You can't share a folder like that between two computers over the internet, they have to be physically connected in a network.
Tell us more about this setup.
I have been trying to set up a network folder on my work PC where I can access it from my home PC. So far I have created the shared folder on my work PC, but now I am stuck as what to do here. I have the IP address and computer name of my work PC, as well as the directory path for the shared folder. However I am not sure what steps to do in order to connect from my home PC.
