Notes about the BFS 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 BFS file type is primarily associated with 'Tivoli Storage Manager' by IBM. The IBM Tivoli Storage Manager family of offerings is designed to provide centralized, automated data protection that can help reduce the risks associated with data loss.
