Expand the filesystem

Raspbian is delivered with a limited partition size for the operating system. In order to use the full size of the SD card, it’s required to expand the filesystem. So, log into your Raspberry Pi console as a sudoer and type this:

sudo raspi-config

Choose “Expand Filesystem” (it’ll do it immediately, no confirmation!), then “OK”, in the main menu “Finish” and restart the Pi.
