Cons
Con Intended for NTFS only
It'll work with any other file system but with the same speed as any generic space analyzer.
Con Slight learning curve
Con If you are not that patient of a person and want something to just work off the bat this won't be for you
It requires you at least install notepad++ or similar,
learn what it means if '#" is displayed on a line in the config file.
Other then that, the dev. explains everything about the setup you could possibly want to know on his site.
Con Ugly looking
Not meant for Windows 10.
