Windows cannot open M4B files?

If Windows is unable to open file extension .M4B you may have registry related errors or may not have the appropriate program installed. We strongly recommend that you run a free registry scan.

Appropriate program:

The .M4B file extension identifies MPEG-4 Audio files. M4A files are used to store the audio content accompanying movies and are specialized for storing speech (as opposed to music). M4B files are essentially the same as .M4A files, and are designed to save audio books which can then be downloaded from the Internet and played back using the Microsoft Windows Media Player or Apple iTunes. The main difference between a .M4A file and a M4B file is that .M4B files can be "bookmarked.". Incorrect associations are the cause of many file extension errors. Scan your system to prevent, identify and repair M4B file extension association errors.
