Copy after Drag and Drop

Using version 4.2.7 (Build 758). When I drag and drop a file from the remote directory to my local directory, the system shows a dialog window, if this file already exists in my local directory, which it is right, but If I change the name and this other also exist in my directory file, this time(the secod one) the system does not ask for this confirmation, but just overwrite my existing file. It would be better that each instance of overwritting should be confirmed.

Do you mean when you use the "New name" button on the overwrite conformation prompt?
