Notes about the BMB file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The BMB file type is primarily associated with 'Pro/ENGINEER' by PTC. Pro/ENGINEER is a 3D product design product, featuring productivity tools that promote best practices in design while ensuring compliance with your industry and company standards. These files appear and disappear at various times when using Pro/ENGINEER. They are part of what PTC collectively calls "turd" files and the display of them in the program can be turned off in the options.
