I will point out that there are legitimate reasons to avoid doing a "move" from camera card to computer. I will also point out that not everyone agrees.
The reasons you might want to avoid doing a "move" from a camera card is that if you have any type of problem — power outage, other glitch, corruption of photo (which happens when a card reader goes bad or USB cable goes bad or hard disk goes bad, just read these forums to see many many many many many many examples) — then you have no photo on the camera card and either no photo on the hard disk or a corrupted photo on the hard disk.
