When FTP Requires FTP over TLS is it FTPS?

After reading through this tutorial I still have a persistent question. In the beggining of the article the writer says: > Warning: FTP is inherently insecure! Consider using SFTP instead of FTP. I am assuming that he might mean FTPS (as I think that is what his article explains but I am not sure). However, at the bottom of the article, which is all about how to use vsftpd over SSL/TLS he shows an image that looks like this: Where you can quite clearly see that the Enctryption is to "Require expliticity FTP over TLS". So, is this any different than using FTPS and if it is, what is the difference?
