What HDGraph is
HDGraph is a free Windows tool for examining how storage space is distributed and locating large folders. Scan a drive or folder, and it calculates the size distribution before presenting directories and subdirectories together in a multi-level pie chart. You can zoom into large directories to inspect deeper levels and decide what to do with the space found. HDGraph works with storage visible in Windows Explorer, including hard drives, SSDs, USB keys, network folders, CDs, DVDs, and cloud storage such as Google Drive and OneDrive. Symbolic links are supported. The current site lists Windows 10 and Windows 11 compatibility. HDGraph 1.5.1 is offered as a portable ZIP, with no installer or administrator rights required. Downloads include a 295 KB package and a 2,414 KB package containing documentation. The free HDGraph plan costs nothing.
