Abstract
A file management system comprises a computerized data storage and retrieval utility for integrating data files produced by independent data processing operations by linking the data files according to user-definable relationships. The machine assigns user-definable attributes to the data files and their links and searches for groups of files and links having selected attributes. The machine also maintains an archive of versions of data files and their links referenced according to their creation time. The machine includes provisions for transmitting commands to a computer operating system when selected files are accessed or modified to invoke execution of user created programs.
