WTF – Where’s The Filespace is an ultra-fast Windows disk space analyzer.

Its high-speed scanning engine reads NTFS metadata directly from the Master File Table (MFT) and uses native Windows NT directory APIs as a fallback, avoiding slower file-by-file access whenever possible. Results are shown in sortable tree, table, pie and bar chart views and can be saved, loaded, exported or copied to the clipboard.
