File extension .LSX
Full Name | Developer | Category |
---|---|---|
Advanced Streaming Redirector Format | Microsoft | Video Files |
The .LSX file extension is associated with streaming media shortcuts used in Microsoft Windows Media Player. LSX files are used to store links to streaming media, such as audio and video files in the ASF (Advanced Streaming Format) format. When clicked, the LSX shortcut will link to the original media file stored on the user’s hard drive, or on a server located elsewhere, enabling the user to access and play the content within Windows Media Player. RL2 files are a later version of LSX, and while RL2 shortcuts can be interpreted by earlier versions of Windows Media Player, LSX shortcuts cannot be read by later versions of the program.

Other similar file extensions also relate to streaming media shortcuts, including .LSF, .ASX, WLO, and WSX.
Opening LSX Files
Microsoft Windows Media Player is the main software application for opening and playing LSX files on Windows. The software can also be used to create LSX shortcuts by selecting “File > Create Shortcut” from within the program. The associated shortcut links will open with Windows Media Player 11 if the player is installed on the user’s computer. Unable to open an LSX file? Check the file’s extension in order to determine the software that can be used to open it. For example, an.LSX file may open differently depending its content type and version – some older versions of Windows Media Player can actually play LSX files natively without any additional software installed.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .LSX) 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 .LSX 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 .LSX 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 .LSX 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 .LSX extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .LSX file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .LSX 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 .LSX file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .LSX file) will be extended to the maximum.
It is also good to check
- if the .LSX file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
