.. but suddenly flashed and just moved it over in a second. Maybe this will shed some light. I'm extremely confused and worried.
I would be too. Sorry I can t offer any advice that will help.
BTW - did you move or did you copy the files. Move would worry me.
FWIW - I keep a back up of all my source files from the day they are shot ..for ever.
Important (large) projects I dedicate camera cards to the source files and keep those archived as well.
