In my testing it seemed to work if I added "%comspec% /c " to the start of the system command e.g.
q)system"%comspec% /c robocopy /move test\\ D:\\test"
To explain this a little, this is essentially invoking the windows command interpreter with the /c argument to supply a command to be executed immediately. In other words, it's running robocopy from within a child cmd.exe process, where it appears to work fine
Hope that helps
