Download WinSCP Portable 5.1.1 Free

WinSCP Portable is the standalone version of WinSCP, a powerful FTP client that has been especially developed for secure file transfers.
WinSCP Portable doesn't require installation and though is quite easy to use, its interface may appear a bit overwhelming at first due to the extra security options.
Besides the standard FTP protocol, WinSCP Portable also supports both SFTP and SCP over SSH-1(Secure Shell) and SSH-2, which make your file transfers secure and avoids third-party interception.
Another handy feature in WinSCP Portable is the possibility to save sessions, so that you can pause file transfers at any point and resume them later on.
WinSCP may not be the easiest FTP client, but it's definitely one of the most secure. If you're concerned about your file transfers, this is what you need.
