Cancels deletion of messages from the server

Dear Sirs, I have noticed that in previous versions of the program when exporting and uploading the website after clicking on "Export website to the Internet" was displayed another page where you could still change the location of the page content, or a very good function to delete the previous site content. I didn't find this option in the new versions. Why? Is this option somewhere else? If not why have you removed this very good feature from the new releases? If I need to delete the content of the site, for example to maintain and delete old files, I need to solve it via FTP SERVER, why so complicated!
