You need to do a couple of things, first use the same network workgroup name on each (open system control panel, advanced system settings, computer name tab). In the network control panel click on the top active network and make it a home network instead of public, setting the options as you wish. Then go to the Homegroup control panel and view the password on your computer, then on her computer select leave the homegroup, then join the homegroup -- using your password so that you are both in the same homegroup.
You can set your particular file sharing choices with a right click on a drive or file then make the necessary changes in both the sharing and security tabs.
