Disk Usage Analyzer, also known as Baobab, is a graphical utility for examining disk usage and folder structures. It is developed as part of the GNOME desktop environment.
The application helps users understand how available storage is being consumed. It can scan individual folders, local storage devices and accessible remote locations, displaying the results in a form that makes large directories easy to identify.
Disk Usage Analyzer combines a directory tree with a graphical representation of storage consumption. This makes it possible to examine a directory numerically while also seeing how its files and subdirectories contribute to the total size.
The application is useful when a disk is approaching capacity and the cause is not immediately obvious. It provides a straightforward way to investigate the filesystem without requiring familiarity with command-line disk usage utilities.
Its integration with the GNOME desktop makes it a natural choice for users who prefer applications that follow GNOME’s interface conventions.
This is free and open source software.
