    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.
