Robocopy - sync folder with smartphone's internal memory

I want to keep local folder in sync with one on my smartphone's internal memory folder using robocopy. In Windows Explorer the path to destination folder looks like this:

Code:

Computer\OnePlus One\Internal memory\Music

But that did not work with robocopy resulting in creating

Code:

path_to_robocopy_sync_batch_file\Computer\OnePlus One\Internal memory\Music

Can this be done with this method?

 

Ok, could it be done with the help of any other non-command line tool called from the command prompt? Any ideas which one?
