WinSCP

WinSCP is a Windows-based free and open-source graphical file transfer client designed for secure file transfers between a local Windows machine and a remote server. It supports the SFTP, SCP, and FTP protocols, enabling secure or standard transfers as required. It emphasizes SSH-based transfers and host key verification to safeguard connections.

The application provides two main user interfaces: an Explorer-like layout and a dual-pane Commander interface, both aimed at efficient file management. Features include drag-and-drop transfers, directory synchronization, queued transfers, and options to synchronize local and remote directories. It also offers integrated text editing for remote files and a range of transfer settings to tailor workflows.

WinSCP supports automation and scripting through a built-in scripting language and a .NET assembly, allowing batch transfers, conditional logic, and remote file edits. A command-line utility, winscp.com, enables script execution from the Windows command line or batch files, enabling repeatable operations and complex workflows.

For authentication and security, WinSCP integrates with PuTTY for SSH key management and can use Pageant for agent-based authentication. It supports public key and password authentication, along with host key verification. Session data is managed within the Windows profile, and the program includes session logging and robust error handling to aid administration.

The software is developed by Martin Prikryl and has been in active development since the early 2000s. It is distributed under the GNU General Public License and is available as both an installer and a portable package for users who need mobility or a minimal footprint.
