  7. Next, click on the “Format” dropdown menu.  Select “MS-DOS (FAT)” if the card is 32 GB or smaller.  If it’s a 64GB card, please select “ExFAT”.
  8. A message will appear asking, “Are you sure you want to erase the partition “[YOUR SD CARD NAME]?”  Click “Erase”. Now the computer will delete the contents of your SD card and format it.  You’re all done.
