I tried unzipping a 37MB RAR file, but system says root is full.
I used sudo baobab / to check, and it shows that / takes up 14.1GB. It acknowledges the fact that the free space exists, but it still shows root as full.
I ran sudo du -h in root and it shows 19GB.
I ran sudo df -i and it shows:

/dev/sda5 3244032 321772 2922260 10% /
I ran sudo df -h --total and it shows:

I used xdiskusage in two different ways:
sudo xdiskusage / , which showed 13.11GB, and
sudo xdiskusage and then chose from the graphical interface the disk / is mounted on, which showed 48.6GB, from which 32.94 is (free), 2.49 is (inodes) and the rest is the actual root.
sudo fdisk -l

The system is running on VMBox. It was initially allocated at 25GB but I expanded the partition into 50 using GParted. The problem started before I messed with the partitioning. I have rebooted the system, in case open but not deleted files are there. No large log files are present (only 349MB).
