Set Up a Local File Sharing Server on Raspberry Pi 4 B
The latest Raspberry Pi 4B comes with a Gigabit ethernet port, up to 4GB RAM and 2 USB3 port. Because of its low power supply, Raspberry Pi 4 surely has the capability of working as an affordable file server to back up and share files from anywhere on your local network. In other words, all your local devices not only can backup your important files to the Raspberry Pi, but also plays movies stored in the Raspberry Pi. You can even plug external drives to it to enlarge the disk space. In this tutorial, we will use Samba to set up a file server on your Raspberry Pi 4.
