The application manages the files and folder stuff for you, while you only get displayed a structure more useful in the project case. I do agree that this is not a meta file system, more like a plug on top of current file systems, despite it is an approach to test what kind of information users really depend on. If we know how people react on information structured like real world examples we can start up to build computers for consumers without forcing our mindsets on them and not for programmers anymore. The prove that this can be a track record is provided by the object orientation.
