Normally you can use . to reference the current directory, but this won't work:
Copy MOVE . TO G:\
It won't work because the command is running from the current directory, which means the directory is locked and cannot be moved.
To make it work you have to change to another directory, after which you can't use . anymore since . is something else, but you can use {sourcepath} instead:
cd ..
dopusrt /cmd Copy MOVE "{sourcepath}" TO "c:\temp\2\1"
I'm not sure if you need the "dopusrt /cmd" part or not.
