  • Patent number: 5423034
    Abstract: A file directory structure generator and retrieval tool for use in a computer network is disclosed. The computer network comprises an output device, a local memory, a shared memory, and a local processor operating according to an operating system program and an application program. The local memory and the shared memory store files in a directory structure. Each file and level in the directory structure has network access privileges. The file directory structure generator and retrieval tool has a document locator module that maps the directory structure of the files stored in the memory to a real world hierarchical file structure of files and directories independent of conventions of the operating system. The document locator module can also change the network access privileges for files and directories without exiting the application program.

  • Patent number: 5355497
    Abstract: A file directory structure and retrieval system for use in a computer that operates according to an operating system program and an application program. The memory of the computer stores files in a directory structure. A document locator module maps the directory structure of the files stored in the memory to a real world hierarchical file structure of files and directories. The mapping is independent of conventions of the operating system. The document locator module can create, move and delete files and directories without exiting the application program. An open module operates in the background of the application program and intercepts control of the processor when a command is executed to cause a file to be opened. The open module displays on the output device an open card to allow entry of information relating to the contents of the file and location of the file in the real world hierarchical file structure of the file. It causes the file to be opened.
