There are 3 file types use the .LXF file extension:
1. LEGO Digital Designer Model File
An LXF file is a 3D model created by LEGO Digital Designer (LDD), a program used to construct virtual LEGO models. It is saved in a compressed .ZIP format and contains two files: IMAGE100.PNG (a .PNG design preview) and IMAGE100.LXFML (an .LXFML design file, written in XML).
You can open an LXF file in LEGO Digital Designer (Windows, Mac). To do so, open LEGO Digital Designer and selectfrom the program's menu bar. Then, navigate to and open your LXF file.
How do I create a building guide for my LXF file?
To create a building guide for an LXF file, open the file in LEGO Digital Designer and then selectfrom the program's menu bar. This will create a building guide you can view in LEGO Digital Designer.

2. LEN Exchange Format File
File created in the LEN Exchange Format (LEN), a format used for exchanging swimming data (also referred to as the "Lenex" format); contains swimming event data that allows competition organization and record keeping; helps to facilitate the exchange of data between race organizers, swimming clubs, and associations.
LXF files are actually .ZIP files that contain a compressed .LEF file. An LEF file stores the actual swimming exchange data in an XML format. If you want to view the raw data, you should decompress the LXF file and then open the LEF file with a text or XML viewer.

3. Harris/Leitch Video File
An LXF file contains standard or high definition MPEG-2 video wrapped in the proprietary Leitch Native Stream Format (LXF) used by Harris Nexio media servers. It is commonly used to store a television show that is made available to a network via the Harris Nexio media server.
You will most likely only encounter LXF files if you work in the broadcasting industry and utilize the Harris Nexio media server to make videos available over some type of network. You may also receive an LXF video file that was stored on a Harris Nexio media server but you are now looking to play it on a different platform.
Since LXF files are saved in an uncommon proprietary format, few players are available that support the format.
However, you can convert LXF video to another more common format with the cross-platform FFmpeg utility. Keep in mind that FFmpeg is a program with a command-line interface that may be difficult to use depending on your computer literacy. Also, there may be a substantial loss of video quality after converting it to a different format.
