Every user who has encountered installing heavy games like PUBG, Call of Duty or Genshin Impact knows that one APK installation file is not enough. After installation, the application requires additional data, which often takes up gigabytes of memory. It is these files that are stored in a special directory, which the system hides from the eyes of the average user in order to prevent accidental deletion of critical components.
Search OBB folders becomes a necessity when you want to manually transfer the cache to a memory card, clean up space, or fix the “data files are damaged” error. In modern versions of Google's operating system, the path to this data has changed, which causes confusion among owners of new smartphones. Let's take a look at where to look for these files and how to work with them correctly.
Understanding the structure of the file system Android allows you not only to solve problems with launching games, but also to create backup copies of progress. Many modification enthusiasts are looking for ways to replace standard resources with improved textures or cracks. Without knowing the exact location of system folders, such manipulations are impossible, and attempts to find them “at random” often lead to software malfunctions.
What is the OBB folder and why do you need it?
The abbreviation OBB stands for Opaque Binary Blob. This is a special container for storing large amounts of data that is not practical to pack inside the main application installation file. Google introduced this format to reduce the size of APK files in the Play Market and speed up the initial download process.
Inside this directory are usually high-resolution textures, audio tracks, videos and level scripts. If you delete the contents of this folder, the game will simply stop launching or require you to re-download gigabytes of data every time you log in. This is why manually deleting files from here without a prior backup can lead to loss of progress. in games that do not use cloud saves.
System logic Android suggests that these files should be accessible only to the application to which they belong. However, for users with root access or when connected to the computer in debug mode, this data becomes visible. This allows you to transfer games between devices without re-downloading traffic.
⚠️ Attention: Do not try to manually change the folder structure inside OBB. Renaming even one subfolder with a digital identifier (for example, com.game.name) will cause the application to no longer see its data.
Developers use this mechanism to separate the free version of the game and paid content. Often the base APK weighs 50 MB, and the OBB folder contains 2 GB of graphics. This is especially true for devices with limited internal storage, where every megabyte of free space is important.
Standard path to files on different versions of Android
The location of data files directly depends on the version of the operating system installed on your device. Before the release Android 11 the structure of the file system was more open and understandable for the average user. The path was the same for all applications and could easily be found through any file manager.
The classic path, relevant for devices based on Android 10 and below, is as follows:
/storage/emulated/0/Android/obb/Or if you are using File Explorer, just go to the root of the internal memory, open the folder Android, and then obb. This is where all loaded caches are located. However, with the release Android 11, 12, 13 and 14 Google's security policy (Scoped Storage) has become significantly stricter.
Now standard file managers often show an empty folder or even hide the contents of the directory Android, claiming that access limited. This was done to protect user data from malware, but made life more difficult for those who are used to managing files manually.
On newer OS versions the physical path remains the same, but programmatic access to it is blocked for standard applications. To see files, you now need to use special methods to bypass restrictions or third-party explorers with special access rights.
How to access OBB on Android 11-14
Owners of modern smartphones are faced with a situation where, when they try to enter a folder Android/obb they see a message about lack of access or a blank screen. The standard Files file manager from Google or built-in solutions from Samsung, Xiaomi i Realmefy security rules and do not show the content.
There are several proven methods to solve this problem. The most reliable way is to use a specialized file manager that can request extended access rights through the system API. One of these popular tools is an application Files (not to be confused with the system one from Google) or Total Commander with plugins.
The action algorithm usually looks like this:
- 📂 Download and install an advanced file manager, for example ZArchiver or Material Files.
- 🔐 When accessing the folder for the first time
Androidthe system will prompt you to allow access. - ✅ Click “Allow” and confirm the action in the pop-up system window.
- 👁️ Now the contents of the folder
obbwill become visible and available for editing.
Another method is to connect your smartphone to your computer via a USB cable. In file transfer mode (MTP), computers running Windows or macOS often ignore Scoped Storage restrictions and show the full folder structure. You can copy files directly to your PC's hard drive.
⚠️ Attention: MIUI, OneUI and ColorOS shell interfaces may differ. If the standard method does not work, try temporarily disabling “Privacy Protection” in the developer settings, but do not forget to enable it back after completing the operations.
Some users resort to installing older versions of file managers that have not yet received updates that block access to system folders. However, this is a temporary solution that may create holes in the system's security.
Use the ZArchiver application to work with OBB archives and folders. It automatically requests the necessary permissions and correctly displays hidden files on new versions of Android.
Naming structure and contents of folders
Inside the directory obb you will see many folders with strange names. This is not a random set of characters, but unique package identifiers (Package Name). Each folder corresponds to a specific application or game installed on your device.
