Need to free up space

New to the WD community.  I have a My Book Essential external HD and it has no more space for backup saying “Disk is Full”.  It shows certain % of HD are made up of photos, documents, music, etc, and then a larger % is “Additional Files”.  How do I select the files to delete from this group to free up more space?

Welcome to the Community,

Additional Files, are files that were copied to the drive without using the WD Smartware software. You should be able to access the drive manually and look for the files that you want to move to a different location.
