Kan, I must admit I was similarly confused by Bob's question until 
his most recent post. What he is referring to is that Xxcopy will 
always create the destination base directory even when the are NO 
files to be copied.

Take a simple example. There are no d:\temp\*.xyz files and the 
directory d:\test\ does not exist.

D:\>xxcopy d:\temp\*.xyz d:\test\

XXCOPY == Pro Edition == Ver 2.84.0 (c)1995-2003 Pixelab, Inc.

-------------------------------------------------------------------
Directories processed = 1
Total data in bytes = 0
Elapsed time in sec. = 0.001
Action speed (MB/min) = 0
Files copied = 0
Directories created = 1 <= Note this
Exit code = 100 (No files were found to copy)

Note that Xxcopy created 1 directory (D:\test\) but no files were 
found to copy so we end up with a new empty directory.

This behaviour applies to the destination base directory but not to 
any destination sub-directories e.g. adding a /S to the previous 
command does not create any empty sub-directories of the destination 
base directory.

D:\>rd d:\test

D:\>xxcopy d:\temp\*.xyz d:\test\ /s

XXCOPY == Pro Edition == Ver 2.84.0 (c)1995-2003 Pixelab, Inc.

-------------------------------------------------------------------
Directories processed = 3
Total data in bytes = 0
Elapsed time in sec. = 0.01
Action speed (MB/min) = 0
Files copied = 0
Directories created = 1
Exit code = 100 (No files were found to copy)

Even though there are 3 directories processed (D:\temp\ + 2 sub-
directories), only the destination base directory (D:\test\) is 
created.

This behaviour appears to apply to all Xxcopy operations (except /L) 
irrespective of the file selection switches or the structure of the 
source directory. Namely, even when there are no files selected, the 
destination base directory will be created if it doesn't already 
exist.

I personally don't have a problem with this but I can see why it is 
not particularly desirable.
