I just got OSCM running on a RaspberryPi 3B+ outfitted with a USB hard drive. I would like to network it with my old Windows XP desktop PC. (I'm already able to SSH it with Putty over WiFi.) I know very little about networking. I would like to be able to read and write files on the Pi's USB drive from my XP PC. How do I set this up? Does it require the addition of a "Server"?
