Remote connection and file transfer

The easiest way to connect from Windows to a remote Linux computer is to fire up cmd.exe and type ssh user@ip where user is the Linux user name and ip is the IP address of the Linux computer. 

For file transfer, you can use sftp user@ip or scp fileName user@remoteIP/remoteFileName.

ssh, sftp and scp come with Windows 10, you don't have to install anything. Just make sure that SSH is enabled on Linux.
