Microsoft Advanced Streaming Redirector Format | Microsoft | Video Files |
The .ASX file extension is a specialized type of XML-based playlist file developed by Microsoft Corporation. This particular file format is used by Windows Media for its Advanced Streaming Redirector (ASX) protocol. This protocol allows for streaming media across the Internet by using the HTTP protocol.
Purpose and Functionality
The ASX file format specifies a playlist of media that you can use to share audio or video files over the Internet. It also provides multiple streaming hosts, as well as other extended features such as: content labeling, event driven scripts and programmable URLs. Each item in the playlist is identified with a Universally Unique Identifier (UUID) tag, which helps to keep track of the list items. Other file types that use the same playlist functionality include: m3u,.wpl,.m3u8.
Compatibility and Usability
The.ASX format is compatible with many popular Windows-based multimedia players, including Windows Media Player, RealPlayer, QuickTime, iTunes and VLC media player. It supports both.wma and.wmv audio/video streaming formats, allowing for playback from any device that is equipped with a current version of any of these players. These playlist files are often used for publishing music and video streams over the web.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .ASX) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .ASX extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .ASX file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .ASX extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .ASX extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .ASX file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .ASX file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .ASX file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .ASX file) will be extended to the maximum.
It is also good to check
- if the .ASX file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
