I guess you mean FaccII. It's a kind of disk-buffer. But it's quite smart.
It doesn't remember all junk you run, only the most used and shortest
one. And if you take directory of your disk many times, it starts to 
remember it too, so when you write ls or dir or something, there is no
movement in disk-drive at all, directory just comes up. There should be
an utility called Facction. You can control the size of the buffer
with it. FaccII is very useful utility, if you have A LOT of memory,
but like I have only one meg, it's too little for using FaccII for anything
reasonable.
