you could use an expression though to fill your keywords from the filename by using an expression in the keywords.
gappie - nice thinking, especially the edited version. Thank you!
if the files all have the same form as the ones you posted you could try to put this in keywords in the tags
That's a problem. These are files built up over 15+ years without this kind of parsing in mind. Good old Explorer Search would do the job before MC/MJ. That means there are an arbitrary number of fields, based on whatever seemed interesting in the image at the time.
My plan was to sort them by filename, select a group with the same number of keywords, then process the command for that group. Repeat for next number of keywords, and so on.
It seems like a useful feature for any semicolon-delimited field. Perhaps a syntax such as:
[Album]-[Keywords]-[Keywords+]
[Movie]-[Actors]-[Actors+] ...or...
[Album]-[Keywords]-[;Keywords]
[Movie]-[Actors]-[;Actors]
