The Andrew File System is a distributed file system developed by Carnegie Mellon University

The Andrew File System (AFS) is a distributed file system. It uses a set of servers to store files, and has aggressive caching on the client to improve performance.

It uses Kerberos for authentication. The permissions system is richer than the usual UNIX permissions model, as files can have arbitrary access control lists associated with them.
