From the developer:
SpaceScan is a free, open-source disk space analyzer for Windows 10 and 11. It finds what is filling up a drive. On NTFS it reads the Master File Table directly, so a whole drive, a 10 TB one included, is mapped in seconds.
A folder tree with size bars, percentages and file counts; file types, and the same totals grouped into categories; the largest files, and search by name, size or age; a duplicate finder with the space you would get back.
