Formatting CF card for ML

[BAY6]

I am now shooting RAW on my 5D Mark III and everything I've ever learned was to always format the CF card in the camera.  Well, when shooting RAW I've been reading that to get the best performance is to format the
CF card as ExFat which can only be done on a computer, not in camera.  Is this correct?  Is this format still needed nowdays?

 

Thanks for the help.

Until a better answer comes around.  Formatting on the computer allows it to write special "boot" files that will boot from the card.  The EOScard utility will do this.

 

Formatting in the camera allows the camera to put the directories it expects exactly where it needs/expect them, like DCIM, etc.
