    Unable to view remote LAN folders in different extension formats (ext4, etc). TreeSize can see them well.

    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

    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.

    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.
