dtutil.exe Creating Folder SQL only if the folder doesn't ..

I was wonder if anyone know how I go about creating a folder in SQL location
only if the folder doesn't exist. I can create a folder if I run

dtutil.exe /SourceServer mySqlServer /FCreate SQL;/;NewFolder

However if the folder already exist, I get and error. I'm trying to write a
batch file to create the folder (only if it doesn't exist) and then copy my
package into sql server.
