Storage Doctor doesn't just delete temp files. It explains what is using your disk, why those files exist, and whether they're safe to remove — so you reclaim gigabytes with total confidence. Insight before deletion.
Most cleaners show you a vague "Temporary Files: 12 GB" and hope you press delete. Storage Doctor tells you the whole story first.
See exactly which folders, files and apps are consuming space — and a plain-English description of what each one actually is.
Every recommendation carries a risk level and an explanation, so you never guess whether removing something will break your system.
See precisely how much space each action recovers before you commit. Nothing is ever deleted without your confirmation.
No setup, no accounts, no cloud. Open the app and start understanding your disk immediately.
Scan C:, D:, E: and external drives. Watch folder sizes, file counts and progress update in real time.
Get total, used, free and recoverable space at a glance, plus your biggest categories, folders and files.
Inspect large files, duplicates and app caches — each with a description, risk level and recoverable size.
Delete, move, ignore or open any item. Every deletion is confirmed by you — never automatic.
A complete toolkit for seeing, understanding and safely reclaiming your storage.
Run a full scan of every local and external drive, then read your whole disk at a glance — total size, used, free and recoverable space, with your largest categories, folders and files ranked for you.
Instead of dumping everything into a generic "cache" bucket, Storage Doctor categorizes each opportunity with a description, the exact space you'll recover, a risk level, and a recommended action.
Find true duplicate files by their SHA-256 content hash — not just matching filenames — and see how much space well-known apps like Chrome, Steam, Docker, VS Code and Adobe are quietly using.
Scans C:, D:, E: and external drives, calculating folder sizes, file sizes, file counts and scan duration live.
Total, used, free and recoverable space with your largest categories, folders and files ranked at a glance.
Identify the folders eating the most space and open an expandable, percentage-based breakdown of each.
Locate files over 100 MB to 10 GB thresholds — ISO, ZIP, MP4, PSD, VHD and more — then open, move, delete or ignore.
Recognizes Chrome, Steam, Docker, VS Code, Adobe and more, estimating each app's storage and cache usage.
Categorized suggestions with a description, recoverable size, risk level and recommended action for each.
Finds true duplicates by SHA-256 content hash across images, video, documents, archives and music.
Flags big ZIPs, old installers, ISO images and unused setup files, noting when each was last opened.
Search across folders, applications, files, extensions and recommendations from one box to find anything fast.
Storage Doctor is a brand-new app, so Windows Defender SmartScreen may show an "unknown publisher" warning the first time you install it. This is normal for new software that hasn't yet built up download reputation — it is not a virus alert. We do not promote, bundle, or use any harmful code, and no file contents ever leave your computer.
To install if the warning appears:

No. Storage Doctor never deletes anything automatically. Every cleanup action requires your confirmation, so you stay in full control of what stays and what goes.
No file contents ever leave your computer. Scanning is fully local and no telemetry is enabled by default. Only payment-related requests use the internet, over HTTPS.
Storage Doctor is a brand-new app, so Windows SmartScreen may show an "unknown publisher" warning until it builds up download reputation. This is normal for new software and is not a virus alert — the app is 100% safe and secure, with no harmful or hidden code. To continue, click "More info" and then "Run anyway".
Traditional cleaners show generic categories like "Temp" or "Cache" and delete them. Storage Doctor explains what each item is, why it exists, whether it's safe to remove, and exactly how much space you'll recover — insight before deletion.
It scans all local drives such as C:, D: and E:, as well as connected external drives.
Duplicates are identified by cryptographic SHA-256 hashes of the file contents rather than by filename, achieving over 99% accuracy across images, videos, documents, archives and music.
Almost everything is free — drive scanning, the storage overview, folder analysis, the large file finder, application storage detection, safe cleanup recommendations, the downloads analyzer and search. Pro adds just two power tools: Duplicate File Detection & Removal, and exporting your full process report as a PDF.
Stop guessing what's filling your drive. Download Storage Doctor and understand your storage in under 90 seconds.
