I wonder if it was when I was experimenting with the Wifi signal. But I was still only shooting one image at a time so it shouldn’t have arrived out of order.
I may have also sent the file to trash and the sync program copied it back. I was playing with that last night too but I’m pretty sure it was after I sent the log. The Flashair Sync program is not deleting the files on the card as it is supposed to but that’s a different issue I won’t waste your time on.
Do you need to base it on time? I’m thinking generally sorting by file name should work; or at least with any camera I have used the names are sequential.
