Hi there, I can attribute the troubles you meet to the fault of Paragon NTFS for Mac. All the duplicate files occur due to Paragon's bugs and glitches provided that you mentioned that it hasn't happened to other applications. Facing this, I suggest you replace it with iBoysoft NTFS for Mac, which mounts your NTFS drive in read & write mode automatically when your drive is connected. This NTFS drive reader wins all sorts of good reviews for its excellence, you can rest assured to use it on your device.
