Is it possible to sort or filter the file window on the total number of keywords associated with a file?
There is no such sort criteria. Only what you can find in Sort Profiles (https://www.photools.com/help/imatch/rmh_config_sortpresets.htm)
Maybe, as an alternative:
Create a data-driven category based on this variable: {File.MD.XMP::Lightroom\hierarchicalSubject\HierarchicalSubject|count:true}
This groups your files by the number of keywords they contain.
You can then use these categories to filter folders or whatever the purpose is.
Thanks, Mario.
I'd already created the data-driven category. I was just wondering if there was any other way of getting the sort I want.
I can work with that!
