WD My Book Essential delete the backup


i would to delete the backup created for category on my My Book Essential without format it.

There is something to do with the Smartware software?

You mean that you would like to delete the category backup that Smartware created without formatting the My Book? If so just explore your My book and inside it you will see a folder with the name Smartware.swstor, so chk that folder and delete it if you don’t need the backup.
