swapon --show               # see what swap files you have active
sudo swapoff /swapfile      # disable /swapfile
# Create a new 16 GiB swap file in its place (could lock up your computer 
# for a few minutes if using a spinning Hard Disk Drive [HDD], so be patient)
sudo dd if=/dev/zero of=/swapfile count=16 bs=1G
sudo mkswap /swapfile       # turn this new file into swap space
sudo chmod 0600 /swapfile   # only let root read from/write to it, for security
sudo swapon /swapfile       # enable it
swapon --show               # ensure it is now active
