Works well on Windows despite not being maintained. It is the most similar app compared to all other opensource alternatives to SpaceSniffer, the visualization is very similar (when the rectangle vis is selected). It freezes when switching to other visualizations but it works fine otherwise. Note that the sizes reported are slightly off by a few percent compared to the ground truth (eg, instead of 62GB, a folder will be reported as being 60GB), it's not a deal breaker but it's something worth noting. The only totally working and accurate alternative I found is WinDirStats, but Space Radar has the big advantage of being cross-platform (which may explain why it is less accurate, it uses less specific hooks to query files and folders sizes). But it seems to be able to differenciate NTFS symlinks from real files so it does not show redundant calculations. Overall, I am very satisfied by this app, I will reuse it.

It does not give accurate directory sizes. I have a "~/Library/Containers/com.docker.docker/" directory that only contained about 360 KB on disk. However, Space Radar reports it as being 59.6 GB.

On Windows the size reported is a little off from real size but not that much. I experienced this very issue with other softwares (those that cannot distinguish symlinks from real files) but not this one.

Free, performant, and lets me see visually where my hard drive space is taken up. Could be faster, but not too bad for a free tool.
