The best compression I have seen is 9GB into 1.8GB, But I do not think it is possible for 4GB to be compressed into 2.28MB - Are you sure its not being read wrong by the computer or edited by someone to make it think its 2.28MB?
Because mds doesn't really compress at all, it just makes a 100% copy
I recently acquired a 2.28 MB mdf (with a 4KB mds) that I expected to contain several megabyte's worth of game maps. So I decided to mount them in Daemon Tools. To my great astonishment, the contents of the mdf amounted to over 4GB!
How can this be possible? I've verified that the files are indeed of such great proportions by copying some of them to my HD and opening them successfully. Is there some magic compression method behind the mdf format??
I'm delightlfuly baffled at having discovered this. Could someone be so kind as to give me an explanation?
