Run BAT file at shutdown to synch directories across drives

[Xanadu3141]

I have created a txt file called SYNC.TXT that looks like:
load C:\Users\XXX\AppData\Roaming\Mozilla D:\UTILITIES\WINDOWSMGMT\BKUP\Mozilla
sync create-empty mirror:left->right

I have created a BAT called SYNC.BAT that looks like:

"C:\Program Files\Beyond Compare 4\BCompare.exe" @D:\UTILITIES\WINDOWSMGMT\SOFTWARE\BATCH\SYNCH.TXT

I cannot get the BAT file to work when I run it as an Administrator.

However, if I open an Administrator command prompt and run "C:\Program Files\Beyond Compare 4\BCompare.exe" @D:\UTILITIES\WINDOWSMGMT\SOFTWARE\BATCH\SYNCH.TXT
I have no problems.

What I want to do is assign the BAT file using the Group Policy Editor to Computer Configuration ==> Windows Settings ==> Scripts ==> Shutdown so that it will run and sync the Mozilla directory on the “C” drive with a folder on the “D” drive when I shut down my computer.

What am I doing wrong?
Thanks.

OK - found it. MY fault - I had an embedded blank in a directory name to make it sort to the top of a list.
