Install filelight by entering the following commands in the terminal:
sudo apt update sudo apt install filelight
Description:
show where your diskspace is being used
Filelight allows you to understand your disk usage by graphically representing your filesystem as a set of concentric, segmented rings. . It is like a pie-chart, but the segments nest, allowing you to see both which directories take up all your space, and which directories and files inside those directories are the real culprits.
