Hello all. I use Nikon NXD for editing my photos, the transfer built in with nxd has many options, one I use is to tick box for deleting files after downloading, This has worked fine with my Nikon D800e, I traded in the 800e and bought a Nikon D850 ,with the same transfer setting the files are not deleting.I know that I can delete files by other means.I was wondering why things are different with the D850. has anyone any answers. many thanks.
