Download OpenAFS 1.5.77

AFS is a file system that originated at Carnegie Mellon University. It was subsequently further developed and published by Transarc Corporation, which in turn was acquired by IBM in the mid-1990s. In 2000, IBM released an open source version of AFS released under the catchy name OpenAFS. For more information, please refer to this page. The developers of OpenAFS released version 1.5.77 a few days ago, which is considered suitable for production environments on the Windows platform. The announcement looks like this:
