Hi, I have read in full the [regular expression FAQ thread](http://tions,%20Replacing,%20Case%20conversion,%20Regular%20Expressions) but did not find one, and I must say my capacity to try write mine is limited...! I hoçpe the experts in this forum could give me a hand.
By mistake I have used before the tag to tag conversion to include in my titles:
%albumartist% - %album% - %track% - %title%
I now would like to revert to the former titles I had (that were good in some cases, a bit messy in others, but never mind).
So I basically need to create an action to replace:
**(anything any length with spaces) - (anything any length with spaces) - (0 to 99 digit but also sometimes 1/12 or alike) - TITLE**
with ideally
**TITLE**
or alternatively
**(0 to 99 digit but also sometimes 1/12 or alike) - TITLE**
that is less clean but could be acceptable
I guess it can be done based on **finding the third' - ' and then deleting anything before?**
But how do you do that?
Thanks a lot for insights
Agnes

You can create an acti9on of the type "Replace with regular expression for title tha throws everything away except the stuff after the last -:
Search string:
.\* - (.\*)
Replace string
$1
Due to the non-greedyness the regular expression starts at the end.
