Can you download file titles and locations to a spreadsheet? At least that would let me filter/sort and then go back and find the ones I want to delete. So is there a simple Dropbox search function for duplicates, or do I have to download some kind of app that will do the job. If I search specifically by name it shows me all of the versions and then I can delete the ones that are in the 'wrong' place, but I don't have the time or inclination (despite my love of procrastination by rearranging files) to search 1000 titles.

So there could be anywhere from 1-4 version of a book floating around. (No, I don't use the dreaded Kindle thanks.) So I may download it in a 'holiday reading' folder, then I may also download in the 'Publishers folder' and at some point I may have reviewed it and moved it to the 'author' folder and then maybe I have forgotten that I downloaded it in the 'lost interest in this' folder. This is not really a space issue, I have lots, but I have nearly 1000 ebooks that I sometimes file in multiple places.
