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

    It's Open Source, Free, and does the exact same thing but faster, yes you may not have the features of the PREMIUM version of Tree Size, but we are comparing the free version.

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