i only just noticed this! "Secure Move With Eraser". if you want to move something, and not leave a copy of it on your HDD, you can right-click, drag, then unclick and select - Secure Move With Eraser. the pointer in the table will be changed to the new location if it's on the same partition. if it's moved to a different medium then it will be securely erased. N.B. you need eraser installed for this to work.
