Help me about WinSCP 5.7.2 software and its benefits

Is it translated into several languages? Is there drag and drop option? Can this support SFTP and SCP protocols over SSH-1 and SSH-2? Can I integrate text editor with this? Can I store session information by using this? Is it open source software? Can I integrate Macromedia DW by using WinSCP 5.7.2? Where it is different from File Zila? Is it only windows based software? Has it Explorer and Commander Interfaces? Is it supported for SSH password and how doing it? Thank You
