In fact, we believe WizTree to be the fastest application of this type currently available! Use the information WizTree provides to quickly locate and remove "space hogs" from your hard drive.

How does it work?
WizTree reads the hard drive's Master File Table (MFT) directly from the disk. The MFT is a special hidden file used by the NTFS file system to keep track of all files and folders on a hard drive. It's very fast because scanning for files this way completely bypasses the operating system (Windows).
Why are some of my drives not selectable?
WizTree obtains information by directly scanning the the MFT file, so it can only work with local (directly attached) drives formatted with the NTFS file system. It won't work with network drives, substituted drives or non NTFS formatted drives. We may add support for other drive types in the future if there's enough demand.
