Files with the extension .obb are additional data for Android games, which are often required for the correct operation of applications from Google Play or third-party sources. They contain graphics, levels, sounds and other resources that do not fit in the main .apkfile. But many users are faced with a problem: how to properly unpack and install these files so that the game works without errors?

In this article you will find unique methods for unpacking OBB filesincluding manual installation through a file manager, using specialized applications and solving common errors. We'll figure out why some games require OBB, how to download them, where to put them, and what to do if the file is damaged or not recognized by the system. The instructions are suitable for all versions of Android - from Android 5.0 Lollipop to Android 14.

What is an OBB file and why do you need it?

File OBB (Opaque Binary Blob) is an archive with additional data for Android applications, which is used for:

  • 🎮 Storing large game resources (textures, 3D models, videos).
  • 📦 Reducing the size of the main .apk-file in Google Play (limit - 100 MB for free applications).
  • 🔄 Content updates without reinstalling the game (for example, new levels in Asphalt 9 or PUBG Mobile).

Without an OBB file, many games will either not start or will work with errors. For example, without OBB, textures will disappear, and without OBB, worlds will not load. It is important to understand that OBB is not an executable file - it cannot be “installed” as GTA: San Andreas without OBB the textures will disappear, and in Minecraft - worlds will not load. It's important to understand that OBB is not an executable file - it cannot be "installed" like .apk. Instead, it needs to be place in the correct folder on the device.

The OBB format is supported by all modern versions of Android, but the path to the folder may differ depending on the manufacturer (Samsung, Xiaomi, Huawei) and the OS version. permissions. Android 11+ due to restrictions Scoped Storage Additional permissions may be required.

Where to download OBB files for Android games?

The official source of OBB files is Google Play, but it automatically downloads data only when installing the game through the store. If you downloaded .apk from a third-party site (for example, APKMirror, APKPure), then OBB will have to be searched separately. Here are proven methods:

  • 🔍 Official developer sites (for example, Rockstar Games for GTA or Moonton for Mobile Legends).
  • 📥 Specialized resources:
    • OBBGames —OBB database for popular games.
    • APKCombo —both APK and OBB included are often posted here.
    • Plati Market —platform with verified files (but be careful with pirated content!).
  • 🤖 Telegram channels (for example, @AndroidGamesOBB —but check your files for viruses!).

⚠️ Attention: By downloading OBB from third-party sites, you risk catching a virus or receiving a damaged file. Always check the hash sum (MD5 or SHA-1) and use an antivirus (for example, Dr.Web or Malwarebytes). If the size of the OBB is very different from that indicated on the official website (for example, 500 MB instead of 1.2 GB), this is a reason to be wary.

💡

Before downloading the OBB, check its version - it must match the version of the game. For example, OBB for PUBG Mobile 2.6.0 will not work for PUBG Mobile 2.7.0 and will cause an error when launched.

Where to unzip an OBB file on Android?

The most common mistake is placing OBB in the wrong folder. The system searches for data files in a strictly defined path:

/sdcard/Android/obb/[game_package]/

Where [game_package] is a unique application identifier (for example, com.rockstargames.gtasa for GTA: San Andreas). You can find out the package:

  • 📌 In the name .apkof the file (for example, com.mojang.minecraftpe_1.20.30.apk).
  • 🔎 Via Google Play: open the game page → copy the URL (for example, play.google.com/store/apps/details?id=com.gameloft.android.ANMP.GloftA9HM —here com.gameloft.android.ANMP.GloftA9HM is the package).
  • 📱 Using the application App Inspector (available in Google Play).

If the folder Android/obb is not on your device - create it manually. It is important to respect the case of letters! For example, the folder OBB (capital letters) will not be recognized by the system.

Device Path to OBB Features
Most Android /storage/emulated/0/Android/obb/[package] Standard path for pure Android.
Samsung /sdcard/Android/obb/[package] or /storage/emulated/0/Android/obb/[package] On some models /sdcard —symbolic link.
Xiaomi/Redmi /storage/emulated/0/Android/obb/[package] You may need to disable "MIUI Optimization" in the settings.
Huawei/Honor /storage/emulated/0/Android/obb/[package] Access may be blocked on EMUI 12+ - you need to give permissions manually.

