c$ is not a real share it is part of the network structure for administrative purposes.
You need to actually "share" a drive or folder.
In My Computer, right click either a drive or a folder and click on share ...
it should be obvious from there.
When you open My computer or Explorer after this you should see a "hand" under every folder or drive you have shared.
I would suggest sharing the entire c: drive at first all folders and files within it will then be visible.
The same applies with printers. go into printers and select share... etc.
You need to share folders or drives on both computers. It should be straightforward.
