Secure File transfer between SAP and Windows system.

Dear Team,

We have a Windows 7 Enterprise Edition running on one of our desktops.(Lets say - System A)
We also have a SAP system(Let says System - B) in our landscape which is planning to send files to System A through a secure connection. (FTPs/SFTP)

Can this be achieved through installing WinSCP on System A. If yes, can you please guide me with the steps.

Does System A needs to WinSCP Client or WinSCP server.

Thanks in advance for the reply

You need an SFTP or FTP server on the System A to allow the System B to upload files there.
WinSCP is a client. There's no WinSCP server.
