• Protocol Comparison

As of version 4.0, WinSCP supports three transfer protocols, SFTP, FTP and SCP. Currently, many servers support all three protocols. Each has its advantages and disadvantages, while FTP has 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 both features that are characteristic to the specific protocol as-is, and features that are caused by the implementation of the protocol in WinSCP.

The default mode of operation is to use SFTP and fall back to SCP. Select your preferred protocol on Login dialog.
