Oxide interactive treemap inspecting an elevated C: volume
Engineered to inspect, not decorate.
Oxide is focused on one job: giving you immediate, precise clarity on disk consumption with zero noise.
Direct NTFS MFT Scanning
When run with administrator privileges, Oxide bypasses slow Win32 directory traversals and reads the NTFS Master File Table directly. It indexes millions of records in seconds. On non-NTFS volumes or standard user privileges, it safely falls back to standard filesystem walking.
Drill-Down Treemap
Explore your disk hierarchy through a responsive, color-calibrated treemap canvas. Zoom into deep nested folders, inspect directory sizes at a glance, and navigate back up through instant breadcrumbs.
Largest-Files Inspector
Identify immediate space reclamation targets. A dedicated largest files list aggregates the biggest items in any chosen branch or across the entire drive volume, sorted by true disk allocation.
Reveal in File Explorer
Seamlessly transition from inspection to action. Right-click or trigger the reveal command to open native Windows File Explorer with the exact target file or folder highlighted.
Safe read-only inspection guarantee: Oxide is strictly read-only. It performs safe scanning with no deletion, no automatic cleanup, no file modification, and no duplicate removal. Your files remain completely untouched.
