Notes about the KBN 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 KBN file type is primarily associated with 'TeamSpeak' by TeamSpeak Systems. TeamSpeak is a scalable application which enables people to speak with one another over the Internet. TeamSpeak consists of both client and server software. The server acts as a host to multiple client connections, capable of handling many simultaneous users.
