Yes I use all different brands of cameras, load the pictures to a folder on my lap top then select the "E" drive(or what ever you used to load the photos) click on the folder for that card and right click delete. Very simple takes 3 clicks and about 30 seconds. I've done this on different brands of laptops as well. Works the same way every time
