Xiaomi Redmi smartphone owners often face a critical shortage of internal storage, especially if the device is equipped with only 32 or 64 GB of storage. The main “eater” of free space is almost always the WhatsApp messenger, which accumulates gigabytes of media files, voice messages and backups. SD-The card becomes not just a convenience, but a necessity for the stable operation of the operating system. MIUI.
Unfortunately, standard tools such as the simple Move button in the app menu are not always available, due to Android’s security policy, which limits messengers to internal memory only, but there are proven ways to bypass these limitations to effectively use an external drive to store heavy content.
In this guide, we will analyze both the standard features of Settings and advanced methods using ADB-You will learn how to turn a memory card into an extension of internal storage and free precious megabytes to install new programs.
Preparation of memory card and backup
Before you start any manipulation of system files or storage settings, you need to make sure that your system is serviceable and compatible. SD-Using poor-quality drives can lead to the loss of important correspondence or even damage to the database of the messenger. It is recommended to use cards of class speed 10 or higher, since the write speed directly affects the speed of the application.
The most important step is to create a full backup of all data. Even if you plan to just migrate media files, the risk of accidentally deleting chats remains. On WhatsApp, this is done through the Settings menu → Chats → Backup of chats. Make sure the copy is saved to Google Drive or locally on the device before work begins.

Use an original adapter or high-quality card reader when working with SD-a computer card to avoid errors when reading memory sectors.

Once you have created the backup, remove the memory card and connect it to your computer for formatting. The file system must be compatible with Android, usually FAT32 or exFAT. If the card has been used on another device, it is better to complete the formatting to eliminate file table errors.
Transfer media files through WhatsApp settings
The safest and easiest way to free up internal memory is to redirect the storage of new media files directly to the memory card, which is built into the messenger itself and does not require root permissions or a connection to the computer, but it is worthwhile to understand that the application itself will remain in internal memory, and only photos, videos and documents will be left on the external one.
To activate this feature, open WhatsApp and go to the settings menu. You'll need to find the Chats section where Media Visibility is located and the storage settings. Depending on the version of the MIUI shell and the messenger itself, the interface may differ slightly, but the logic remains the same.
If your version of the app doesn't have a direct switch, you can use the system method through Explorer. Find the WhatsApp folder in the internal storage and try to move its contents to the map. Then, in the messenger settings, specify a new path to the media files. The system can request permission to access the files, which must be confirmed.
- 📂 Open the settings inside the WhatsApp app.
- 📂 Go to the Chats section and select “Storage».
- 📂 Click "Change" next to the storage method and select yours SD-map.
- 📂 Wait for the migration of existing files to be completed.
This method is ideal for users who do not want to risk the stability of the system, and it ensures that the application updates are successful and data security is not compromised by the system restrictions of Android.
Use Adoptable Storage feature on Xiaomi
In older versions of the shell MIUI It was possible to use the Adoptable Storage function, which allowed to completely combine internal memory and SD-In this case, the system perceives the card as an integral part of the phone, and all applications, including WhatsApp, can be installed there by default.
On modern Xiaomi Redmi smartphones, this feature is often hidden by developers for performance reasons, since memory cards run slower than the built-in flash memory. However, it is worth checking for this option.Put the card, go to Settings → About Phone → Storage and select your card. If there is a paragraph “Use as internal storage”, you are in luck.
Settings → About phone → Storage → SD- Card → Format as internalOnce this mode is activated, the phone may need to reboot, and all new data and applications will be automatically written to an external medium, which solves the problem of space shortage globally, but makes the memory card tied to a particular device, so you can't read it on another phone without formatting.
| Parameter | Internal memory. | SD-card (as an internal card) | SD-map (portable) |
|---|---|---|---|
| Speed of operation | Tall. | Medium/Low | Depends on the class. |
| Security | Tall. | Encrypts. | No encryption. |
| Transfer to another phone | No. | No (no reset) | Yes. |
| Installation of applications | Yes. | Yes. | Limited. |
💡
Adoptable Storage is a function that converts SD-card in the system section, which allows you to install any applications on it, but reduces the overall speed of the smartphone.
Transfer through ADB: Forced Migration
If standard methods do not work, a debugging tool comes to the rescue. ADB (Android Debug Bridge, which allows you to force the default mount point to change for all installed applications, requires a computer (Windows, macOS or Linux) to implement it), USB-cable and on-line debugging USB smartphone.
First, you need to activate the hidden developer menu. On Xiaomi Redmi, you need to quickly click on the build number in the About Phone section seven times. Then, in the Developer menu that appears, turn on the USB debugging and USB Installation options. Connect the phone to your PC and confirm the trust request on your smartphone screen.
☑️ Preparation for work with ADB
Open the command line on your computer in the ADB folder and type the following command to change the storage settings:
adb shell pm set-install-location 2Here, the number 2 indicates the priority of external storage. After completing the command, all new installations, including WhatsApp updates, will try to fit on the memory card. To return everything as it was, use the command adb shell pm set-install-location 0 (automatic selection system).
⚠️ Attention: Team ADB It doesn't automatically port already installed apps, it changes the behavior of the system only for future installations, and it may require reinstallation of the existing WhatsApp to migrate.
Solving Access Rights and MIUI Issues
MIUI is known for its aggressive energy saving and memory management policies, which often lead to conflicts when working with external drives. If WhatsApp has stopped receiving notifications or downloading media after the transfer, check autorun and permission settings.
Go to Settings. → Annexes → All applications → WhatsApp. Make sure that the "Allowances" section lists all items related to storage, phone and microphone. Also, in the "Battery" menu, select "No Limits" mode so that the system does not "kill" the process of the messenger running with slow SD-card.
A common problem is desynchronizing file paths. If you moved the Media or Databases folder manually, WhatsApp may not see them and create new, empty folders, in which case you need to delete duplicate folders in internal storage, leaving only links or empty directories if the system requires them.
What if WhatsApp says “Not enough space” when the map is empty?
Optimization and maintenance after the transfer
After successful data transfer, you need to regularly maintain the memory card to avoid its degradation. Flash memory has a limited resource of overwriting cycles, and messengers constantly update databases. → Warehouse.
You should also set up automatic garbage cleanup, and WhatsApp itself has a built-in storage management tool that allows you to delete files larger than 5MB or media over a certain period, which will help keep the system on track and prevent sudden crashes when the buffer overflows.
- 🗑️ Regularly remove unnecessary videos from chat rooms.
- 🗑️ Turn off auto-save in groups where memes are often sent.
- 🗑️ Use Google’s Files app to find duplicates.
- 🗑️ Make a full backup to your computer every six months.
Compliance with these simple rules will prolong the life of your Xiaomi Redmi and provide comfortable communication without constant reminders of the lack of space.
