Hi all,

My music library is tagged with COMPOSER being the full name of the composer (Ludwig van Beethoven, Carl Maria von Weber, Gustav Mahler etc). I'd like to rename this to Beethoven, Ludwig van or Weber, Carl Maria von etc.

So the last 'word' becomes the first, then a , and then the rest. Can anyhelp help me with this formula?

Much appreciated!

Ralph
