General :: Batch File To Allow Users To Copy Latest Version Of Front End Whenever Change Made

I have been trying to set up a batch file to allow users to copy the latest version of the front end whenever a change is made. The following is the code that I am trying to get to work properly. The first part works fine, the old front end is copied to a folder on the user's desktop as a backup. But I cannot get the copy of the server - the "P" drive, to overwrite the current copy on the user's desktop. Actually I cannot get the code to copy the new front end from the server and install it on the user's desktop. I think the path is correct for I seem to be able to run the new front end from the server.

When I look for the location on my computer, the server locations is listed as:

General (Servernamefiles) (P: ) (there is no space after the P: it seems to result in a smiley face when I type it and try to post it).

for /f "tokens=2-4 delims=/ " %%a in ('date /T') do set year=%%c
for /f "tokens=2-4 delims=/ " %%a in ('date /T') do set month=%%a
for /f "tokens=2-4 delims=/ " %%a in ('date /T') do set day=%%b
set TODAY=%year%-%month%-%day%
rem echo %TODAY%

[Code] .....

This code works so I thought that the path was correct
rem this works
rem start the new DB front end
Start P:AccessMainSplitBENewFrontEndDBMain.accdb

But this code does not.
echo f | xcopy /f/y/ P:AccessMainSplitBENewFrontEndDBMain.accdb c:UsersUserNameDesktopDBMain.accdb

Neither does this:
echo f | xcopy /f/y/ ServerNamefilesP:AccessMainSplitBENewFrontEn dDBMain.accdb c:UsersUserNameDesktopDBMain.accdb
