missing overwrite confirmation

I'm interested if there is an option to ensure confirmation when drag&dropping inside local panel?
In my experience (I've just updated to latest non-beta, 4.1.8, when I drop a local folder in another local folder, which contains folder with the same name (and also files with the same name), destination is overwritten withoit any confirmation.
I've searched this forum and tried with preferences - with no success...
