What is a NBD file?
A .NBD file is a data container used primarily for system backups or video game assets. Because different developers use this extension, a .NBD file can have several different internal structures.
Most often, it is a backup archive created by Nero BackItUp to store copies of entire hard drives. It can also be a Data Backup Data File created by software from Prosoft Engineering, or a similar backup file from NovaStor. In the video game industry, a .NBD file contains 3D models and textures used by the Capcom MT Framework engine.
How to open NBD files?
You cannot open .NBD files with standard operating system tools. Because the .NBD extension has multiple possible meanings, you must first know which application created it. Double-clicking the file will usually result in an error. If it is a system backup, you need the matching recovery software, such as Nero BackItUp or the Prosoft Engineering recovery tool. If it is a game asset, you need specialized modding utilities designed for Capcom games to view the 3D models.
