title: configure username and password for already mapped UNC path in ssis using file system task.
body: <p>I was refering this : <a href="https://stackoverflow.com/questions/4258716/ssis-accessing-a-network-drive-using-a-different-username-and-passoword">SSIS: Accessing a network drive using a different username and passoword</a>  </p>
  
  <p>But, here it seems that unc location is mapped runtime. My case is bit different, my unc location is already mapped and I just need to configure username and password in my configuration file.how can I do this in ssis package.</p>
  
  <p>Note- I need to copy file to unc location.</p>
  
  <p>Thanks.</p>
