Sincronize and delete files on TARGET subdirectories only for folders/directories off the SOURCE

Sorry my English.

I would like an option to
delete files in the TARGET
(that do not exist in SOURCE)
only for the same FOLDERS name
on the SOURCE.

It's a merge deleting for existing directories in both side, deleting sub-directories and files that are not anymore in SOURCE.

I see that there is an option, but if I use it, it 'll delete the others directories in TARGET root.

Do I understand right that you want to delete orphan files, but not orphan folders?

Cannot you just exclude the orphan folders from synchronization?
