US Patent 7386532 System and method for managing versions

A system and method for electronic file management includes an object-oriented file management database, a volume manager, and a coherency manager. The volume manager manages electronic files and metadata relating to the files of one or more volumes. Each volume may include folders, files, and/or other digital content. The file management system may also automatically manage versions of electronic files. This version management may be based on opening, saving, and changing of files. A user interface facilitates user interaction with the file management system. The user interface may enable a user to view, within the file management system, one or more versions of the electronic files.
