Batch File XCOPY command?

I need to load software from a flash drive onto the desktop relatively fast (plug in, plug out fast) on about 15-20 computers.

I have looked up XCOPY batch file commands, and it seems to depend on set file locations, even though different laptops assign flash drives to different drives (some E:\, some F:\, my desktop is L:\) so I was wondering if I could get a file location relative to my batch file.

here is my script:

ECHO OFF

CLS

:MENU

ECHO.

ECHO .........

ECHO Press 1 to continue, 2 to exit

ECHO .........

ECHO.

ECHO 1 - Copy Files from Flash

ECHO 2 - EXIT

ECHO.

SET /P M=Type 1 or 2, then press ENTER:

IF %M%==1 GOTO COPY

IF %M%==2 GOTO EOF

:COPY

XCOPY "\Copy\*.*" "%userprofile%\Desktop\VGDC"

GOTO EOF

thanks in advance
