Modern mobile games take up gigabytes of free space, and over time, users wonder where exactly these files are stored. Understanding the file system structure is necessary to free up memory or back up saves before flashing the device. Unlike regular applications, heavy games they often separate the installation APK and additional content, creating confusion among smartphone owners.
In older versions of the operating system, finding this data was trivial, but with the release Android 11 and newer, the file access policy has become more stringent. Now system folders are protected from direct viewing by third-party file managers without special permissions. This is done for the sake of security, but it complicates life for those who are used to manually managing files.
In this article we will analyze in detail the current paths to the location of the game cache, methods for transferring it to external drives, and methods for safe cleaning. You will learn the difference between folders OBB and Data, and why deleting the wrong files can lead to loss of progress in your favorite game.
Structure of game data storage
The Android file system clearly distinguishes between the executable files of the application and its resources. When you download a game from the store, a small APK file is first installed, and then gigabytes of graphics, sounds and models are downloaded. These resources are stored in special directories, access to which requires an understanding of the logic of the system.
The main storage is located in the internal memory of the device. Even if you have a memory card installed, by default modern games tend to write data to the internal drive to ensure high read speeds. This is critical for performance optimization and the absence of stuttering in dynamic scenes.
⚠️ Attention: Directly editing files inside game folders can lead to data corruption and the application refusing to launch. Always make a backup copy before any manipulation!
System partitions are protected by superuser rights. To access hidden directories, the average user often requires special tools or obtaining root access. However, the base cache folders are accessible through standard file managers if you know the exact path.
Before deleting any files, check their modification date. Files created a long time ago may be remnants of deleted games that can be safely erased.
Main directories: OBB and Data
Most users are looking for the answer to the question of where to find the cache, coming across two treasured folders in the root of the internal memory. This is where the main resources of most popular titles are located. The difference between them is fundamental and determines the strategy for working with files.
Folder Android/obb contains archives with resources that are not encrypted and often have the extension .obb. This is the “skeleton” of the game: textures, music, video screensavers. These files can be transferred between devices, and the game will often recognize them when installing the APK again.
The second key directory is Android/data. This is where more sensitive data is stored, including level caches, temporary files, and, most importantly, saving progress (although many modern games sync this with the cloud). Deleting the contents of this folder for a specific game is equivalent to resetting it to the “just installed” state.
Why might folders be empty?
If you go to the Android/data folder and see it empty on Android 11+, this is not an error. The system has hidden content for third-party applications. Use the built-in file manager or provide special rights in the settings.
It is worth noting that some developers neglect standards and create their own folders in the root of the internal memory. The names of such directories usually coincide with the name of the developer or the name of the game, for example Gameloft or Asphalt. Checking the memory root should always be the first step when searching.
Accessing files on Android 11, 12, 13 and later
Starting with the eleventh version of the OS, Google has introduced a mechanism Scoped Storage (limited storage). This means that standard file managers can no longer see the contents of a folder Android without explicit user permission. This raises a lot of questions for those who try to find the cache in the usual way.
To bypass this restriction without root access, you can use the built-in Files application from Google or the system manager of your smartphone. When you try to open a folder obb or data the system will ask you to confirm access. After clicking the "Allow" button, you will have full control over the directory.
- 📂 Open the standard "Files" or "File Manager" application.
- 📂 Go to the "Internal memory" section and find the folder
Android. - 📂 Try opening subfolder
obb. If an access request appears, confirm it. - 📂 If there is no access, download a specialized manager, for example Total Commander or Solid Explorer.
An alternative option is to connect your smartphone to your computer via a USB cable. In file transfer mode (MTP), Scoped Storage restrictions often do not apply, and you can manage files through Windows or macOS Explorer as with a regular flash drive.
☑️ Checking access to folders
Transfer cache to SD memory card
Owners of devices with a small amount of internal memory often want transfer heavy games to microSD card. However, starting from Android 6.0, support for native transfer of applications to the card was significantly reduced by the system developers. Now this depends on the specific implementation of the shell by the manufacturer.
