It's been a dog's age since I played with a VPN on Windows. You can set up an VPN following these instructions:

So I did it and then thought: "OK, what now? How do I navigate or see directories?". I had forgotten.
Open an Explorer window (Windows key + e) and in the navigation bar, type in a double backslash followed by the IP address followed by another backslash then C$ to get to the base C drive directory. From there, click to your hearts content to navigate.
Hope this helps.
