What is a MUX file

MUX files mostly belong to Kazam. MUX files are multimedia container files that store combined media streams. They are mainly used by Kazam, a tool that captures your screen and saves the video in a Matroska style container.

Kazam Screen Recordings: These files hold synchronized video and audio from your screen capture, with separate media streams multiplexed together.

ManiaPlanet Game Data: In some cases, a MUX file carries game audio and related data handled by tools like NadeoImporter.

FilExt.com tip: If playback is an issue, renaming the file extension to .mkv may allow media players like VLC to open it. For more details, visit Kazam or ManiaPlanet.

How do you open MUX files?

You need a suitable software like Kazam to open a MUX file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MUX file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MUX file directly in the browser:. Just drag the file onto this browser window and drop it.

MUX format details:

The file format determines how the data is stored in the file. The file format can be deduced from the file extension and the signature. File extension, signature and file format must match; otherwise errors will occur when the file is opened. Knowledge is power - this also applies when dealing with unknown or faulty files. Our examination of the MUX files comes to the following conclusion:

The MUX file extension is rarely used and mainly uses a special format. The two most common formats are as follows:

80% of all MUX files use the same file format, which can be identified by the letters "00 00 00 02 09 10 00 00" at the beginning. They consist of unreadable binary data. A typical file size is 210 MB. The file type is a fairly new file format. The following keywords are characteristic: x264 - core 155 r2917 0a84d98 - H.264/MPEG-4 AVC codec - Copyleft 2003-2018 - http://www.videolan.org/x264.html - options: cab and x264 - core 152 r2854 e9a5903 - H.264/MPEG-4 AVC codec - Copyleft 2003-2017 - http://www.videolan.org/x264.html - options: cab. Such MUX files store data about kazam, movie, found and math.
7% of all MUX files start with the bytes NadeoFile, which are crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. The files are on average 2 MB in size and range from 1 MB to 4 MB. The following keywords are characteristic: NadeoFile.

All other MUX files (13%) have no uniform format, often, for example, MUX video. Just click the "Choose your .mux file to analyze" button on this page to find out what your MUX file is.
