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,

**From: aRtisT To : ARtisT Action "Format value" ARTIST \<== $regexp(%ARTIST%,'^.','\u$0') From: tiTle To : TiTle Action "Format value" TITLE \<== $regexp(%TITLE%,'^.','\u$0')**

... or have a look to the function $caps2() ...

**\_FILENAME \<== $caps2(%\_filename%)**
