My understanding of zero knowledge proof is basically an algorithm to
prove you have data (a password, an answer to a complex question, an
account number, etc. ) without revealing anything useful about the number.
Sometimes refered to as minimal disclosure.  Quite handy to prove for
instance that you have a password, without revealing the plaintext to
whoever is challanging your possession of said password.

I've no idea how that (or related ideas) would apply usefully to a
filesystem.
