Hey, thanks for this. Was using WinDirStat. This is really fast! Plus I like the minimalistic interface.

Thanks for the recommendation. faster than "space sniffer" as well.

YES! I really wish there were others that scanned the MFT. I don't think Wiztree is as flexible with visualizations.

That's misleading - TreeSize also works by scanning the MFT.

Sadly as a consequence of this, it can only report file size, not disk usage. If you have a lot of folders with NTFS compression enabled, Wiztree becomes almost useless.

I like it too but I've found it to be pretty buggy sometimes, especially if the contents of a folder change or the folder itself is deleted while you're viewing it, you get an endless stream of Delphi exceptions.
