In photoshop I keep getting these messages saying that I can't open a file or a picture because 'the scratch disks are full'. I thought this might mean like my memory (RAM I guess)so I tried clkosing everything that was open in the taskbar except things I need and had only IE and Photshop open. It kept giving me the same message. WHat does it mena? By the way my computer has 256 ram.
