F.ex: HD (BWF or PPM) -> RAM (RLE) -> CACHE Actually I can't imagine what your "BWF" is supposed to mean. :-( I do know however that arithmic coding fed by context models is [BLEEP]ing slow. Particularly the decompressing, compared to LZ style decompression. Without dedicated hardware it will not be the way to go re: hard disk compression. And to make things worse: context modeling did not beat LZ in many experiments with 5-men data. Which is quite annoting since it does look like the ultimate algorithm. ... Johan
