Subject  :  The /Z and /RX switches
Size(KB) :  1


XXCOPY has some other switches that I wondered about as I read them. For
example, the effect of the /Z switch has been described as something like
"deletes extra files/directories in the destination".

I wondered, just what is considered to be an "extra file" in the
destination?

Just to give a clear example - what would be the effect of:

xxcopy c:\src\*.doc c:\dst\ /ZY

Two possibilities:

(1) All the files in c:\dst, besides the .doc files copied over from c:\src,
are "extra" files and are deleted.

(2) Only the *.doc files in c:\dst that are not in c:\src are extra files
and are deleted.

The answer is (2) - only those files in the destination which fit the source
file selection criteria (here *.doc), and which are not in the source
directory, will be deleted. (Maybe Kan could describe this
better.)

The technical bulletin recommend that instead of using /Z or /RX (Remove
Extra) switches, it can be better to switch the source and destination
directories and use /RS/BB instead, so that the files will be deleted from
the source directory instead of the destination directory. In this case,
the following could be used in place of the above command line:

xxcopy c:\dst\*.doc c:\src\ /RS/BB

This command line also has the effect of deleting from c:\dst the *.doc
files that are not also in c:\src.
