Abstract
A file system and method serves to create and manage content. The file system includes at least one directory having at least one file containing data, but about which at least one file has no information. A repository of metadata provides information about the data in the files. Phantom files are created which are designated by names and associated attributes, point to data in base files, without specifying a path name to the base files.
