Action > Case Conversion (Normal) does a good job with filenaming.
when case converted in for eg. this file name 01 - aRtisT - tiTle.mp3 it will result in this 01 - Artist - Title.mp3
Is it possible to let the already capital words remain their case, and just upper case the first letter of word if they are not?
like 01 - aRtisT - tiTle.mp3 may become 01 - ARtisT - TiTle.mp3
Kind regards,
