If you are saying you want to delete them directly from your memory card without using the camera, you are playing with fire. The FAT corruption demon is just waiting in the shadows for you.
Seriously, copy from the card to a harddrive and ALWAYS reformat the card when you first put it back in the camera.
In other words only allow the camera (and that's one camera model too) to write to or delete from the memory card.
I agree completely with Festina.... Copy pictures to a file on computer, and then format card in the camera, not the computer.
