    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.

    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.

    With DaisyDisk you can free up disk space by quickly finding and deleting big, useless files. The program scans any mounted disk and displays it on the sunburst map, where segments mean files and folders, proportionally to their sizes. The map is easy to read and navigate.
