I've also been using WizTree for quite a while, but recently learned WinDirStat scans the filesystem instead of trusting the NTFS metadata because it can sometimes be incorrect(?) and is a bit tricky due to poor documentation. The WDS developer actually addressed this in AWDS's issues 4[1] and 19[2] a few years ago, and even said he's contemplating supporting the MFT but it seems he hasn't gotten around to it.
