What is an OBB File?
An OBB file (Opaque Binary Blob) contains expansion data for Android games and applications. Google Play Store limits APK files to 150MB, so large games store additional assets—textures, sounds, videos, and game levels—in separate These files files.
Think of it this way: the APK is the game engine, and the OBB is the game content. Without both, the game won't run properly.
What's Inside an Such files File?
- HD Textures and graphics — High-resolution images, 3D models, character skins
- Audio files — Background music, sound effects, voice acting
- Video cutscenes — Intro movies, cinematics, tutorials
- Game levels — Maps, stages, environments, world data
- Localization data — Multiple language support files
💡 Technical Note: OBB files are actually ZIP archives, but typically encrypted. You can rename .obb to .zip and try to extract—some games leave them unencrypted, allowing you to see game assets inside.

This type Installation on Android 11/12/13/14+
Starting with Android 11, Google restricted access to the Android/these files folder for security reasons. Here's how to work around it:
Method 1: Use a Supported File Manager
Some file managers have special permission to access Android/the format:
- ZArchiver — Can extract directly to obb folder (best option)
- X-plore File Manager — Has "Allow access to Android" option
- Solid Explorer — Supports Android 11+ restrictions
- MT Manager — Full access with root or Shizuku
Method 2: Use ADB (Computer Required)
- Connect phone to computer with USB debugging enabled
- Open command prompt/terminal
- Push This type file directly:
adb push game.obb /sdcard/Android/these files/com.game.name/
Method 3: Use XAPK Installer (Easiest)
The easiest solution is to download games as XAPK files, which bundle APK + OBB together:
- XAPK files auto-install to the correct location
- Apps like APKPure and SAI can install XAPK directly
- No manual file copying required
Method 4: Grant Full Storage Access
- Go to Settings → Apps → [Your File Manager]
- Tap Permissions → Files and media
- Select "Allow management of all files"
- Some file managers also need: Settings → Privacy → Permission manager → Files → [App] → Allow all files
Understanding OBB File Names
These files files follow a specific naming convention:
[type].[version].[package.name]these files
| Part | Meaning | Example |
|---|---|---|
| Type | main or patch | main |
| Version | APK version code (not version name) | 1234 |
| Package Name | App identifier | com.supercell.clashofclans |
Main vs Patch OBB
- main.XXX.packagethese files — Primary game data (always required)
- patch.XXX.package.obb — Additional updates, DLC content (optional)
💡 Version Matching: The version number in the OBB filename must match the installed APK's version code. If APK has versionCode 1234, you need OBB with 1234 in the filename. Mismatched versions = game won't work.
