Thank you for the link above.
I thought Lightroom might run more efficiently for me if my metadata changes weren't writing all the time to my sidecar files while keywording, commenting, editing and otherwise updating metadata. However more or less efficient Lightroom might run, if I don't manually highlight and ctrl-S my changes within each folder right after I make my changes, that efficiency is lost within my imperfect workflow. I realize my mistake can be chalked up to "user error", but I suspect that others forget to manually save to xmp as well.
It would be nice to go back and search for those files that need to have metadata written to the xmp files. I don't know of a way to do that and, unfortunately, the link above describes incomplete methods of identifying only the files I need. I understand that each file I'm looking for has the up or down arrow icon, but manually searching for these files is not easy to accomplish across several folders.
Does anyone know of a way to search the entire database for only the files that need metadata written to xmp files? Though I would prefer not to, it seems as though with my imperfect workflow I ought to have "Automatically write change into XMP" checked in my Catalog Settings.
