WizTree is a very fast disk space analyzer and search tool, scanning a single folder or your entire hard drive quickly and showing those files and folders using the most disk space. The program uses the NTFS Master File Table (MFT) feature in Windows to rapidly view files.
Note that this high-speed mode is limited to local, NTFS-formatted drives. The program must do a (much slower) scan of FAT-formatted or network drives for analysis.
