A Windows tool that scans a drive or folder and shows space usage as a coloured treemap, in which every large file stands out immediately. It offers search by name, size or type, duplicate detection by content and export of the list to CSV. Especially useful for simulation and CAD engineers, whose result folders, meshes and backups quickly take up hundreds of gigabytes. A portable version is also available.
