Windows 8.1 command line batch file burn bluray dvd

I am archiving a large number of zip files on BluRay DVDs.

When I use file explorer to drag and drop the process works fine but when I create a batch file (like the one attached) the process is VERY SLOW

Batch file command I tried:

Copy w:\zzz\zip-bak\daybkup\ g:\

I tried

isoburn g:\ w:\zzz\zip-bak\daybkup\

But it pops up with a prompt each time

I have tried formatting the BluRay DVD as a DVD, a USB, and using the Windows format command

Is there a better command to use in a batch file

Seems to want to copy the whole directory

robocopy w:\zzz\zip-bak\daybkup\ g:\

yields an error see attached file
Wrong syntax, use
robocopy w:\zzz\zip-bak\daybkup\ g:\
