Filter Button in the Open Window

  Click on the Filter button if you modify the file extension
  in the Filter entry box.  A list of files with the desired file
  extension will appear in the Files list box.  If there are no files
  that match the file filter specification, no files will appear in
  the list box.

  You must modify the Filter entry box as directed if either of
  the following conditions is true:

  -   The file is located on a node other than the node where
      you are logged in.  In this case, modify the beginning of
      the Filter entry box to include the correct node.

      Note that if you change the node specification, be sure
      to check the directory specification.  The Filter entry box
      must not refer to a directory that does not exist or cannot
      be accessed on the specified node.

  -   The file name does not include the default extension for
      the specified format.  (The default extension appears in
      the Filter entry box when you click on the format name.)
      In this case, modify the end of the Filter entry box to
      include the extension actually used in the file name.

  After modifying the Filter entry box, click on Filter (or press
  RETURN). If you changed the node specification, double click
  on the correct directory name.  Then select the desired format
  and file name.
