TreeSize analyzes disk space to locate large files and folders for cleanup.
QDirStat
QDirStat provides directory statistics through a Qt-based disk usage application.
About QDirStat
QDirStat is a graphical disk usage application that shows where disk space has gone and helps users clean it up. It shows the total size of directories and their files in a tree view and in a colored treemap, where larger files appear as larger rectangles. Selecting a file in the treemap shows its location in the tree, and the file can be moved to the trash from the application.
It is a Qt6-based port of the older KDirStat and does not require any KDE libraries or infrastructure. The project lists Linux, BSD, other Unix-like systems, and macOS as target platforms. The homepage states that it runs on X11-based desktops and in a Docker container. It is free and open source software licensed under GPL v2.
