Quick tip… if you are using dual memory cards on the E-M1 mkII you can copy all data from one card to the other. Very hand if you need to make a backup and weren’t using dual cards.
Hit MENU button
Go to the PLAYBACK menu
Select COPY ALL
Then pick if you want card 1 to copy to card 2, or vice versa. Card 1 is the top card and card 2 is the lower one.
There you go!
