File extension .M4B

File description

M4B files are Audio Book files. They are similar to M4A files but are specified for audio books. In addition to audio, the M4B file supports metadata for chapter selection and bookmarking. The M4B file usually uses some type of AAC or Advanced Audio Codec.

The M4B standard falls under the MPEG-4 Part 14 digital multimedia format specification. Other MPEG-4 file standards can use chapters, images, and hyperlinks, but M4B can further ‘bookmark’ an audio location. Remembering the last listening spot is an important feature of the Audio Book format.

Remember that you need to download a program to support a particular file type. So first look through the entire contents of the website to select a program to support just the file you have.

Other possible reasons why your .M4B file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .M4B file, there may be several reasons that cause problems with opening and operation of the data format:

1. Incorrect version of the installed application

A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .M4B file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .M4B file, so download the update and check again.

2. Incorrect .M4B file association with the program

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:

Right-click the .M4B file
Go to the "Open with" - then "Choose default program ..."
Locate the appropriate application
Click "OK"

3. The file is corrupt

It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
