MACROMEDIA DIRECTOR MX-USING DIRECTOR MX Use Manual page 573

The Shockwave player includes the Xtra extensions that support the most common features and
media types. These include text; vector shapes; Macromedia Flash; BMP, PICT, JPEG, and GIF
file importing; sound management; and Shockwave Audio.
Xtra extensions not included with the Shockwave player must be installed in a user's system before
the movie plays. Use the Download If Needed option in the Movie Xtras dialog box to make the
movie prompt the user to download the Xtra extension. Director downloads Xtra extensions from
the URL specified in the Xtrainfo.txt file in the Director application folder.
Xtra extensions downloading from projectors requires use of Lingo. See
Lingo Dictionary.
Xtrainfo.txt includes URLs for all Macromedia Xtra extensions included with Director, but you
may need to manually edit Xtrainfo.txt to add the URL for third-party Xtra extensions or
Macromedia Xtra extensions not included with Director. Xtrainfo.txt includes a description of
how to enter this information. Xtra developers may also provide installation programs or other
means of modifying Xtrainfo.txt automatically.
If a user chooses to download an Xtra extension, Director retrieves the Xtra extension from the
URL specified in Xtrainfo.txt using the Verisign download security system. Verisign is a standard
means of downloading software from secure sources. For more information on making Xtra
extensions secure for download, see "Using the Xtra Packaging Kit" in the Xtras Support Center
of the Macromedia website at www.macromedia.com/support/xtras/info/packaging/
contents.html.
You can also include Xtra extensions in projector files. Select the Include in Projector option in
the Movie Xtras dialog box for any Xtra extension you want to include.
