Support General support is available through HelpSU. Overview AFS Andrew File Sercices is a distributed, networked file system that enables efficient file sharing between clients and servers. It only contains temporary files needed for workstation initialization and symbolic links to files in the shared name space. Once created, users of the filesystem may create directories and files as usual without concern for the physical location of the volume.
A fourth implementation exists in the Linux kernel source code since at least version 2. The AFS command suite guarantees that all read-only volumes contain exact copies of the original read-write volume at the time the read-only copy was created. Volumes are created by administrators and linked at a specific named path in an AFS cell.
File and Data Storage: AFS version two is also the predecessor of the Coda file system.

AFS Andrew Dietributed System is a distributed, networked file system that enables efficient file sharing between clients and servers. As needed, AFS administrators can move that volume to another server and disk location without the need to notify users; indeed, the operation can occur while files in that volume are being used. The file name space on an Andrew workstation is partitioned into a shared and local name space.
The Andrew File System AFS  is a distributed file system which uses a set of trusted servers to present a homogeneous, location-transparent file name space to all the client workstations.
