Microsoft® Windows Media™ Download packages combine borders, playlist information, and multimedia content in a single downloadable file (which has a .wmd file name extension). For example, users can download a customized WMD package from a Web site. The WMD package could include an entire album of music videos that also display advertising in the form of graphical branding and hyperlinks to an online music retailer site. After you have created the WMD package and uploaded it to a Web site, all the user has to do is click a link to it. The package is then downloaded to the user's computer, the files inside the package are extracted automatically, playlists are added to the playlists drop-down box, the content is added to the Media Library, a border appears in the Now Playing pane of the full mode Windows Media Player, and the initial item on the playlist begins playing.
