The bbw file extension is associated with the 2007 version of Band-in-a-Box for Microsoft Windows. Band-in-a-Box is music composition software from PG Music and is available on multiple platforms.
Band-in-a-Box creates a bbw file when it starts and uses the file to store interface settings. It is supporting data for the application, not a song, style, or other musical project file.
Open the bbw file with Band-in-a-Box on the system where it is stored. The application normally reads this interface data automatically when it starts, so the file may not be intended for direct opening through an Open command.
Because the file contains application settings rather than musical content, do not expect it to open as a song or project.
A bbw file is not a conventional music or document file, so it cannot be meaningfully converted to another format. Band-in-a-Box uses it as interface data rather than as an exportable composition.
