Consider: A repository with all files in a single directory in the top level is going to have identical probabilities of collision either way. A less special case of a repository that typically has files added to it in a particular directory (\"inbox\", say), is again going to have identical probabilities of collision. + +If you're worried about such collisions, you should not be using WORM.
