I have a directory with multiple sub directories that have all the raw files that are catalogued in Lightroom and, here is the rub, quite a few others which are duplicates which appear to have been re-named and others which are just there. At a guess these files were created by merging or importing catalogues when I knew even less about Lightroom than I do now. The question is how can I copy out (move) the files that are not in the Lightroom catalogue so that it reduces the number of files to those active and lets me check out the files that are not catalogued?
