Find out what's eating your drive, then dig it out.

A fast disk analyzer. It scans a drive or folder across all CPU cores, then lets you explore it as a tree, a treemap or a sunburst chart. Drilling in, finding the biggest files and deleting things is instant, with no rescans.

Fast parallel scansA full system drive with over a million files typically takes seconds.
Three ways to see itA sortable tree, a treemap coloured by file type, and a sunburst chart.
Accurate sizesReal size on disk. Symlinks and junctions are skipped, so nothing is counted twice.
Top 100 largest filesFrom every level of the scan, not just the biggest top folders.
Find the clutterFolders with the most files, which surfaces caches, logs and temp folders.
Safe deletesItems go to the Recycle Bin by default, and totals update instantly.
