    WinDirStat is free and open source, which means it works on my windows Server without needing to pay for it the way TreeSize does.

    I really like the duplicate finding tool though it has some quirks - its died on me a few times while tryig to save out the CSV and it doesn't seem to properly reload from csv - causing me to have to rescan. It also doesn't seem to save or give an option to save for the duplicates -

    Still it's free, open source and has helped me quickly find where my space has been going to.

    I see they are currently almost ready with a new release, so it's under active development

    WinDirStat locks up when analyzing my Downloads folder. If it locks up that easily, it's not a good alternative.

    WizTree is faster and much more accurate than Treesize as it properly handles hard linked files (doesn't count them more than once) so the total allocated size reported by WizTree will actually match the space used on the drive as reported by Windows.

    Much faster than all others I've tried, even on network shares. The visualization looks very similar to windirstat, almost identical.

    It is very fast, even on remote disks. I use it to manage my Google Drive through Google File Stream.

    Not only does it report folder sizes, but it's also a file manager with tremendous feature, and has toolbars above, bellow, splitting a pain, and to the left right which are fully customize-able with internal commands or external programs & scripts. And it takes screen shots, and so much more. I'm so impressed with it, and I'm very difficult to please.
