πfs – A data-free filesystem
&gt; Now, we all know that it can take a while to find a long sequence of digits in π, so for practical reasons, we should break the files up into smaller chunks that can be more readily found. In this implementation, to maximise performance, we consider each individual byte of the file separately, and look it up in π.<p>So basically like a regular filesystem except now lookup each byte every time you intend to use it?
