Folder Android/obb on your smartphone is a storage of additional data for games and applications. Graphic textures, levels, sound files and other resources that are too large for the main APK are saved here. But over time, this folder grows to several gigabytes, taking up precious space. This is especially true for devices with 32–64 GB of memory, where every megabyte counts.

Many users try to simply delete files from obb manually, but encounter errors: games stop launching, display messages about damaged data, or require re-downloading content. This is because the Android system protects these files from accidental deletion - they are tied to specific applications through unique identifiers. Today we’ll look at how to clear a folder obb without consequences, which files can be deleted and which should not be touched, and what to do if after cleaning the games refuse to work.

Attention: if you use root access or custom firmware, some of the instructions may not work. In this case, we recommend going straight to the section about ADB commands —they give more control over system folders.

What is the OBB folder and why can’t you just clear it

Folder Android/obb (from Opaque Binary Blob) was introduced by Google as standard storage for large additional application files. Unlike the cache, which can be cleared through the settings, the content obb is counted an integral part of the game or app. That's why the system protects it from accidental changes:

✅ What is stored in OBB:

  • 🎮 3D models and textures for games (for example, Genshin Impact or Call of Duty Mobile)
  • 🎵 Sound tracks and voice packages (as in Garena Free Fire)
  • 🗺️ Maps and levels (for example, in Asphalt 9 or PUBG Mobile)
  • 📦 Data for offline work (as in Google Maps or Netflix)

❌ What will happen if you delete OBB files without preparation:

  • 🚫 The game will stop launching with an error "The data files are damaged"
  • 🔄 The application will start downloading the data again (will waste traffic and time)
  • 💥 Other apps may malfunction if they use shared resources

The Android system associates each file in obb with a specific application package through the view name com.game.package.main.obb. If you delete the file, but do not delete the application itself, a conflict will arise: the system will look for data that does not exist. Therefore simple deletion through Explorer is the worst option.

⚠️ Attention: On some devices (for example, Xiaomi with MIUI or Samsung with One UI) the folder obb may be hidden or blocked system. In this case, you will need root access or ADB.

Method 1: Removing OBB through a standard file manager

This is the simplest method, but it only works if you are ready delete the application itselffiles. If you no longer need the game or app, follow the instructions:

1. Open any file manager (for example, Files by Google, Total Commander or built-in Mi File Manager).

2. Go to the path: 

/sdcard/Android/obb/

3. Find the folder with the name application package (for example com.activision.callofduty.shooter for Call of Duty Mobile).

4. Delete the entire folder or individual files with the extension .obb.

⚠️ Important: After this, be sure to delete the application itself via Settings → Applications, otherwise the system will try to recover the data.

Make a backup copy of your saves (if necessary)

Remember the name of the data folder

Make sure the application is not in use

Connect the phone to charge (for long operations)

-->

If you want save the game, but free up space, this method is not suitable. In this case, proceed to the next method - clearing through the app settings.

Method 2: Clearing the cache and application data (without deleting) APK)

Many games allow reload OBB files without completely deleting. This is useful if the data is damaged or takes up too much space. Here's how to do it:

Open Settings → Applications.

2. Find the desired game or app (for example, Genshin Impact).

3. Press Storage → Clear cache i Clear data.

4. Launch the application again - it will offer to download the data again.

🔹 Advantages of the method:

  • 🔄 Does not require root access or ADB
  • 📱 Saves the APK file (no need to download the game again)
  • 🛡️ Minimal risk of errors

⚠️ Disadvantages:

  • ⏳ You will have to wait for the data to be downloaded again (may take several gigabytes)
  • 🎮 Not all games support this mechanism (for example, PUBG Mobile may require a complete reinstallation)
💡

If the game does not offer to download OBB again after clearing the data, try reinstalling it via Google Play - this often solves the problem.

Method 3: Using ADB to remove OBB (without root)

If standard methods do not work (for example, the folder is locked), you can use Android Debug Bridge (ADB). This is a debugging tool that allows you to manage files through your computer. Here are step-by-step guide:

1. Install ADB on your PC:

- Download Platform Tools from Google.

- Unzip the archive to any folder (for example, C:\adb).

2. Enable USB debugging on your phone:

- Go to Settings → About phone → Build number and press 7 times to activate the mode developer.

- Go back to Settings → System → For developers and enable USB debugging.

