No, the original claim was that it "isn't necessarily a strict tree", not that it was a forest. Why is a problem? I can turn a forest into a tree by adding a base and links to the base of each subtree; a Unix file system can be viewed as a forest if you prohibit cd'ing to the root. The difference between C:\ and /C isn't that much. -- David Starner - dstarner98@aasaa.ofe.org Pointless website: http://dvdeug.dhis.org "I don't care if Bill personally has my name and reads my email and laughs at me.
