WizTree

Top Pro

Exceptionally fast for NTFS drives

Because it reads the master file table (MFT) directly from NTFS file system. See More

Top Con

Intended for NTFS only

It'll work with any other file system but with the same speed as any generic space analyzer. See More

Maxim Kamalov's Experience

Top Pro

Multiple view such as tree view, tree map, extension view, file view

Unlike other similar apps, which usually only offer single view, this app offers multiple views. See More

HappyPapatuanuku's Experience

Free and Fast See More

Top Pro

Handles "hard linked" files correctly - doesn't count them more than once

WizTree is faster and much more accurate than all the others as it properly handles hard linked files (doesn't count them more than once) so the total allocated size reported by WizTree will actually match the space used on the drive as reported by Windows. See More

Directory Report

Top Pro

Offers good options for quickly dealing with duplicates

Once duplicates are found you can choose to select certain files based on criteria like when was it created, when was it last modified, size, folders they're in or if the folders they're in contain a particular string. See More

Top Pro

Reasonable rules for finding both duplicate files and folders

The program can find duplicate files based on any combination of size, name, CRC. It can also compare files byte by byte. Also, it can compare folders (with or without subfolders) based on any combination of size, name, CRC as well as file count. See More

CuriousNinhursag's Experience

It is fast and can produce many reports See More

Top Pro

Gives a clear overview of found duplicates

It shows duplicate items grouped with every second group highlighted. See More

dust

Top Pro

Supports NTFS directory junctions

NTFS filesystems use several types of reparse points, one being the directory junction which is akin to a directory symlink on ext2/3/4. dust is able to traverse these successfully and add their contents to the reported sizes unless most other Windows command line tools of this nature. See More
