After comparing 2 folders, how can FreeFileSync delete all duplicates in Folder 2?

Folders 1 ∩ 2 ≠ ∅, but Folder 1 ≠ Folder 2. Please list the steps to the question in the Subject Line above.

I don't know how to accomplish this, because the result 'Item exists on LEFT side only' has no option under it to 'Delete RIGHT Item'. Conversely, 'Item exists on RIGHT side only' doesn't let you 'Delete LEFT Item'.

This is not possible with FFS. You need a duplicate finder
