Where Is My Storage Going?
Your phone says "Storage almost full" but you can't figure out what's consuming it. Photos look manageable, you don't have many apps installed, and Downloads seems small. Yet 90% of your 128 GB is used. Where did it go?
The answer is almost always a combination of hidden storage consumers that the default file manager doesn't reveal clearly. Here's how to find them with AnExplorer.
The Usual Suspects — Largest Storage Consumers
Based on typical Android phone usage after 1-2 years:
| Location | What's there | Typical size | How to check |
|---|---|---|---|
DCIM/Camera | Photos and videos you've taken | 5-50 GB | AnExplorer → DCIM → sort by size |
Android/obb | Game data files | 5-30 GB | AnExplorer → Android → obb → sort by size |
Android/media/com.whatsapp | WhatsApp photos, videos, voice notes | 5-20 GB | Navigate directly or use WhatsApp Manager |
Android/data | App caches and private data | 3-15 GB | AnExplorer → Android → data (grant SAF access) |
Download | Downloaded files (PDFs, APKs, images) | 2-10 GB | AnExplorer → Download → sort by size |
| App caches (system) | Invisible cached data | 2-10 GB | Settings → Storage → Cached data |
Telegram | Telegram media downloads | 2-10 GB | AnExplorer → Telegram → sort by size |
Movies / Music | Downloaded media | 1-20 GB | AnExplorer → Movies or Music |
Method 1: Sort by Size (Quick Discovery)
The fastest way to find large files:
- Open AnExplorer → Internal Storage
- Tap sort button → Size → Largest first
- The biggest folders appear at the top
- Tap into each large folder → sort by size again
- Drill down until you find the specific large files
What you'll typically find:
- A few 4K videos (1-5 GB each) in DCIM
- Game OBB files (5-25 GB per game) in Android/obb
- WhatsApp videos forwarded in group chats (hundreds of MB each)
- Old downloads you forgot about (APKs, PDFs, ZIP files)
Method 2: Memory Cleaner (Automated Scan)
AnExplorer's Memory Cleaner scans for reclaimable space automatically:
- AnExplorer → ☰ → Memory Cleaner
- Wait for scan (5-15 seconds)
- Results show categories:
- Duplicate files — same file in multiple locations
- App cache — temporary data safe to delete
- Empty folders — leftover from uninstalled apps
- Old APKs — installation files no longer needed
- Large files — biggest individual files on your device
- Select categories → Clean
Typically recovers 2-8 GB without deleting anything important.
Method 3: Check Specific Problem Areas
Camera photos and videos (DCIM)
The #1 storage consumer for most users:
- AnExplorer → DCIM → Camera → sort by size
- 4K videos are the biggest (1-5 GB for a few minutes)
- Burst photos (10-20 shots of the same scene) waste space
- Old screenshots accumulate in DCIM/Screenshots
Action: Delete old videos you've already shared/backed up. Keep only the best burst shots. Clear old screenshots.
Game data (Android/obb)
Games are massive and their data persists even after you stop playing:
- AnExplorer → Android → obb → sort by size
- Each folder is named by package (e.g.,
com.miHoYo.GenshinImpact= Genshin Impact) - Games you haven't played in months still consume 5-25 GB each
Action: Delete OBB folders for games you no longer play. You can re-download from Play Store if you want to play again later.
WhatsApp media
WhatsApp accumulates media from every chat and group:
- AnExplorer → Android/media/com.whatsapp/WhatsApp/Media
- Check Video folder (usually the largest — forwarded videos)
- Check Images folder (memes, screenshots shared in groups)
- Check Audio folder (voice notes)
Action: Delete old videos (especially forwarded ones from groups). Use AnExplorer's WhatsApp Manager (☰ → WhatsApp) for a categorized view.
Downloads folder
Everything you've ever downloaded accumulates here:
- AnExplorer → Download → sort by size
- Old APKs (no longer needed after installation)
- PDFs you read once
- Images saved from browsers
- ZIP/RAR files already extracted
Action: Delete APKs (apps are already installed). Delete old documents you no longer need. Clear extracted archives.
App caches (hidden)
Apps cache data invisibly:
- Settings → Storage → shows total cached data
- Or: AnExplorer → Memory Cleaner identifies cache
- Common large caches: Chrome (1-2 GB), Instagram (1-3 GB), YouTube (500 MB-2 GB), Spotify (1-4 GB)
Action: Clear cache per-app (Settings → Apps → app → Storage → Clear cache) or use Memory Cleaner.
How Much Space Can You Recover?
Typical recovery by user type:
| User type | Expected recovery | Main sources |
|---|---|---|
| Light user | 3-8 GB | Old downloads, app cache, screenshots |
| Average user | 8-20 GB | WhatsApp videos, old photos, game data, cache |
| Heavy user | 20-50 GB | Multiple games, large video library, years of WhatsApp |
| Photographer | 10-40 GB | RAW files, burst photos, old shoots |
| Gamer | 15-50 GB | Unused game OBB data |
Prevention — Keep Storage Under Control
- Monthly cleanup: Run Memory Cleaner once a month
- Delete after install: Remove APK files after installing apps
- WhatsApp auto-download: Disable auto-download for videos in groups (WhatsApp → Settings → Storage → Media auto-download)
- Back up then delete: Move old photos/videos to NAS or cloud, then delete locally
- Uninstall unused games: Don't just stop playing — uninstall to reclaim OBB space
- Clear browser cache: Chrome → Settings → Privacy → Clear browsing data → Cached images
