Safe? Puntuado con 3 de 5 estrellas

I have question.... Is it safer FTP client then Filezilla?

It's as safe as Filezilla, as far as I know! It's better to use SFTP or FTPS. For any FTP client, the FTP protocol itself can be insecure (in the same way HTTP is insecure but HTTPS isn't). Hope that helps!
