On Windows, you should switch to WizTree. Rather than recursively calling directory listing functions, it directly reads and parses the file tables itself. This makes it orders of magnitude faster. I have a 2 TB hard drive full of a million files, and WizTree reads and parses it all in under a minute, whereas I can expect WinDirStat to take half an hour. On an SSD, WizTree only takes a couple seconds.
