This is all deeply confusing so I'll make no comment on Arthur's predicament, let alone John's incomprehensible, yet I assume meaningful, reply. I'll just note that when I transfer files to my computer I copy and paste to the appropriate folder, which avoids messing with Nikon's not always superb software, and leaves everything intact on the card until I decide that the operation has concluded successfully and I can go ahead and format it.

now, where's that "smug" smilie?