  2. Rename the extension from .obb to .zip (for example, main.1.com.rockstargames.gtasa.obb → main.1.com.rockstargames.gtasa.zip).
  3. Unpack the archive using WinRAR, 7-Zip or Bandizip.

Inside you will find folders with resources:

  • 🖼️ assets — textures, models, sounds.
  • 📄 lib — libraries for different architectures (armeabi-v7a, arm64-v8a).
  • 🎮 data — saving, configuration.

⚠️ Attention: Changing files inside OBB can lead to:

  • 🚫 Ban in online games (for example, in PUBG Mobile or Free Fire).

Typical errors when working with OBB and how to fix them

Even experienced users sometimes encounter problems when installing OBB. Here are the most common errors and their solutions:

Error Cause Solution
"The file is damaged" Incomplete download or broken archive. Download OBB again, check MD5hash.
"Not enough memory" OBB takes up a lot of space (for example Genshin Impact - 15+ GB). Clear memory or use an SD card (if supported).
"The game does not see OBB" Wrong path or folder name. Check the case of letters in [package] and path (/Android/obb/).
"Error loading data" Conflict between OBB and APK versions. Delete the game, download APK and OBB of the same version.

If the game still does not start after installing OBB, check:

  • 📋 Android version: some games (for example, eFootball) require Android 8.0+.
  • 🛠️ Processor architecture: OBB for arm64 will not work on x86 (check in CPU-Z).
  • 🔒 Permissions: on Android 11+ may require permission to access the folder Android/obb.

On devices with MIUI (Xiaomi) or EMUI (Huawei) sometimes it helps to disable "battery optimization" for the game or use developer mode (Settings → About phone → Build number - press 7 times).

Alternative installation methods OBB

If the standard method does not work, try alternative options:

  • 🤖 Application OBB Installer:
    1. Download the application from Google Play.
    2. Select .apk and .obb files.
    3. Click Install —the app will place the files itself.
  • 💻 Via ADB (for advanced users): 
    adb push main.1.com.package.obb /sdcard/Android/obb/com.package/

    Requires enabled USB debugging (Settings → For developers).

  • ☁️ Cloud services (if OBB is too large):
    1. Download OBB to Google Drive or Mega.
    2. Download directly to your phone (to avoid damage when copying from PC).

      3. For devices without an SD card slot (for example, Google Pixel or OnePlus) and a small amount of memory can be used external storage, but:

      • 🔌 The SD card must be formatted as internal memory (starting from Android 6.0).
      • 🚫 Some games (for example, Honor of Kings) do not support installation on SD.
      💡

      If you have root access, you can move the folder /Android/obb to an SD card from using the application FolderMount or Link2SD. This will save space in the internal memory.

      FAQ: Frequently asked questions about unpacking OBB on Android

      Is it possible to unpack OBB directly on the phone without a PC?

      Yes, but for this you will need a file manager with archive support (for example, ZArchiver or RAR). However, you usually do not need to unpack OBB - just place it in a folder /Android/obb/[package]. Unpacking is only required to modify files.

      Why does the game ask to download data even though OBB is already installed?

      This happens if:

      • The OBB version does not match the game version (update both file).
      • The folder with OBB is named incorrectly (check the register and game package).
      • The game uses additional files .main.2.com.package.obb, .main.3.com.package.obb etc. (download all parts).
      How to transfer OBB to another phone?

      Copy the folder /Android/obb/[package] to a new phone in the same location. Make sure that:

      • The same version of the game is installed on both devices.
      • The new phone supports OBB architecture (for example, arm64).
      • Folder Android/obb exists (create it manually if not).
    Is it possible to delete OBB after installing the game?

    No! OBB contains critical data, and deleting it will lead to:

    • Disappearance of textures, levels or characters.
    • Errors at startup (for example, "Failed to load data").
    • The need to download the data again (which can take hours if the size is large).

      • If you need to free up space, it is better to transfer OBB to an SD card (if supported) or delete the game itself.

    How to check if is OBB installed correctly?

    Open the file manager and check:

    1. Folder presence /Android/obb/[package].
    2. The presence of a file inside it main.[number].com.package.obb (for example, main.1.com.rockstargames.gtasa.obb).
    3. File size - it must match the specified on the website (for example, 1.5 GB, not 500 MB).

    If everything is in place, but the game does not work, try rebooting the device.
