PrivaZer vs QDirStat

QDirStat is free graphical software for examining disk usage and cleaning selected files. It displays directory and file sizes in a tree and colored treemap, with views for file types, size histograms, file ages, and free, used, and reserved space on mounted filesystems. Users can select multiple items and run configurable cleanup actions, including moving items to the trash or deleting them. On Linux systems using dpkg, rpm, or pacman, the Packages view lists installed packages and their files; an Unpackaged Files view highlights system files outside those packages. QDirStat targets Linux, BSD, and Unix-like systems on X11 desktops. Third parties provide macOS binaries and Homebrew distribution. There is no native Windows version, although Docker is suggested for non-Linux systems. A Perl script collects headless-server directory data into a cache for desktop viewing; cleanup then occurs on the desktop. Cache files may reveal directory contents and should be protected. QDirStat is GPL V2 software.
