How do I format an SD Card on a Windows 10 computer?

Make sure that the following files and folders, if installed on the SD card, are copied and moved to a safe location on your computer before formatting.

  • “CMC” folder
  • “chklst” file
  • “.ace” file
  • ""
  • ".chk"
  • Any image file extensions:
  • .JPEG (or .JPG) - Joint Photographic Experts Group
  • .PNG - Portable Network Graphics
  • .GIF - Graphics Interchange Format
  • .TIFF - Tagged Image File
  • .PSD - Photoshop Document
  • .PDF - Portable Document Format
  • .EPS - Encapsulated Postscript
  • .AI - Adobe Illustrator Document
  • .INDD - Adobe Indesign Document
  • .RAW - Raw Image Formats

After you have finished formatting copy and paste the previously listed files, if they were shown on the SD card before the format, back on to your card. 


The first step is to make sure that the slider lock on the side of the SD card is up toward the contact.  This will allow the SD card to be edited.  When the lock is engaged, the SD card can't be edited or formatted.

Now insert your SD card into a USB adapter or directly into the SD card slot if your computer has one.


Click on your Windows Start button.
