WizTree is a hard drive disk space analyser similar to WinDirStat but is MUCH faster. Find the files and folders using the most space on your hard drive - QUICKLY! WizTree reads the master file table (MFT) directly from NTFS formatted hard drives (similar to the way Everything Search Engine works). Visual Treemap allows you to spot large files and large collections of smaller files at a glance. Finds the largest files on your hard drive. Every single file on your hard drive can be sorted in order of size. Sort the content of your entire hard drive by folder size and optionally delete files and folders.
