Xiaomi and Redmi smartphone owners often face a lack of built-in storage, especially if the device has 32 or 64 GB of memory. After installing several “heavy” applications and modern games with high-quality graphics, the free space is rapidly running out, which leads to a slowdown.
Unfortunately, in modern versions of the MIUI and HyperOS shells, the standard feature of transferring applications to a memory card is often hidden or completely absent from the settings menu, which is done by manufacturers to ensure stability, since microSD card reading speeds are usually lower than those of embedded flash memory. However, there are proven methods to circumvent these limitations and use the external drive more efficiently.
In this article, we’ll look at the technicalities of working with the Android file system, look at secure ways to transfer data without obtaining root rights, and discuss the risks associated with formatting a map as internal storage. You’ll learn what tools really work in 2026 and how to properly prepare your device for modification.
Why Xiaomi is hiding the function of porting applications
Many users mistakenly believe that the lack of a “Move to” button SD-The map is a bug or an omission by engineers, and it is actually a deliberate decision by Xiaomi, driven by Google's demands and the way modern processors work. Standard Android allows you to transfer only the cache and part of the application resources, leaving executable code (.apk) and important databases in internal memory.
The main reason for the limitations lies in the speed of access to data: built-in memory such as UFS 2.1 or UFS 3.1 provides significantly higher reading and writing rates compared to most microSD cards. If you move heavy play to a slow card, you will encounter long level loads, friezes and possible application crashes.
In addition, the company cares about the security of user data: applications installed on internal memory are encrypted and isolated by the system, transferring them to an external medium that can be easily retrieved and connected to a computer creates a potential vulnerability to confidential information.
⚠️ Warning: Attempts to force hidden features through an engineering menu can lead to unstable system operation.Be careful when changing system flags.
Despite these limitations, the need for memory expansion has not gone away, and users are finding workarounds, one of which is the use of Adoptable Storage mode, which turns the memory card into a full-fledged extension of internal storage.
Preparation of SD-card and smartphone for work
Before you start any manipulation of the file system, you need to make sure that the equipment is serviceable and compatible. Not every memory card is suitable for installing games, especially if we are talking about modern three-dimensional open-world projects. Reading speed should be at least A2 for comfortable work.
First, back up all the important data on the map. The process of preparing for games often requires complete formatting, which will lead to the permanent removal of photos, music and documents, save them to your computer or to the cloud.
Put the card in the slot and wait for the system to recognize it. Go to the Settings menu → About phone → Storage. If the system suggests formatting the card as “Internal Storage”, you are lucky — this is native support for the function. If there is no such item, you will need to use third-party software.
- 📱 Make sure that the smartphone is enabled debugging USB menu "For developers».
- 💾 Use cards from 32 GB, as a smaller volume is not advisable for gaming.
- 🔋 Check the status of the battery as the formatting process is energy intensive.
It’s also worth checking whether your particular Redmi or Poco model range supports ext4 or f2fs file systems, which are required to function properly as a system partition.
Adoptable Storage: Turning a card into internal memory
The most effective way to address space shortages is with Adoptable Storage, which allows Android to consider an external map as part of an internal partition, encrypt it, and install the entire application, not just its cache.
To activate this feature on Xiaomi devices, you often need to enter a special command via a computer or use a terminal, USB-cable and installed drivers ADB. Connect your phone and enter a command to check current drives.
adb shell sm list-disks
Once a disk is detected (usually denoted as disk:179.64 or similar), a formatting command is executed, which will completely destroy all data on the map and make it unreadable for other devices without re-formatting.
What to do if the team is not executed?
