To access any directory (in Linux, they're called directories, not folders) from a Windows PC you will have to do one of two things:
1. Configure samba on your linux box.
2. Install Unix Services for Windows on your PC.
By far, the easiest way is to set up samba. If you're into pain and fustration, install Unix Service for Windows.
for all the gory details (just kidding, it's really easy).