For example, a folder named com.rockstargames.gtasa refers to the game Grand Theft Auto: San Andreas, and com.tencent.ig is PUBG Mobile. Knowing the exact name of the package, you can easily find the game you need among dozens of others.
The structure inside the game folder is usually as follows:
- 📦 main.version.package.obb — the main data file containing graphics and sounds.
- 📦 patch.version.package.obb —an update file that can supplement or replace part of the data from the main file.
- 📦 data —sometimes there is a separate folder with additional settings or a cache.
The question often arises: is it possible to move these files to SD card? On modern versions of Android, directly moving the OBB folder to an external memory card often does not work, since the security system requires that the executable data be in the internal storage. Attempting to transfer may cause the game to stop launching.
However, if your smartphone supports the Adaptive Storage feature or you are using root access, you can create a symbolic link that will redirect the system to an external drive. This is a complex process that requires caution.
What to do if a folder has a strange name?
If you see folders with names like “123456” or a bunch of random letters, this could be a cache of specific Google services or system applications. Do not remove them unless you are sure of their purpose. It’s better to use the search by the contents of the folder to find the required file by extension.obb>
Solving problems with OBB files
The most common problem is that the game requires you to download the data again, although the files seem to be in the folder. This happens if the integrity of the archive is compromised or the file is in the wrong directory. Make sure that the folder with the package name is located in the root Android/obband not nested in another folder.
Another error is “Not enough space,” although there is free memory. The file system may be fragmented, or the OBB file is larger than 4 GB, which requires a file system exFAT or NTFSrather than the standard FAT32 that is often used on older memory cards.
List of errors and solutions:
- ❌ The file is damaged: Download OBB again from a trusted source, checking the checksum (CRC32).
- ❌ Wrong path: Check for unnecessary subfolders. The path must be direct:
/Android/obb/com.game.name/... - ❌ No access rights: Give the explorer application permission to work with files in the system settings.
If the game crashes immediately after loading the logo, try clearing the cache of the application itself (without deleting the data), and then copy the OBB files again. Sometimes renaming the file helps, if its name contains Russian letters or special characters - leave only the Latin alphabet.
⚠️ Attention: Never unpack .obb files with archivers unless the instructions for the game or mod explicitly require this. The system expects to see exactly the packed binary file.
Comparison of cache management methods
For clarity, let's compare different methods of working with OBB files. The choice of method depends on your goals: just play, modify the game or free up space.
| Method | Difficulty | Security | Efficiency |
|---|---|---|---|
| Automatic loading | Low | High | Medium (takes up space) |
| Manual copying (PC) | Medium | High | High (fast transfer) |
| Using ZArchiver | Low | High | High (convenient on the phone) |
| Root access and transfer | High | Risk of loss of warranty | Maximum (flexibility) |
As can be seen from the table, for most users the best option is to use modern file managers on the device itself. This does not require connecting to a PC and preserves the warranty for the device.
☑️ Check before copying OBB
Transferring data between devices
When buying a new smartphone, you want to transfer progress in games without re-downloading gigabytes. If the game supports login through an account (Google Play Games, Facebook), then just log in. But if the saves are local, you will have to transfer the OBB folder manually.
To do this, connect both devices to the computer. Copy the desired folder from Android/obb from the old phone and paste it into a similar directory on the new one. It is important that the version of the game on the new device matches the version for which the OBB file is intended. If the versions do not match, the game may require resuming or display an error.
Using data cloning applications such as Clone Phone from OPPO/Realme/OnePlus or Smart Switch from Samsungwill often automate this process. They themselves find the OBB folders and move them to the right place, respecting all access rights.
Frequently asked questions (FAQ)
Is it possible to delete the OBB folder to free up space?
Yes, you can, but only if you are ready to delete the corresponding game or download its data again. Deleting OBB files will not damage the system, but the game they belong to will stop working until the data is downloaded again.
Why is the Android/obb folder empty even though the games are installed?
You are most likely using Android 11 or later, and your file manager does not have special permissions. Try using the ZArchiver app or connect your phone to your computer to see the real content.
Where is OBB stored if the game is installed on an SD card?
Even if the application is moved to a memory card, the OBB folder in modern versions of Android most often remains in the internal storage (/storage/emulated/0/Android/obb) for performance reasons and security. Moving it to the SD card manually usually does not work.
How to find out which package corresponds to which game?
The folder name usually matches the address of the game page on Google Play. For example, for WhatsApp it is com.whatsapp. You can use package identifier applications available in the Play Market, which will show the name of the application by the name of its package.
