How to File transfer

WinSCP Tutorial

Learn How to Use WinSCP

WinSCP (Windows Secure Copy) is an open source SecureFTP client for Windows. It allows secure file transfers between the client's local computer and the remote server. In order to establish a secure connection through WinSCP the SSH support should be enabled. Otherwise, the WinSCP software can be used as a regular FTP client.

The WinSCP software uses cryptographical methods, integrated in SSH to protect your login details and private information. It prevents different types of attacks like password sniffing and malicious monitoring of the sessions between your local computer and the remote server.

The software can be downloaded from the following URL .

It requires Windows OS. The installation of WinSCP is quite simple. Basically you need to click on the Next button several times leaving the default options.

In order to customize it to your likings you can choose between the Norton-Commander interface and the Windows Explorer-like interface.

 

 

The main difference is that the first interface provides 2 panels (one with the local computer directory structure and the other with the remote) while the second shows only the remote. If you are used to work with applications like Norton Commander, Total Commander or Midnight Commander, pick the first option. If you prefer Windows Explored, go with the second.

The interfaces settings can be changed after the end of the installation too.  

Once you are ready with the installation, you can establish a secure connection from your local computer to the remote server.

Open the WinSCP client.

Navigate to the Session section. 

Enter the Host name(192.168.220.100), the Port number(22) and the User Name and the Password Pick the preferred protocol (SCP (Secure Copy)).

 

 

Once the session is opened, you can perform all the standard FTP actions. The difference is that the connection is secured.

 

 

You can keep your connection details by storing them in the Stored Sessions subsection.
