I plugged my SanDisk SD card into my Macbook pro. I then highlighted all pictures, control clicked and selected 'new folder with items'. However, instead of the new folder being created, instead all pictures on the SD card have disappeared (including a few I did not highlight). No folder has been created and there seems to be no sign of my images anywhere on the SD card nor the laptop.
Thanks for any help, major panic as these photos were for somebody else!
