The Advanced Stream Redirector (ASX) format is a type of XML metafile designed to store a playlist of Windows Media files for a multimedia presentation.

It is used frequently on streaming video servers where multiple ASF files are to be played in succession. Both RTSP and MMS streaming protocols are supported, as well as HTTP.

ASX files have MIME type video/x-ms-asf (as do ASF files).

With the introduction of the WMA and WMV container formats in late 1990s, WAX and WVX extensions have also been introduced by Microsoft respectively.
