I'm writing a small batch file to replace users' themes and charts in Office and I have the below batch file that works just fine.

cd c:\documents and settings\%username%\application data\microsoft\templates

echo Y|rmdir charts /s

mkdir charts

echo Y|del "c:\documents and settings\%username%\application data\microsoft\templates\document themes\*.*"

net use o: \\servername\sms

copy "o:\ppt themes\charts\*.*" "c:\documents and settings\%username%\application data\microsoft\templates\charts"

copy "o:\ppt themes\Document Themes\*.*" "c:\documents and settings\%username%\application data\microsoft\templates\document themes"

c:

net use o: /delete

Now what I want is the above to only run if it hasn't run before as we'll be pushing this out to all users for around 2 weeks to catch people that aren't in every day.

Is there any way to begin the command with something to look for one of the new themes/charts already pushed down, and if it's present, then have it not run?

Any help on this would be greatly appreciated as I'm pretty new to these batch files.
