I have two libraries. I'd like to copy files unique to the second library into the first library. The solution I've seen is to add the books from the second library to the first, setting up rules to control the adding process and then using a plug-in to find duplicates. My question is whether a plug-in exists to do something like the inverse: find unique files in the second library, which I can then look over, since errors will be inevitable, and import after that.

Thank you, and apologies if this question has been answered elsewhere.
