> Our algorithm to hash folders produces hashes 160bits long. Which means that 2^160 -1 different folders can be securely hashed!
Except that's even more wrong. Collisions are expected long before 2^160 - 1 hashes.

It would seem that consideration was put in to defending against collision attacks.
