>Could someone from IBM please expand the acronyms AFS and DFS?

There is excellent documentation, and whitepapers, which fully explain
these file systems at http://www.transarc.com (look especially under
Library).

Basically, AFS is a "worldwide" file system, and DFS is like the
"next generation" of it, being part of the OSF Distributed Computing
Environment (DCE).  DFS is the Next Great Thing, so it is worth
investigating.             Richard Sims, BU
