Finally know exactly what's consuming your Android storage.

Adirstat is a powerful disk space analyzer that works just like WizTree on Windows or Disk Inventory X on Mac. It scans your entire device storage and shows you exactly which files and folders are taking up space — with beautiful visual treemaps and detailed lists.

Key Features:

Interactive Treemap Visualization — See your storage as a visual map where larger files appear as bigger blocks. Color-coded by file type for instant understanding.

All Partitions Supported — Scans internal storage, SD cards, and USB OTG drives. No storage volume left unexplored.

Large Files List — Instantly see your biggest files sorted by size. Find and remove those multi-gigabyte videos and old APKs.

Duplicate Detection — Find duplicate files wasting space. Uses intelligent name+size matching with optional MD5 verification.

File Type Breakdown — See exactly how much space images, videos, audio, documents, and other file types consume.

Per-App Storage Stats — View how much storage each installed app uses (APK, data, and cache). Great for identifying space-hungry apps.

Powerful Search — Find specific files with wildcard patterns (like *.mp4) or regular expressions. Filter by size and date.

Fully Offline — No internet connection required. No account needed. No data ever leaves your device.

Export to CSV — Export your scan results for further analysis or to share with others.

Scan History — Track how your storage changes over time. Compare scans to see what's grown.

How It Works:
Adirstat performs a recursive scan of your storage, calculating the size of every file and folder. It then presents this data as an interactive treemap — a visualization method where each file or folder is represented as a rectangle sized proportionally to its storage consumption. Tap any block to drill down into folders, see details, or delete files.

Why We Need Full Storage Access:
To show you exactly what's using your storage, Adirstat needs permission to access all files on your device (MANAGE_EXTERNAL_STORAGE). This is similar to how file manager apps work. We never use this permission to upload or share your data — it's only used to analyze and display storage information. Your data stays on your device, always.

Privacy First:

No network permissions — zero data can leave your device

No account required

No ads, ever

No tracking or analytics

Open source — verifiable by anyone
