Open Source C++ Disk Space Analyzers

WinDirStat (Windows Directory Statistics) is a disk usage statistics viewer and cleanup tool for Windows. On start up, WinDirStat reads the whole directory tree once and then presents it in three useful views. The official download location and collaboration platform for WinDirStat has moved to GitHub: https://github.com/windirstat/windirstat Downloads and source code provided on SourceForge may not always be up to date. They are primarily used for disaster recovery purposes.

Qt-based directory statistics: KDirStat without any KDE -- from the author of the original KDirStat. QDirStat is a graphical application to shows where your disk space has gone and to help you to clean it up. This is a Qt-only port of the old Qt3/KDE3-based KDirStat, now based on the latest Qt 5. It does not need any KDE libs or infrastructure. It runs on every X11-based desktop on Linux, BSD and other Unix-like systems and of course in a Docker container.

KDirStat (for KDE Directory Statistics) is a KDE program that sums up disk usage for direcory trees - very much like the Unix 'du' command. It also provides cleanup facilities to reclaim disk space.
