I can't find sort of scripting function to search the position of the n-th occurence of character x in string y Maybe as hidden function ? I don't want to go into the user-defined meta-tag direction as temporary workfields, as this implies changing the mp3-files I would also be interested to know if there is a way to write own functions (or actions) useable from within scripting, this to be able to shorten tag-filename strings which are so long they aren't maintainable anymore.
