What is a BUD file?

BUD files mostly belong to Canon Firmware Updater. BUD files are not a single type of file. They can be used in different systems to store binary data.

Printer Firmware / Embroidery Data: Some BUD files are used in printer firmware updates by Canon and for embroidery data by Brother systems. These files hold coded instructions for device function. Refer to Canon's webpage for more details.

Game Data Container: Other BUD files act as a container for game assets. They store data that a game engine (such as those related to Unreal projects) uses to load resources. Tools like Dragon UnPACKer can help manage these files.

Backup Archive: A third group of BUD files comes in a compressed format (using GZIP) and is used for backup purposes. They are created by backup utilities (for example, BuddyBackup) to hold archived data.

FilExt.com note: The file structure and internal format will differ with each use. Finding the right tool to open or view the file depends on its origin.
