Pro Handles "hard linked" files correctly - doesn't count them more than once
WizTree is faster and much more accurate than all the others 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.
Con Intended for NTFS only
It'll work with any other file system but with the same speed as any generic space analyzer.
