Thank you.
I'll try other methods, as I have 16,032 epub files. See my conundrum?
And with Doublekiller AND AllDupe, sometimes it will find similarly named items. At least it did at first, like that 'Hush, Hush' example I've mentioned, it would have found that right quick. But for some odd reason, that only worked with .pdf and I don't like Adobe.