If your smartphone supports the “Move to SD card” function in the application settings, use it. Go to Settings → Applications, select the desired game and find the corresponding button. The system itself will move some of the data, but the cache may remain inside.
Manual transfer is possible, but requires care. You can copy the game folder from Android/obb in the internal storage to a similar folder on the memory card. However, the game may not see the files if it is hard-coded to look for them only in the internal partition.
| Transfer method | Difficulty | Reliability | Requirements |
|---|---|---|---|
| Application settings | Low | High | Manufacturer support |
| Manual copying | Average | Average | File manager |
| Format as internal | High | High | Data loss on SD |
| root access + Link2SD | High | High | Getting Root |
⚠️ Attention: Formatting the memory card as internal storage will encrypt it. You will not be able to read this card on other devices or a computer without formatting and losing all data.
The most radical but effective method is to use utilities like Link2SD if you have root access. This allows you to create symbolic links, tricking the system into thinking that files are inside, although they are physically on the card.
Clearing the cache and freeing up space
Over time, the game cache can grow to incredible sizes, taking up space with temporary files that are no longer needed. Wiping is a safe way to get back your free gigabytes if you are sure that your progress is saved in the cloud.
The easiest way is to use system settings. Go to Settings → Applications, select the game and click "Storage". There you will see two buttons: “Clear cache” and “Clear data”. The first deletes temporary files, the second resets the game completely.
For mass cleaning, it is convenient to use the built-in optimization tools that are available in the shells MIUI, OneUI or ColorOS. They automatically find junk files and offer to delete them. However, they do not always see the specific cache of heavy games.
If you decide to delete files manually through File Explorer, make sure the game is closed. Deleting files while the application is running may cause the process to freeze and require a forced reboot of the device.
Search for hidden and deleted data
Sometimes users delete a game, but its “tails” remain in memory. These could be logs, unused configs, or downloaded resource packs. Finding them is more difficult, since they are not always located in standard folders obb or data.
Use the file search function in the manager. Enter the name of the game or developer in the search bar. The system will scan all available directories, including hidden ones. Pay attention to files with the extension .log or folders with the name tmp.
For in-depth analysis, you can connect your smartphone to your PC and run a search using a mask. This will allow you to find files that the mobile interface may have missed. Often, the remains of games are hidden in a folder Download or in the root of memory under random names.
⚠️ Attention: Settings interfaces and menu item names may differ depending on the version of Android and the model of your smartphone. If you do not find the item you need, use the search inside the settings menu.
Regularly checking the Android/obb folder for folders from already deleted games can free up from 5 to 20 GB of space on your device.
Access problems and their solution
A common problem is the “Access denied” message when trying to copy or delete a file. This is due to security permissions. In some cases, rebooting the smartphone into safe mode, where third-party defenders are not active, helps.
If all else fails, you can use USB debugging. Activate developer mode, enable USB Debugging and use ADB commands to manage files from your computer. This gives a level of access close to the system one.
adb shell pm grant com.android.documentsui android.permission.MANAGE_DOCUMENTSThis command (requires ADB on the PC) can expand the rights of the standard file manager, allowing it to see protected directories. Use this method with caution, only if you understand the console commands.
Is it possible to delete the OBB folder completely?
Deleting the entire folder OBB is not recommended. Inside there may be data from games you are still playing. Delete only those subfolders that correspond to the name of the deleted games (usually this is the reverse domain, for example, com.rockstargames.gtasa).
Why is the game downloaded again after clearing the cache?
If you cleared the folder Data or deleted the main resource files from OBB, the game there is nowhere to get the content. When launched, it will detect the absence of files and initiate a re-download via the Internet.
Where are game saves stored without an account?
Local saves are most often located in a folder Android/data/[game_folder]/files or in hidden system directories Without Root access, it can be difficult to copy them. When you reset your phone, they will be lost.
Is it safe to use apps to clear the cache?
Most popular cleaners are safe, but some can be too aggressive and delete necessary cache files, which will slow down launching games for the first time after cleaning. It is better to use the built-in system tools.
