What happens here is the Networker tracks the changetime of the directory 
(which will change by a deletion in the POSIX compliant setups). If changed, 
the directory info was backed up again in its new form. In Windows this has 
been a problem as Windows doesn't seem to consider a deletion of a directory a 
change :-( and that generated a problem in some versions of Networker. Should 
work fine in the more recent Networkers though.

Same thing with a unchanged but renamed file BTW.
