    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
