gdu

gdu is a cross-platform disk usage analyzer written in Go by developer Daniel Milde, designed to deliver an exceptionally fast graphical overview of storage consumption on Windows systems. The utility belongs to the System Utilities / Disk & File Software category and is currently offered in version 5.34.2, the sixteenth public release since its introduction. By leveraging Go’s concurrency features and a minimalist terminal user interface, gdu quickly scans entire drives or selected directories, sorts folders by size, and highlights the largest space consumers through an interactive tree that can be navigated with arrow keys. Typical use cases include identifying forgotten archives, locating redundant game installations, preparing systems for migration or backup, and assisting IT administrators in routine storage cleanup tasks on workstations and servers. Because the program operates without background services and writes no registry entries, it can be run portably from a USB stick or deployed on production machines with minimal footprint. The single executable supports Unicode paths, respects NTFS junctions, and offers optional export of scan results for further analysis. After more than a dozen iterative updates, gdu has evolved from a simple CLI experiment into a mature analyzer that competes favorably with heavier GUI counterparts while remaining lightweight enough to inspect multi-terabyte volumes within seconds. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
