| - | As of version 4.0, WinSCP supports three transfer protocols, SFTP, FTP and SCP. Currently, many servers support all three protocols. All have its advantages and disadvantages, while FTP have one big disadvantage, being insecure. This document contains a comparison to help you to decide which is most appropriate for your needs. The comparison describes features that are characteristic to the specific protocol as-is, and features that are caused by the implementation of the protocol in WinSCP. | + | As of version 4.0, WinSCP supports three transfer protocols, SFTP, FTP and SCP. Currently, many servers support all three protocols. All have its advantages and disadvantages, while FTP have one big disadvantage, being insecure. This document contains a comparison to help you to decide which is most appropriate for your needs.
