Abstract
A method and apparatus for storing files on a computer file storage device. The files are organized into an hierarchical directory structure. The directory structure comprises directory entries and file entries. The file entries and directory each contain a primary and a secondary pointer. The secondary pointer is initially set to a predefined value. When an entry is to be updated, the secondary pointer is overridden with a value that points to the superseding entry. This directory structure is especially suitable to be used in a write-once computer memory.
