This is a good example for the situation, where someone does not really need to learn the regular expression language, but instead use a simple action.

_Actiontype 7:_ **Import tag fields (guess values)**  
_Source format:_ **%TITLE%**  
_Guessing pattern:_ **%TITLE%.%DUMMY%**  
From:  
Gospel&spiritual 1 - Track 03.[128kb 44khz 2'34]  
To:  
Gospel&spiritual 1 - Track 03
