Storage Analyzer for Windows — Find What's Filling Your Drive

See exactly what's eating space on your Windows PC with a fast treemap, duplicate finder, and large-file report. Read-only — nothing changes without your click.

Why Windows users need a real storage analyzer

Windows Storage Sense gives you broad categories but no detail. SafeRestore Storage Analyzer scans every folder, builds an interactive treemap, finds duplicates by SHA-256, and surfaces the usual culprits (Hibernation file, Temp folder, OneDrive cached folders, Windows.old). Read-only by default — cleanup is manual or via the FilePilot upgrade.

Common use cases

• C:\ drive nearly full
• OneDrive sync taking unexpected space
• Game and Steam cache cleanup
• Windows.old folder after upgrade

Frequently asked questions

Does it work on Windows 11?

Yes — fully supported on Windows 10 and Windows 11, x64 and ARM64.

Will it touch my system files?

Never automatically. Read-only by design. Suggestions surface system-safe candidates first; you choose what to delete.

What about WSL and Docker?

We detect WSL ext4 vhdx files and Docker overlay disks separately so you can see how much space your dev environments use.

Is my disk content uploaded?

No. Scanning runs entirely on your PC; folder names and sizes never leave your device.
