thanks for that hint. I didn't know that.

I don't think that it works as expected or at least not as I expect
it. Or I simply don't get it right.
a) If I set a folder (=album) *and* a tag then the maintenance tool
uses every file it finds in that album. I expected that only files
tagged with the given tag are processed.
b) If I set "any albums" and a single tag I expect that all files that
are tagged with that tag are processed. But they aren't.
Also tried using DK4.0.

>>> 2) Video metadata was not refreshed if the files had an XMP sidecar.

Any ideas what's wrong here?

Best regards,
Andreas