If ADB If you can't see the device, check the drivers installed. USB-cable or port. On your phone, select File Transfer Mode when you connect (MTP)» And confirm debugging in the pop-up window. "" Once formatted successfully, the system will suggest moving the data. Choose the option to move all the content. Now, when you install new games, the system will default to offering the memory card as the installation location if the internal memory is occupied. Settings: Adoptable Storage File System FAT32 / exFAT ext4 / f2fs Access from PC Direct Only via phone Installing Games Partial Full Security Low Encryption Using this method makes the memory card unique for this smartphone. You can’t just take it out and paste it into another phone or card reader – the data will not be available without the encryption keys of a particular device. Using third-party utilities for transfer If messing with the command line ADB You don't want to, you can use specialized apps from Google Play. One of the most popular tools is the Google Play app. App2SD or Files2SD. These automates are a process of validation and offer one-click solutions for moving, but it is worth understanding the limitations: without root rights, such applications can only move cache or create symbolic links if the system allows. On newer versions of Android (10, 11, 12 and above), the capabilities of such programs are severely limited by Google's security policies. Some file managers, such as MiXplorer or Total Commander, also have plugins to work with the software. SD-card. They allow you to manually transfer folders with the game cache (for example, obb folders and data from the game cache). Android/), But this often leads to startup errors, as applications search for files in strictly defined paths. 🛠 Download apps only from verified sources (Google Play). 🚫 Avoid programs that require strange permissions immediately after installation. 🔄 Regularly update utilities for compatibility with new security patches. Third-party utilities are highly dependent on the processor model and firmware version. On devices with MediaTek processors, unlocking the feature is often easier than on Snapdragon. Instructions for many heavy games, such as PUBG, Genshin Impact or Call of Duty Mobile, the bulk of the volume is not occupied by installation files, but cache with textures and resources. You can try to move it manually, although modern versions of Android actively resist it. First, find the folder with the game's cache. It's usually located along the way. Android/obb/ or Android/data/. The folder name often matches the name of the application package, such as com.tencent.ig. Copy this folder to a memory card. ⚠️ Note: When manually transferring data and obb folders, the game may stop running or require re-loading resources. Do this only if the internal memory is critically filled. After copying, delete the original folder from the internal memory to free up space. If the game starts correctly, it works, otherwise you will have to return the files back or use the "Connect" function in root-access file managers. 💡Use the “Symbolic Link” feature in root-right file managers. This will create a bridge that will redirect game requests from internal memory to the map automatically, and some users create scripts to automatically transfer each time a new game is installed. This requires programming skills and an understanding of the Linux structure on which Android is based. SD-The main drawback of this card as a system memory is that it reduces the overall speed of the smartphone when you write or read data actively. If you run a game from a card, the loading time of the levels can increase in the game. 2-3 Memory cards have a limited resource for overwriting cells. Active work with game databases and cache quickly wears the drive. Unlike internal memory, external cards do not have complex wear-alignment controllers, so they can fail through the use of external cards. 6-12 months of active operation. 📉 Decline FPS and performance in heavy games. 🔋 Increased power consumption due to the constant operation of the card controller. 💥 The risk of data loss in case of sudden extraction or power failure. Also, it is worth considering that when you reset your phone to factory settings (Wipe Data), the data on the formatted internal card will be lost if you do not make a separate backup. 💡SD-A card is a great solution for storing photos, videos and music, but it is better to use internal memory or cloud services to install active games and applications (FAQ) Can I transfer games to Xiaomi without a computer? Yes, you can try through the storage settings, if the manufacturer left this option, or using applications like App2SD. However, full porting through Adoptable Storage without root rights and PC is often impossible on new versions. MIUI. Why did the game stop running after the transfer? Most likely, the file paths were broken or the application does not have permission to read external memory. Try to return the files back or give the application all the requested permissions in the privacy settings. Which memory card is best for games on Redmi? MicroSDXC cards with Class 10 markings will be the best choice, U3 necessarily A2 (Application Performance Class 2. Samsung brands EVO Plus, SanDisk Extreme or Kingston Canvas Go! are doing better. Will the phone reset after formatting the map? No, the phone won't reset, but all the data on the map will be destroyed. If you select the “Move Data” option, the phone may require a reboot to apply file system changes.
