"Find the files and folders using the most space on your hard drive - QUICKLY!"
(WizTree is similar to applications like WinDirStat, TreeSize and Folder Size but is MUCH faster)
Works on 32 and 64 bit versions of Windows XP, Vista, Windows 7, 8 and 10
We can't add it because there is no version number to detect by Patch My PC.
