Owners of budget and mid-budget smartphone models often face a lack of built-in storage. Modern mobile applications and gaming projects require more gigabytes, and the standard 64 or 128 GB is no longer enough for a basic set of software. This is especially true for users who prefer heavy duty. 3D-shooters or high-resolution simulators, and when the memory is full, the system starts to run slower, and new applications simply refuse to install.
Fortunately, the Android ecosystem provides flexible tools for managing files, and the shell. MIUI or HyperOS on Xiaomi devices allows you to efficiently use external drives. SD-The cards can be a lifeline for smartphone owners with little internal memory. In this article, we will examine all available methods of data transfer, including hidden developer functions and third-party utilities.
Before you start manipulating, it's important to understand that not all games support direct porting to an external medium. Developers often limit this option for security or stability reasons, but there are workarounds to get the system to consider the external card as part of the internal storage, which requires careful attention and compliance with all the steps of the instructions.
Preparation of a memory card and smartphone
The first and most critical step is to choose a quality storage device. Cheap memory cards from marketplaces often have understated performance and low write speed. For modern games that require fast loading of textures, you need a speed class at least 10 or UHS-I. Using a slow card will lead to long loads of levels and friezes during the game.
Before installing on your smartphone, make sure to check the drive for errors.Put the card into your computer and run a standard disk check utility or use specialized software like H2testw. This will help identify broken sectors and real capacity. If the memory card is defective, it can damage the file system of your Xiaomi Redmi at any time.
💡
Use memory cards up to 256 GB for maximum compatibility with mid-range smartphones, even if the specification claims to support larger volume.
Once you've checked, you can insert the card into your device's slot, and the system will offer you a few uses: portable storage or internal memory, and for our purposes, we'll need the second option that allows you to install the application on the map, but before that, you need to format the media, which will delete all the data on it.
- 📱 Make sure your smartphone is at least 50% charged before formatting.
- 💾 Make a backup of important files with SD-Cards to the computer or the cloud.
- 🔒 Remove the card correctly through the settings so as not to damage the file table.
Basic configuration through the system menu
The standard MIUI interface allows you to change the default save location for some types of files, but for games, this process is hidden deeper. You need to go to the settings menu and find the storage partition. The path may vary slightly depending on the shell version, but the logic remains the same.
Open Settings, then scroll down to About Phone, and click on MIUI multiple times to activate Developer Mode. Then go back to the main settings menu and find Advanced Settings, which is where key options for working with memory are hidden.
In the Advanced Settings section, select Memory. Here you will see information about internal storage occupation and settings. SD-Click on the name of your memory card. If you haven't previously set it up as an internal memory card, the system will suggest formatting it. Accept the warning and wait until the process is complete.
After formatting, you'll see the option "Use as internal storage," which will bring together the phone's memory and the cards into a single space, which is the best way to get new games to download right to the external drive, but remember that after that, the card will be encrypted and will not be read on other devices without re-formatting.
Using a Developer Mode for Forced Transfer
Even after you set up the map as internal memory, some apps may ignore this and only require you to install it in the internal partition, and this is where the Android developer's hidden menu comes in, and it allows you to force you to change the priority of installing apps.
To access these settings, go back to Settings → Advanced Settings → Developer. In the long list of options, find “Preferred Installation Location”**. The default is “Automatic” or “Internal Memory.”
☑️ Developer setting
Change the value to "External Drive" or «SD-After that, any new app you try to download from Google Play or GetApps will default to an external medium, and if there is no such option, the system will try to place the game cache there.
⚠️ Warning: Forced transfer of system applications or mission-critical services can cause a smartphone to run unsettled.Replace priority only for gaming apps and multimedia.
It is worth noting that after the device is rebooted, the developer’s settings can be reset depending on the Android version, in which case the procedure will have to be repeated, and some heavy games with additional cache can still take up space in internal storage, since some of their files must be loaded into RAM at maximum speed.
Working with file managers and cache
Often, the app itself is installed on the map, but its heavy cache is left inside. In games like PUBG Mobile or Genshin Impact, the cache can take up tens of gigabytes. You can move it manually using the built-in Explorer or a third-party solution like Total Commander.
You need to find a folder with game data, which is usually located along the path. Android/data/ or Android/obb/. Copy the folder with the name of the game package (for example, com.tencent.ig) on SD-Once you delete the original, create a symbolic link, but that requires root rights that most users don't have.
A simpler method is to use the movement function in the application settings. Go to Settings. → Annexes → All apps. Find the game you want in the list. If you can move it, the Change button will be active. SD-map.
| Type of data | Default location | Possibility of transfer | Impact on speed |
|---|---|---|---|
| APK file (installer) | Internal memory. | Yeah (when setting up) | Minimum |
| Cash games (OBB) | Internal memory. | Partially. | High (card speed is important) |
| Conservation | Internal memory. | Rarely. | Low. |
| Downloaded maps | Depends on the game. | Yeah (in game settings) | Average. |
Why is the “Move” button inactive?
Android compatibility issues and limitations
Since Android 6.0, Google has introduced Adoptable Storage, which allows the card to be used as part of the system. However, many manufacturers, including Xiaomi in some regions, hide the feature or limit it, so that users do not complain about the slow operation of the device because of cheap memory cards.
If standard methods fail to activate internal memory, you can try using commands via ADB (Android Debug Bridge), which requires connecting your smartphone to your computer and having basic command line knowledge, and allows you to force the function hidden by the manufacturer to turn on.
To do this, you need to enable debugging via USB in the developer menu, connect the phone to the PC and enter the command adb shell sm partition list to determine the disk, and then adb shell sm partition private disk:XXX mixed. Be extremely careful: incorrect execution of the command can lead to complete loss of data on the map and the need to flash the phone.
- 🛑 Do not remove the memory card while the phone is on if it is formatted as an internal one.
- ⚡ Random card reading speed is more important than linear write speed for games.
- 🔄 Periodically check the integrity of the file system of the card through the settings.
⚠️ Attention: Use of teams ADB To change partitions, the memory cancels the software warranty and can cause the device to “brick” when errors occur.
Optimization and maintenance after the transfer
After the games were moved to SD-The memory memory has a limited rewrite life, active play with constant saving of progress and loading of assets wears out the card faster than usual storage of photos.
It is recommended to defragment once a month (although modern file systems do this automatically, check it will not hurt) and back up important data. If you notice that games have started to load longer or artifacts appear, perhaps the memory card has begun to crumble.
💡
Regular health check-ups SD-cards prolong life not only by your saves, but also prevents failures in the operation of the entire Xiaomi operating system.
It is also worth considering that when resetting the phone settings to factory (Wipe Data), the data on the SD-A card formatted as an internal memory will be lost or unreadable. Always back up before radical action.
