Bonus tip: remove write protection via Command Prompt

Most SD cards have a small lock switch on the side. If the switch is in the locked position, the card becomes read-only, preventing file deletion. Slide the switch to the unlocked position and try again. If the SD card is still write-protected, use the diskpart utility to remove restrictions:

  1. Open Command Prompt as an administrator (Win + R, type cmd, press Enter).
  2. Type the following commands, pressing Enter after each one:diskpartlist diskselect disk X (replace X with your SD card number)attributes disk clear readonly

Then close the Command Prompt and check if file deletion works in iBoysoft DiskGeeker again.

Use Windows File Explorer to delete files from SD cards

If you want to use the pristine way to do the deletion, this one works even though we cannot assure you that it is fully deleted. The steps are opening File Explorer (Win + E) first, then locate your SD card under “This PC.” Try deleting files by selecting them and pressing Delete or Shift + Delete for permanent removal.

Format the SD card (last resort)

If you still can't delete files, formatting the SD card will erase everything and remove any corruption:

  1. Right-click the SD card in File Explorer.
  2. Select Format.
  3. Choose FAT32 or exFAT as the file system.
  4. Click Start to format the card.
