I find the claim that nobody understands multi-level file systems a hard to swallow. Inside my Documents folder, I have a folder for one of each of several organizations I work with, inside of those a set of folders for one of several different things I do for those organizations, and within some of those, a folder for every project I have going on. I don't necessarily need to know the complete path to everything, but anyone can generally look at the directory listing and see what the next directory to look into is.
