When I try to delete .MOV files from my iPhone X (running iOS v 11.2 (15C114) while this iPhone is connected to my Windows 10 computer using the USB cable I get a message that says "[Filename.MOV could not be deleted. You do not have permission to delete this item" (see the screenshot).
What process can I use to delete all of the .MOV files? Can this be done through iTunes?
I currently have 99 of these files and need to delete all of them.
