One of the most widely replicated UX results is that over half of people don't "get" the concept of a nested directory structure. Not even when you try to explain it to them. Not dumb people either. College graduates. It seems to be a mental block. I have never heard of this ("most widely replicated UX result"), nor have I ever seen it to be the case on any kind of consistent basis. In an effort to perform a minimum of due diligence, I ran a couple web searches and no relevant articles were returned. What I do believe, is that users have difficulty understanding directories / folders as they can be represented on newer OS's as another commenter very eloquently pointed out. However, I am highly skeptical of the claim that the population at large is simply unable to grasp the basic concept of hierarchical directories.
