Passport Ultra -How to delete files that were moved

OK  I figured it out.  Yu have to delete the original save files in Pasport that have the lines through them.  Click on My PC, then My Passport.  The Open up WD SmartWare.swstor and open on the sub-folder that’s the name for your machine.  You’ll see the Volume in the Pasport memory.  delete the files you want to that have the line through them.  That will open space in your Passport.  I cannot guarantee that will not cause problems.  But it seems to work as I just halved the amount of space Passport was using by deleting duplicate files.
