How to delete unwanted file from back up automatically?

I set up the smartware for back up, my issue is that when delete some files from pc and the WD still keeps the files.

I am wondering if there’s a setting within the software that will delete those files automatically once I delete them from my pc?  Thanks in advance for any helps or suggestions!

I have the same question.  I have been using Smartware for a couple of years and there are now 700 GB backed up on the drive out of only 400 GB that are currently on my computer that I want to keep.  The only option I have found in settings was to reduce the number of back-ups per file which is unrelated.
