I think Donald was asking how to use
Mount Network Share which also works well to transfer files wirelessly. To do this you need to share a folder from your PC.
Here I have created the folder TriumphLS on my Desktop and right clicked on it, selected Properties and then enabled Sharing in the Sharing tab.
Then in the Browse Files screen choose Mount Network Share from the File Operations menu when you are in the System Root directory.
Then enter the network path as shown above along with your Windows account name and password.
Press OK and you should now see this folder shared in the Root Directory where it can be used to import and export files.
