How to transfer games to Xiaomi memory card: the complete guide

Owners of Xiaomi, Redmi and POCO smartphones often face a situation where built-in storage is overcrowded. Heavy gaming projects like Genshin Impact or Call of Duty Mobile take tens of gigabytes, forcing users to delete old apps or clean cache. Transferring data to an external drive becomes not just a convenience, but a necessity for comfortable use of the device.

However, modern versions of the MIUI and HyperOS shell have their own features in working with the file system. Simply moving folders is often not enough, since Android security system restricts access to external media without special settings. In this guide, we will discuss proven methods for expanding game memory.

It is worth noting that the speed of games can depend on the class of the memory card. Using slow drives can lead to long loads of levels. So before starting the procedure, it is important to make sure that your MicroSD module meets the requirements of modern mobile applications.

Preparation of a memory card and smartphone

Before you start transferring data, you need to properly prepare the external drive. Using a poor-quality or damaged card can lead to loss of progress in games or even to a system freeze. Make sure your smartphone supports MicroSD installation, as many flagship Xiaomi models lack a slot for expanding memory.

It is recommended to format the card in the file system that Android recognizes best, usually exFAT or FAT32, although modern versions of the system may offer their own encryption. If the card has been used in other devices, it is better to back up important files to your computer.

Put the card in the smartphone turned off or use a hot replacement if your model allows. After turning on the device, go to Settings → About Phone → Storage. The system should automatically prompt you to format the new drive. Choose the use case as portable storage if you plan to move the card to other devices often, or as internal memory for maximum integration.

⚠️ Note: Formatting a memory card will completely destroy all data on it. Pre-save photos and documents if there is already something on the card.

Read and write speeds directly affect how fast textures load in games. 3D-The minimum standard is the speed class. UHS-I ormarking A1/A2.

Standard method of transfer through settings

The safest and easiest way to move games is to use Android’s built-in functionality, which requires no third-party software and works consistently on most devices, but is not available for all applications, as game developers can block the movement of their products.

To start, open the settings menu and find the App section. From the list of installed programs, select the game you want to move. If the application supports portability, the Change or Memory button will be active. Click on it and select the move option on the app. SD-map.

The process can take from a few seconds to a few minutes depending on the size of the cache and the game data. During the transfer, it is not recommended to run other heavy applications or make multitasking switches.

If the transfer button is inactive or absent, then the developer has banned this operation, in which case the standard methods will not work, and you will have to resort to more complex technical solutions or to accept internal memory.

• 📱 Go to Settings. → Annexes → All applications.
• 📂 Select the desired game from the list.
• 💾 Press Memory and select Change.
• 🔄 Confirm the transfer to the map SD.

Once the procedure is complete, the app shortcut will remain on the desktop, but the files will physically be located on an external medium, freeing up precious space in the system partition.

Use of Adoptable Storage

Adoptable Storage allows Android to think of the memory card as an extension of internal memory, which is the most effective method for Xiaomi owners with a small amount of internal storage, in which case the system decides where to download new games and data.

To activate this feature, when formatting a map, you need to select the option Use as internal storage, the system formats the card in its own format and encrypts it with a specific device, and then you can't just take the card out and paste it into another phone without losing data.

This approach provides better performance as the operating system optimizes file placement, and heavy games will automatically be installed on the fast sector of the card or internal memory depending on the MIUI algorithms, but the speed will still depend on the characteristics of the memory card itself.

It’s important to understand that not all Xiaomi smartphone makers include this option in the menu by default. In some regions and firmware versions, it’s hidden. If you don’t see the “Use as internal storage” option, your model may not support this feature at the software level.

Transfer data through the file manager

For advanced users, it is possible to manually move the cache of heavy games, a method often needed for games with large additional files (OBB-files that are not portable by standard means.You will need a file manager with permissions to access system folders, such as Total Commander or Mi File Manager.

First, find the folder with the game in internal storage. It's usually located on the Android/obb or Android/data path. The folder name often matches the batch name of the application, for example, com.tencent.ig for PUBG. Copy this folder to the memory card in a similar directory structure.

Once you copy, you need to make sure that the game "sees" new files. In some cases, you need to create a symbolic link, but on smartphones without Root rights, this is difficult to do. The simpler option is to specify the game itself (if there is) to specify the path to resources or simply delete the original files from internal memory, leaving them on the map.

Be careful when manually deleting files from system folders. A name error or deleting an extra file can cause the game to stop running or require re-uploading data.

• 📁 Open the file manager and go to internal memory.
• 🔍 Find the file. Android/obb.
• ✂️ Cut out the folder with the game data.
• 📥 Put it in. SD-map/Android/obb.

This method is especially effective for older versions of Android or games that don’t know how to determine the path to the cache on an external medium. However, on Android 11 and later, access to the Android folder is limited, and you may need to provide special permissions to the file manager.

Compatibility and Limitations Issues MIUI

MIUI shell is known for aggressive memory optimization, which sometimes creates conflicts when working with external drives. Users may face a situation where the game is working normally, but after restarting the phone stops seeing files on the map.

Another common problem is desynchronizing the path to files, and once you update the system or the game itself, the paths may change, and the application will require you to download the data again, in which case cleaning the application cache or resetting the paths in the settings helps.

It is also worth considering that some anti-cheat systems in online games can block the launch of the application if they find that the game files are located on an external drive.

⚠️ Note: If the game crashes when it starts after transfer, try to return the files back to internal memory.

To solve access problems, sometimes rebooting the device after every significant change in the file structure helps, allowing the system to re-index the contents of the memory card.

💡

If the game stops seeing saves, check in the phone settings to see if the "Show Hidden Files" option is enabled in the file manager. Sometimes save folders have a hidden attribute.

Optimizing performance after transfer

After the games are transferred to the memory card, it is important to monitor its state. File fragmentation can reduce the speed of reading over time, it is recommended to defragment (if the file manager supports) or simply check the speed of the drive with special utilities.

Make sure there is always room on the memory card, fill the external drive to the end, and then you'll see a sharp drop in the performance of the entire system, and try to keep at least 15-20% of the total card free.

If you notice that games are loading longer than before, the memory card may have run out of write speed, so the only solution is to replace the drive with a more modern and faster one.

Check drivers and the MIUI system regularly. Xiaomi engineers often release patches that improve compatibility with various memory card models and optimize the file system.

• 🧹 Clean the game cache once a month.
• 📈 Keep an eye on the card (no more than 90%).
• 🔄 Make backup copies of saves to the cloud.
• 🛡️ Use antivirus to check external files.

💡

Regular maintenance of the memory card extends its life and ensures a stable FPS in games.
