What is an MVB file?

MVB files mostly belong to MathType. MVB files can mean different things depending on who created them.
An MVB file is a compressed help file. This type of file is similar to Microsoft Compiled HTML Help files and is used to package help documentation. It is often created by companies like MathType and viewed with a help viewer.
The file uses the JetDB format and is labeled as a Mobile Video Bus file. These files store bus surveillance video recordings and are used with specialized software such as Milestone XProtect Smart Client.
The file’s internal format is JFIF. Here, the MVB file holds a JPEG image, often referred to as a Multimedia Viewer Book file, that can be opened with common image programs such as Adobe Photoshop.

  • Compressed help file: Packs help documentation for fast access.
  • Mobile Video Bus: Contains surveillance video data.
  • JPEG image file: Stores viewable picture data.

How do you open MVB files?

You need a suitable software like MathType to open an MVB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MVB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MVB file directly in the browser:. Just drag the file onto this browser window and drop it.

MVB format details:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. If there are problems opening a file, you must first determine the file format used. Below you will find our evaluation of the MVB files:

MVB is seldom used as a file extension and covers different formats for different programs. The two most popular formats are as follows:
