How to transfer cache to OBB folder on Xiaomi: a guide

Xiaomi smartphone owners often face a shortage of internal memory, especially on models with a basic configuration. 64 GB: The Android system is becoming increasingly trashy over time, and heavy gaming requires more and more resources to store temporary data. It is in these situations that users begin to look for ways to optimize, and one of the popular, although not always correctly understood requests is to transfer the cache to the folder. Android/obb. Many people confuse the concepts, believing that moving files manually will speed up the device or allow you to install games that do not fit into the standard structure.

Actually, the file. OBB (Opaque Binary Blob is designed by developers of applications for storing large data files that cannot be packaged into the main file. APK-file due to Google Play restrictions. on Xiaomi shell devices MIUI or HyperOS, the file permission structure has become stricter, especially since Android 11 and up. Access to system directories is now limited, and simply dragging files through standard Explorer may not work or cause app errors.

In this article, we'll explore whether it's really worth interfering with this directory, how to manage space properly, and what tools will help you clean up your messaging. You'll learn how app cache differs from OBB data, why games stop running when you manually move files, and how to safely free up space without compromising system integrity. Understanding file structure is key to managing your gadget's memory properly.

Difference Between App Cache and OBB folder

Before you start any action with the file system, you need to understand the terminology clearly. Application cache is a temporary file that programs create to speed up their work. This can be thumbnails of images, temporary logs or intermediate data. These can be deleted without harming the functionality, although the next time the application starts, it will create them again, which can take time.

Unlike a temporary cache, the OBB folder contains critical data. It uploads textures, music, levels and videos from games. If you delete the contents of this folder, the game simply won't start or requires re-uploading gigabytes of data. On Xiaomi smartphones, this directory is usually on the /Android/obb/ path and is tied to a specific application package.

⚠️ Note: Manually moving files from cache to OBB or vice versa without the use of special tools often leads to violation of checksums.

Users often try to trick the system by transferring data to a memory card or other partitions to make room. However, modern versions of Android on MIUI tightly tie the path to the application data. If a game expects to find textures at a specific address, and you moved them, it will give an error. So talking about “transferring cache to OBB” as an optimization method is not exactly correct — it is more correct to talk about competent management of these partitions.

📊 Where do you most often run out of space on Xiaomi?
Internal memory.
SD Memory Card
Application memory
System section

Why is it necessary to transfer data?

The main reason users are looking for ways to manipulate the obb folder is a banal lack of free space: Heavy games like Genshin Impact, PUBG or Call of Duty Mobile can take up more than 10-15 GB. When internal memory is filled, the system starts to run slower, and new applications stop being installed.

The second reason is that some launchers and modified versions of games work, and sometimes users want to run a game that has data on an external drive, but Android 11 is a game that is not a game that is not a game that is a game that is not a game that is a game.+ Blocks direct access to the Android folder on SD-This creates a situation where the files seem to be there, but the application does not see them».

There is also the problem of data duplication: When you reinstall applications or use different versions of the same software (eg global and Chinese), the storage can remain “orphaned” folders with data that take up space but are not used, cleaning them is a safe way to return gigabytes of memory.

  • 📉 Overflow of the system partition leads to interface brakes MIUI.
  • 🎮 Games require heavy files to be placed in internal memory for fast loading.
  • 🔄 Errors when updating applications are often associated with a lack of space in the directory OBB.

Instructions: Managing OBB files through file manager

To work with system folders on Xiaomi, you will need an advanced file manager, since the standard Explorer can hide some system directories or not have rights to write in them. The most popular and reliable solution is the MT Manager or ZArchiver application, which allows you to work with archives and system folders with increased privileges.

The first step is getting the permissions you need. On Android 11, 12, 13 and later, when you try to open your Android folder, the system will issue a security alert, and you will need to click "Allow" and confirm access to the files by going to the special access settings, without which any manipulation will be impossible.

☑️ Preparation for working with the file system

Done: 0 / 4

The algorithm of actions is as follows:

1. Open the file manager and go to the root of internal memory.

2. Find the Android folder, then the obb.

3 Inside, you will see folders with packet names (e.g., com.tencent.ig).

4 If you want to transfer the game from the memory card (if it was there), copy the contents of the corresponding folder from here to /Android/obb/ on internal memory.

⚠️ Note: Do not rename packet folders (e.g. com.game.name). If the folder name does not match the application packet name, the game will not find its data.

It's important to understand that you can't just move the cache of any application to OBB. The structure has to be consistent with the program's expectations. If you want to transfer the entire game to a memory card (to free up internal space), modern versions of MIUI can't do that with regular means - the system forcibly keeps all game data in internal storage for performance.

What to do if the Android folder is hidden?
In some versions of MIUI, the Android folder may be hidden by default. To see it, open the file manager settings and turn on the "Show hidden files." If that doesn't work, use a third-party manager like Total Commander with a LAN plugin or Root access.> Using special utilities and ADB To work deeper with the file system, especially if standard methods don't allow access to the desired partitions, you can use the ADB (Android Debug Bridge) toolkit. This method requires connecting the smartphone to the computer and enabling USB debugging in the menu "This is a more secure way to move files to the interface from the other layer, it works by bypassing the system, or bypassing the ADB. But for the average user, it can be a bit tricky, and the simpler option is to use cleaner applications or managers that tend to work in Shizuku mode, a service that allows ordinary applications to gain advanced rights without root access. adb shell pm grant com.zdev.zarchiver android.permission.MANAGE_EXTERNAL_STORAGE This allows you to assign the file manager the status of the owner of the storage, and then you have full control over the data and obb folders. This is especially true for owners of Xiaomi Redmi and Poco, where security policies can be quite aggressive. 💻 ADB allows you to execute commands directly, bypassing the graphical interface. 🔐 Encrypting data on new Android prevents simple file copying. 🛠 Shizuku Service – a modern alternative to root rights for file management. Instead of riskier file transfers, often a better solution is a quality cleanup. MIUI There's a built-in Security app that allows you to clear the cache, but it works superficially. For deep cleaning, you'd better use specialized ilets that can find residual files in the obb folder from games that have already been deleted. Android/obb You can have folders from games you deleted months ago, they can take up a few gigabytes. You can manually check the folder list, and if you see a title that's not on your device, you can delete that folder, and that will make room for the system. You also have to pay attention to the cache of social media, apps like Telegram or something like that. VK Can cache gigabytes of video and photos. They are better cleaned through the settings of the applications themselves, choosing the option "Clear cache", rather than manually deleting files through the explorer, so as not to disrupt the message database. /data/data/.../cache Yes (via settings) Startup acceleration, resetting Data OBB /Android/obb/ Only from remote games the game will stop working without data /data/local/tmp Yes Safe Logs of the system /data/log/ When trying to optimize memory, users often make mistakes that lead to unstable smartphone operation. The most common is the removal of folders with unknown names in the system directories. On Xiaomi, many folders have complex names related to system services. Deleting them can lead to an endless bootloop. Another mistake is trying to transfer the obb folder entirely to the memory card by changing the symbolic links, which on modern versions of Android is almost guaranteed to result in no game being able to read its data. The security system will simply block the application from accessing external media to execute code or read resources. ⚠️ Note: If after manipulating files, the game gives off a black screen or crashes, do not rush to reinstall the system. Try to completely delete the game, clear the obb folder of its residues and download again. If you encounter an error "Insufficient Memory" when installing, even though there is space, try clearing the Google Play Store's cache. → Annexes → All applications → Google Play Store → Warehouse → Clear the cache. This often solves the problem of stuck downloads. 💡The safest way to free up space is to remove unused apps and clear the messenger cache, not manually edit system folders. OBB. To sum up, “transferring cache to obb” is more of a myth than a workbook for Xiaomi’s acceleration.The obb folder is a strictly designated place for these games, and it’s not a universal repository for any junk. Competent memory management consists of regularly reviewing installed applications and using quality cleaning tools. Don't try to fool the Android file system by moving files to where they shouldn't be. MIUI. Better use cloud storage for photos and videos, and leave internal memory for the system and active applications. Remember that modern Xiaomi smartphones have quite smart memory management algorithms, and interference with their work is rarely required. If the phone started to work slowly, most often helps a complete reset (with a preliminary backup) or a banal lack of physical memory, which is no longer solved by software methods. FAQ: Frequently Asked Questions Can I Move the Folder? OBB Android memory card 12/13? No, not with regular means.
