I for one would like them changed. Every company's file system that I've worked in is a fricken mess, often 8 or more levels deep. Trees more than 4 levels deep are a yellow alert. I would much rather have a relational system, or at least one based on set theory. However, those are harder to teach to non-techies, so we are stuck with trees: simple, but not powerful.

We don't know that they are files. They are files when they are downloaded locally, but perhaps they are stored in a RDB on the web server side. I've programmed dynamically generated spreadsheets before. They become files on the client side, but were dynamically generated and thus never an actual file on the server (unless maybe in the buffer, but that is not visable to us).
