In the further part of this page we have added a list of programs that should open your M4B file. It is enough you choose a proper application for your operating system, download and install it.

Description

M4B refers to mp4 or m4a files that contain audiobooks, radio plays or podcasts.

iTunes and Apple's iPod have made this format popular. Your M4B files are encoded exclusively in either the lossy AAC or the lossless Apple Lossless.

The peculiarity of M4B over m4a is that the files allow bookmarks to be set so that the listener can return exactly to a previously defined point.

In general, however, M4B files can also contain audio data encoded with other compression methods. However, this is rare.

The contents of the file may also be protected by DRM (Digital Rights Management). Then you need a corresponding, possibly paid license to view the content.

Most audio players can play this format. Whether they support the possibility of bookmarks varies from case to case.

MP3 and MP4 hardware player only in exceptional cases.

How to open a M4B file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the M4B file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a M4B file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support M4B files. At this point we are looking for disk space where the application was installed in and we can link it with a M4B file. Since then, our operating system will use the selected program to support all M4B files.

Other issues

Despite the described problem with M4B there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the M4B file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the M4B file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
