Replace already existing file – disabled notification by mistake. Cannot find where to enable

Dear WinSCP,

You know - when uploading file and if it already exists – default is alert to confirm replacement.

By mistake I clicked "Never confirm" like and files are now replacing without Confirm alert.

Where can I enable Confirm alert again?

Please, help me.

Regards,
Oleg
