AFS Space
AFS is a distributed file system similar to a Windows or UNIX file server that allows Windows and UNIX computers to use the same file space. Casual Windows and UNIX users will see little difference between working with files on the local hard drive and working with files stored in AFS space.
For more information about how to use AFS, please visit

AFS Space (Cont.)
Setting a AFS drive letter to a particular space – it is more like mount a directory to a drive letter, which does not represent a physical drive. Example:
If you want to access geography’ AFS space via a drive letter, first, you need to know its location in Unix - /afs/isis/depts/geog/, then create a AFS drive using this path.

AFS Space (Cont.)
Note:
You do not have to set a drive letter for a particular space every time when you login – most time, your computer will remember the mapping.
Also, most PCs managed by ITS or OASIS will map some typical AFS space automatically, such as the general AFS space /afs, or /afs/isis/depts/geog, or your personal AFS space.
