Copy photos/eliminate dups

The short answer is: not really.  If you want to give us more details about your situation, we may be able to suggest some strategies to help you solve your problem. 

Just to be clear, the Organizer can be used to copy (Import) files from an external source such as a camera phone/pad or a camera memory card, or even from an external drive to your computer's hard drives (internal or external).  But once the files are stored on your computer, the Organizer is only a database that is used to view and manage those files.  It does not create any copy of the files that exist on your permanent storage sources.  And it is not the best software for finding duplicates.  But, as I said, if we know more about what you want to do, it may be sufficient for your purposes.
