bonsize

bonsize allows you to quickly analyze and display the size of directories and files in a tree structure, making it easy to identify which files and folders are taking up the most disk space. It comes with both a fast Command-Line Interface (CLI) and an interactive Graphical User Interface (GUI).

The bonsize-gui application provides an interactive, visual way to explore your disk space usage.

interface with a directory tree, folders, files, and their respective sizes visually represented

You can launch the GUI directly from your desktop application launcher or by running the following command in your terminal:
