Abstract of the Disclosure, A method and apparatus for automatically indexing and retrieving files in large computer file systems is provided. Keywords are automatically extracted from files to be indexed and used as the entries in an index file. Each file having one of the index entries as a keyword is associated in the index with that keyword. If a file is to be retrieved, and its content but not it name or location is known, its keywards are entered and its identifying information will be displayed (along with that of other files having that keyword), facilitating its retrieval.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
