3
Means many mp3s have texts in between the two brackets such as featuring artists.

**\_FILENAME \<== $regexp(%\_filename%,'^(.+?)(\s\(.+?\))(\s\(.+?\))\g{-2}$','$1$2$3')**
Hmm, ...
why don't you create the filenames fresh from the tag fields?

it worked 😃
The problem is that the data is same in the tags or else I would have done TAGS\>FILE NAME earlier sir.
