title: SFTP file transfer in Windows using script with no external dependency
body: <p>I need to know can we transfer file through SFTP using script.</p>
  <p>I am able to ping server from my system but when I use <code>ftp</code> command it shows <em>&quot;connection lost&quot;</em> and when I use <code>sftp</code> command it shows <em>&quot;command does not exist&quot;</em>.</p>
  <p>No external PuTTY or WinSCP can be used.</p>
  <p>Thanks in advance!</p>
