MIME Map
Use the MIME Map property sheet to configure Multipurpose Internet Mail Extensions (MIME) mappings. These mappings set the various file types that the Web service returns to browsers. The registered file types that are installed by default on Windows NT are listed in the Registered file types dialog box.
To configure MIME mappings, click the New Type button. In the File Type dialog box enter the extension that is associated with the file in the Associated Extension box. In the Content Type (MIME) box enter the MIME type followed by the filename extension in the form <mime type> / <filename extension>.
To remove MIME mappings, select the file type in the Registered file types box and click the Remove button.
If you set MIME mappings in the master property sheets for your computer, the Web sites and directories on your computer use the same mappings. You can modify the MIME mappings for a Web site or directory. The only values displayed are those you changed, and not all the MIME mapping values. If you then reapply the master properties, the master properties completely replace the modified properties for the Web site or directory. That is, the properties are not merged.
