Cannot xcopy outlook.pst ?

[cyberal]

My outlook.pst file is in C:\Users\Al\My Documents\Outlook Files\Outlook.pst
I am using this command in a batch file
xcopy /E "C:\Users\Al\My Documents\Outlook Files\Outlook.pst" "G:\4-Als-Email\outlook.pst" and it keeps telling me that outlook.pst is "not found"
I tried if exist "C:\Users\Al\My Documents\Outlook Files\outlook.pst" and it finds the file
Is there something preventing me from copying the .pst file?
I would appreciate any help you can give me on this.

DenotsNiaga,
Thanks much for your reply. Outlook was not open but I figured out that the external drive that I was trying to copy to could not handle the 6GB file size. It has the old file system on it I presume which limits it to 2GB I think. At any rate, when I copied it to the drive on my PC, it worked fine.
Thanks again for your response
