Is there an option to not duplicate the same files on a wd cloud external drive?

I have a wd cloud external drive and I have large amounts of music that I store.  How do I not duplicate the same music or files when I drag them to the WD cloud?

Thanks

If you are dragging and dropping the files to the same share and the same song or album comes up you should see the following, see image below.

When using SmartWare, Category backup, for a different share I do not select Music to upload again. See image below.
