What is WinSCP

WinSCP (Windows Secure Copy) is software that allows you to securely transfer files between a local computer and a remote server. It uses several communication protocols, including:

  • SFTP (SSH File Transfer Protocol)
  • SCP (Secure Copy Protocol)
  • FTP (File Transfer Protocol)
  • FTPS (FTP over SSL/TLS)
  • WebDAV

The program combines strong data protection (thanks to SSH encryption) with an intuitive user interface, similar to Windows Explorer.

WinSCP is mainly used for:

  • Transferring files to and from remote servers
  • Editing files directly on the server using an editor Integrated
  • Synchronize directories between local machine and server
  • Automate transfer operations via scripts or command-line interface
  • Manage remote file permissions

It is especially useful for:

  • Upload website files to hosting servers
  • Make backups from remote servers
  • Administer Linux/Unix servers from a Windows machine

  • Type of protocol to use (e.g., SFTP, FTP, etc.)

This data They should be inserted in the main window when creating a new session. Once saved, the session can be easily reused.

  • On the left: files and folders on your computer
  • On the right: files and folders on the remote server

WinSCP includes a integrated text editor, useful for editing configuration files or scripts directly on the server. It also allows you to synchronize directories, comparing and updating only modified files.

  • Batch scripts to automate recurring tasks

winscp.com /command "open sftp://user@host" "put file.txt /home/user/" "exit"
