Please refer to the following steps to setup SFTP on Windows Server 2016.

1. At first, Download OpenSSH-Win64.zip from https://github.com/PowerShell/Win32-OpenSSH/releases
   
   
2. Create a folder called OpenSSH-Win64 at location C:\Program Files (x86) and extract the downloaded file into it.
   
   
   
   
3. Right-click and open the command prompt with admin credentials and run the below command.
   
   
   
   

   powershell.exe -file ”C:\Program Files (x86)\OpenSSH-Win64\install-sshd.ps1”

   
   
   
   
4. Go to the services.msc >> Find OpenSSH Authentication Agent and OpenSSH SSH Server.
   
   
5. Start both the service and change startup type from Manual to Automatic.
   
   
   
   
6. Go to the path C:\ProgramData\ssh and open the sshd_config file, change the root directory to your path where you want to upload your files using SFTP.
   
   
   
   
7. Create a user to login for FTP. Please refer to Create User > Windows 2016 to create a user.
   
   
8. Provide the Read/Write folder permission to a newly created user and click on the OK button.
   
   
   
   
9. Open your favorite FTP client. Here, we have used a Filezilla FTP client.
   
   
10. Click on Site Manager and enter the below details and click on the connect button.

• Host : Enter Server IP Address.
• Port : 22.