3. Connect your phone to the PC and run the commands: 

adb devices

(your device should appear)

adb shell

rm -rf /sdcard/Android/obb/com.game.package/*

(replace com.game.package with the real folder name)

🔹 Commands for working with OBB via ADB:

CommandDescription
adb shell ls /sdcard/Android/obbShow a list of folders in OBB
adb shell rm -rf /sdcard/Android/obb/com.*Delete all OBB files (carefully!)
adb pull /sdcard/Android/obb/com.game /backupDownload backup to PC
adb shell df -hCheck free space on phone

⚠️ Warning: Command rm -rf irreversibly deletes files. If you make a mistake with the path, you can erase important data!

What to do if ADB does not see the device?

1. Make sure that USB debugging is enabled.

2. Try a different USB cable (better. original).

3. Install drivers for your device (for example, Samsung USB Driver or Mi PC Suite).

4. Restart your phone and PC.

Method 4: Removing OBB using root access (for advanced)

If you have root access, you can manage the folder obb as a regular directory. This gives maximum freedom, but also maximum risks. Here's how to do it safely:

1 Install a file manager with root support. (for example Root Explorer or FX File Explorer).

2. Grant the application root access when prompted.

3. Go to /sdcard/Android/obb/ and delete unnecessary files.

🔹 What you can do with root:

  • 🗑️ Delete files selectively without affecting the APK
  • 🔄 Move OBB to an SD card (if supported)
  • 📂 Modify files (for example, replace textures)

⚠️ Risks root method:

  • 🛡️ Security breach (some banking applications will refuse to work)
  • 🚨 Possibility of damaging system files
  • 📵 Loss of warranty (on most devices)

On devices with Magisk you can use the module App Systemizerto transfer OBB files to the system partition. This will free up space in the internal memory, but will require experience with custom firmware.

Method 5: Restoring the system if games do not work after removing OBB

If you deleted files from obb, but forgot to delete the application itself, or the game started throwing errors, try these recovery steps:

1. Reinstall the application:

- Uninstall it via Settings → Applications.

- Download again from Google Play or install the APK manually.

- Launch - the game should offer to download the data.

2. Restore OBB from the backup:

- If you have a backup (for example, through Titanium Backup or manually copied files), return the files to /sdcard/Android/obb/.

- Reboot the phone.

3. Reset the application settings:

- Go to Settings → Applications → [game name] → Storage → Reset settings.

- This will return the application to the “as after installation” state.

🔹 If all else fails:

  • 📥 Try downloading OBB files manually from the site APKMirror or APKPure (search by game name + "OBB files").
  • 🔧 Use apps like OBB Installer to automatically install data.
  • 📞 Contact game support - some developers (for example miHoYo for Genshin Impact) can provide a direct download link.
⚠️ Warning: Never download OBB files from dubious sites. They may contain viruses or pirated content, which will lead to an account ban from the game.

How to prevent the OBB folder from growing in the future

To avoid having to clean it regularly obbfollow these tips:

🔹 Preventive measures:

  • 🗑️ Delete unused games immediately after completion.
  • 📊 Regularly check the folder size obb via a file manager.
  • ☁️ Use cloud saves (for example, in Google Play Games), so as not to be afraid to delete data.
  • 📱 Set up automatic cache clearing in Settings → Storage → Memory clearing.

🔹 Alternative solutions:

  • 💾 Transfer games to an SD card (if the device supports Adoptable Storage).
  • 🖥️ Use emulators (for example, BlueStacks or LDPlayer) for games on a PC - there OBB is stored on the hard drive.
  • 📦 Install "light" versions of games (for example, PUBG Mobile Lite or Call of Duty Mobile Lite).

📌 Example of saving space:

GameAPK sizeSize OBBTotal
Genshin Impact~150 MB~15 GB~15.15 GB
Call of Duty Mobile~70 MB~1.8 GB~1.87 GB
Asphalt 9~50 MB~2.3 GB~2.35 GB
PUBG Mobile~60 MB~1.5 GB~1.56 GB

On some devices (for example Samsung Galaxy S23 or Google Pixel 7) the folder obb may automatically cleared when there is insufficient memory. However, this does not work on all firmware.

💡

Before deleting OBB, always check whether you need the application. If the game is important, use clearing data through the settings, rather than directly deleting files.
