The problem can be simple or complex to solve depending on the following issues: - whether or not the file names are the same up to the extension (IMGP2002.jpg and IMGP2002.dng, for example, indicate a high likelihood that you have the same image in two different file representations; however, you might have 'birthday-2005.jpg' and IMGP2002.dng which are actually the same image). - whether or not you have edited and want to save a particular JPEG rendering in addition to a DNG rendering of the image at hand (you might have a JPEG rendering which is identical to what you have done to the current DNG, but then again you might have edited one or the other further). - whether the metadata is preserved in your JPEG files. I selected about 800 images drawn from several libraries that I needed to coalesce into the unique files. Try as I might, I could not think of a logical way to accommodate all three of the above issues via scripting alone. What I did was to use Lightroom's Library/Grid view and the metadata browser along with the various Pick and Quick Collection tools to winnow out the unique ones. The methodology I used was multiple passes like the following: - Select all - set the Pick flags to null - set the color labels to none - unselect all - set sort by capture time - use metadata browser to select all JPEGs - set JPEGs to red If the metadata is there in all the files, you can see which have duplicates pretty quickly. Walk through them fast and mark all the duplicates with a Pick flag or put them in the quick collection. Once you've got them in the quick collection, or with pick flags, filter the view to just those, select all. Turn off the filter (the selected ones will be highlighted), invert the selection (you've now got the uniques selected) and create a collection including all the unique ones. Now go to the Quick collection and walk through the duplicates, you should see which are JPEG and which are DNG (or whatever) pretty easily. Mark those which you want to delete from library or disk with a delete flag. When you're sure, use the filtering to get just those up, delete them, and scan through the whole set again to find any other duplications with variant names, etc. My path through this was complicated by the fact that I had not just DNG and JPEGs to sort out but other potential duplicates in TIFF and PSD format as well. It took me a day or so to get that 800 files edited down to the unique and best 460 or so, all in DNG or TIFF/PSD format with the edits I wanted.
