Above 128GB it formats in ExFAT. There is no choice. The thing is, an ExFAT formatted&nbsp;card will allow larger continous video files. Would it be possible to format&nbsp;a 128GB or below card externally in ExFAT and use it in the camera? Any risk to disabling the card?</P> Fri, 16 Sep 2016 22:04:38 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Externally-format-128GB-and-below-cards-to-ExFAT/m-p/185606#M31769 jemanner 2016-09-16T22:04:38Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Externally-format-128GB-and-below-cards-to-ExFAT/m-p/185607#M31770 <P>But I bet the camera will go ahead and create the 2 GB files anyway.
