Scanning for files this way completely bypasses the operating system (Windows) and provides a huge performance boost. 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. When scanning NTFS formatted hard drives (most modern hard drives use this format), It reads the hard drive's Master File Table (MFT) directly from the disk.
It does this in the FASTEST way possible - you simply won't find any other application of this type that's quicker! Use the information Wiz Tree provides to quickly locate and remove 'space hogs' from your hard drive.
It scans your hard drive and shows you which files and folders are using the most disk space. WizTree is the world's fastest disk space analyzer. WizTree is a hard drive disk space analyzer similar to WinDirStat but is MUCH faster.
