This time, still one thing puzzles me.

Above, it is stated that XXCOPY16 was used. But, the
command lines provided in the report shows XXCOPY (not XXCOPY16).
Was XXCOPY16.EXE renamed to XXCOPY.EXE and invoked
as shown in the report? While the XXCOPY programs can
be renamed and executed without a problem, it will add
confusion.

I assume renaming of XXCOPY16.EXE to XXCOPY.EXE did not
take place. Rather, XXCOPY (the 32-bit version) was run.

If this is the case, it is dangerous to use /CLONE. Maybe,
you should use /BACKUP instead.

When you are synchronizing two directories, /CLONE will
remove any files that are unique in the destination
(not found their counterpart in the source). I suppose
most people in such a situation want newly created files
in either of the two directories to be copied to the other
one rather than to be deleted from the both directories.
To do this requires /BACKUP rather than /CLONE.

First of all, if "c:\jl\longnames2003\accounts" is a directory name,
it is best if you terminate the source specifier with a backslash

E.g.,

xxcopy c:\jl\longnames2003\accounts\ g:\jl\longname2003\ /clone /DA

If "c:\jl\longnames2003\accounts" exists as a file, XXCOPY will
treat it as a file rather than a directory. Otherwise the
source specifier will be interpreted as the filename pattern
(single file per directory) which will be searched and copied
from all subdirectories in the c:\jl\longnames2003\ directory.

I don't think I provided a satisfactory answer here but then,
I don't know exactly what was intended.
