NCSA Mosaic for MS Windows User Guide: Customizing

Viewers

Use this dialog box to configure your external viewers.

Each file sent from a Web server is associated with a MIME (Multipurpose Internet Mail Extension) type (see "Setting Up Mosaic Viewers" on page D-1). NCSA Mosaic doesn't handle every file type (e.g., PostScript or .ps, movies or .mpeg, documents or .doc). However, Mosaic can send these files to an external application (called an external viewer) if the file's MIME type is associated with appropriate viewer software in the Viewers Preferences dialog box. This external application is opened by Mosaic to handle the file type sent from the server.

The following fields can be edited but do so with caution. If you have problems with a MIME/Viewer configuration, check the appropriate MIME type for type errors. Editing the information in these fields changes your current viewer configuration.
