A bad combination. Why to use it? Because you need that XML. What can happens? Ugly thinks. Like what was happening to me: after executing this command in my XML there was a new character (that SUB), visible only in special editors:

The result is an invalid XML file. Untill now it was ok, this batch was working coreclty so it is posible that my computer has received some viruses or something goes wrong with my Windows. I didn't find the answer!

The solution is ... to not use copy; there is xcopy ms-dos command or robocopy [I didn't used it yet].

To simplify the work with batch files you can use some pseudo-functions to not write one code two times. Here is a sample to prove this:

@echo off

rem call function...
call:myDosFunc 2 2
rem call again...
call:myDosFunc 3 4

echo.&pause&goto:eof


:myDosFunc
echo this is param %~1
echo this is param %~2.
goto:eof

When you use this you have to be carefully to not generate spagheti code; this options is also a posibility to get this programming problem.

In this moment you can go to your folder, right click > properties > security tab, check if your user is in the list, add it if this is necesary, and edit it rights. I hope that it works and for you
