What is an M4B (MPEG-4 Audio Layer) file?

MPEG-4 Audio Layer (M4B) is the file format that stores audiobooks and podcasts, primarily those that are available on iTunes. The cool thing about this file format is that, unlike MPEG-Audio Layer III (MP3), M4B can store digital bookmarks. This feature allows readers to pause and resume later, just like a physical bookmark in a printed book!

What is a WMV (Windows Media Video) file?

Windows Media Video (WMV) is a common and widely supported video format. It compresses the file size with a codec resulting in an easy-to-manage file that maintains the quality of the video. A digital container format, called Advanced Systems Format (ASF), often encapsulates WMV files.

How to open a WMV file?

Most media players can open and read WMV (and ASF) files. The best player for opening a WMV file is Microsoft Windows Media Player. Microsoft developed WMV and ASF, and many videos online today are WMV files. VLC media player is another reliable option, which can play multimedia files across several platforms.

WMV is also easy to convert to other video file types. However, keep in mind that the conversion process might cause picture quality to decrease. If a conversion is needed, then HandBrake is a free and open-source tool for converting WMV files.
