Hi Phil, using the -n options seems not to work, perhaps I'm doing something wrong. Because I don't want to use the -n for all the commands, I append it by using "-execute" like this: ... -execute -n -XMP:DateTimeOriginal="2007-10-31T09:25:27.08+01:00" The I get error: "Invalid date or time format (should be YYYY:MM:DD HH:MM:SS[+/-HH:MM]) for XMP-exif:DateTimeOriginal Nothing to do."
