Notes about the BBM file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The BBM file type is primarily associated with 'BDBZM' by Project BDBZM. [Japanese site] A widely-used file joiner in Japan. No English-language interface.
