XXCOPY install is nothing but invoking the "XXCOPY /INSTALL"
command. If you run XXCOPY.EXE directly (as opposed to
running the INSTALL.BAT), you may run it from anywhere.
XXCOPY.EXE will figure out where it is stored and find its
companion files and copies all necessary files to the
target directory. When it finds an older verion of XXCOPY.EXE
in the target directory, it will figure out what version
it is and rename the old file with encoded version number
(e.g., XXCOPY.EXE v.1.23.4 will be renamed to XX1234.EXE)
so that you can still go back to the older version by
spelling out the renamed file.

Since some users don't read the instructions (or anything),
we provide the INSTALL.BAT file. The only problem we had
was that for the INSTALL.BAT script to work correctly,
it had to be invoked after you made the directory current.
This was the requirement we had to explain in the README.TXT
file (you probably did not read it and wasted a lot of
time as a result).

The new scheme incorporated by Garry's generous help
allow us to provide the INSTALL.BAT program which can be
invoked without making the temporary directory current.

In the future release, the installation of a new version
will be to unzip the downloaded file into a temporary
directory and double-click the INSTALL.BAT file.

Bob Weir suggested to use "unique" batch file name.
Although it avoids the name collision, it also defeats
the purpose. We have to provide a file which conforms
to the "convention" ---- the installation program should
be called "SETUP.EXE", "SETUP.BAT", "INSTALL.EXE",
"INSTALL.BAT". Although we could let the user guess
which file to invoke by looking at the file names,
we have to remember that there are many users who don't
read and who do not understand what "current directory"
means.

Yes, it will work. The conditional statement in the
new batch file was added to address the very issue
you were concerned.

You may continue to do so. If I were a regular XXCOPY
user, I would definitely keep all downloaded version
somewhere --- creating a subdirectory for each release.
