I guess you're right, Paul. I was trying to accommodate the scenario where one might have the same file or filename in more than one location, but while possible, it is not likely. If it complicates things further, then I should prevent any duplicates. But the previous code did not do that, and your latest version filters only if duplicates are selected from the same folder. How can I change it to always filter out dupes regardless of source (and retain the complete folder path in the msg box)?
