Did you find or received M4B file and your computer failed to open it? Below we will explain what is M4B file extension and how you can open it.
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.".
In most cases your computer should know what software program should be used to open different file types and extensions like M4B. When you double click on the M4B file format, it should open with appropriate software program. If you downloaded or received M4B files for the first time and your system failed to open it then try free file viewers available on the internet after doing enough research not to fall prey to malware.
