What is an MB file?

MB files mostly belong to Maya by Autodesk. 3D scenes created with Maya and saved using Maya's binary format have MB filename extension. Such MB files contain 3D data such as scenes, worlds, textures, animation, terrains, settings, and effects such as fogs and lighting all of which are saved in binary format instead of Maya's ASCII text (MA) format. MB file extension is also associated with binary data files used by Mathematica, a program for computing and visualizing mathematical problems. MapBasic, a BASIC programming language IDE uses MB files to store custom applications and functions for MapInfo Professional Geographical Information System. Paradox, a relational database management system that is bundled with some versions of WordPerfect stores memo field values of its databases in MB files. EasyShare, a program that ships with some models of Kodak digital cameras stores its thumbnail cache using MB file extension.

How to open MB files

You need a suitable software like Maya to open an MB 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 MB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MB file directly in the browser:. Just drag the file onto this browser window and drop it.

MB file format details:

The file format determines how the data is stored in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our analysis of the MB files produces the following result:

The MB file extension is quite common and mainly uses a defined MB format. The two most popular formats are as follows:

How to solve problems with MB files

Associate the MB file extension with the correct application.
Update your software that should actually open binary 3d scenes. Because only the current version supports the latest MB file format. Search, therefore, e.g. on the Autodesk manufacturer website after an available Maya update.
To make sure that your MB file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
