I've got a Mac and a Windows PC only home network (i.e. plugged into my broadband router with an Ethernet cable). I want to be able to move files easily between the two machines. As they are already connected to the same network, how can I connect my Mac to the PC so I can browse the C: and D: drives? The PC is running Windows 10. I'm looking for the most secure solution as I'm reluctant to reduce the level of security on either machine.
