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.
