Can i add a directory then bulk search and remove from tag, for example mine have artist-title (extended)(intro) i want to remove the (extended)(intro) from all mp3s?
I hope we are really talking about the tags - and not the filename.
Yes, you can replace data with an action of the type "Replace".
See e.g. the help
https://help.mp3tag.de/options_format.html#replace
or the FAQs:
