Owners of Xiaomi Redmi 10 often face a shortage of built-in storage, especially if the model is equipped with 64 GB of memory. Installing heavy games, social networks and instant messengers quickly fills the available space, making the system run slower. The solution may be to use a microSD card, but the standard shell MIUI does not always allow you to simply transfer data.
There are several ways to do this, from standard Android settings to advanced methods using USB debugging. It is important to understand that not all applications support external storage due to Google's security limitations. However, it is quite possible to free gigabytes in internal storage if you know the right algorithms of actions.
In this article, we will discuss how to set up a memory card as an extension of internal memory or as a file storage, learn about the risks associated with using third-party software, and get step-by-step instructions to safely optimize the operation of your device.
Preparation of a memory card and smartphone
Before you start any manipulations, you need to make sure that your microSD card meets the speed requirements. For comfortable application operation, it is recommended to use Class 10 or UHS-I cards. Slow drives can cause “freezes” in the interface and long downloads of programs.
Insert the card into a slot located on the end of the Redmi 10 case. Use the original paper clip or special key that comes with the package. The system must automatically identify the new media and prompt it to be configured. If there is no notification, go to the settings menu manually.
Make sure to back up your important data if you already have files on the card. During the setup process, the system may offer formatting, which will result in a complete cleanup of the drive. Save photos and documents to your computer or cloud storage in advance.
- 📱 Make sure your smartphone is at least 50% charged to avoid shutdown.
- 💾 Check the card for errors by connecting it to the PC through the card reader.
- 🔄 Close all background applications before you start setting up the system.
☑️ Ready for transfer
Standard method of transfer through settings
The safest way is to use the Android functionality, go to Settings, then select the App, find the program you want to move in the list, and click on it.
If the app developer has allowed the transfer, you will see the active "Change" button in the "Storage" section. SD-The system will automatically transfer files and the application will take up less space in the internal memory.
Unfortunately, many modern programs like WhatsApp or Instagram don't have this option. In such cases, the button will be inactive or absent.This is a limitation of the operating system itself, not a defect of your Xiaomi.
⚠️ Note: After the application has been moved to SD-widgets and shortcuts can disappear temporarily from the desktop. Just restart the device so that the system updates the indexes.
💡
If the transfer button is inactive, try first clearing the app cache in the Storage menu and then checking the feature's availability again.
Use of the function "Memory Expansion"
The MIUI shell on Redmi 10 has a useful feature that allows you to use the memory card as part of your internal storage, which doesn't carry the applications themselves, but frees up space for installing them by transferring media files and cache of the system.
Activate this option in Settings → About Phone → Memory. The system will prompt you to format the card. Remember that after that, the card will only work with this phone and will not be read on a PC without re-formatting.
This method is the most stable for everyday use, does not require superuser rights and minimizes the risk of damage to system files, and the speed of a smartphone when using fast cards is almost not affected.
| Parameter | Standard transfer | Expansion of memory |
|---|---|---|
| Impact on the guarantee | No. | No. |
| Difficulty | Low. | Medium |
| Risk of data loss | Minimum | High (when formatted) |
| Compatibility | Depends on the app. | Complete. |
Advanced Method through ADB (without Root)
For power users, there is a way to force them to move over the Android debugging bridge (ADB), which bypasses the limitations of application developers, and you need a computer and a USB cable.
Turn on the developer mode on your phone. To do this, quickly click on the build number in the About Phone menu seven times. Then activate USB Debugging in the advanced settings.
Connect your smartphone to your PC and start the command line with administrator permissions. Enter a command to check the connection:
adb devicesAfter confirming the connection on the phone screen, enter a command to change the default installation mode:
adb shell pm set-install-location 2A value of 2 indicates the priority of the external card, a value of 0 returns automatic selection, and 1 returns only internal memory. After applying the changes, try reinstalling or updating the desired application.
⚠️ Attention: Use ADB-A syntax error can cause the system to run in an unstable way, although a return to factory settings usually solves the problem.

Working with file managers
Even if the application itself cannot be ported, its heavy data can often be moved manually, with built-in MIUI Explorer or third-party solutions like Total Commander allowing you to change the way files are saved.
Find the folder of the application you want (e.g. Android/data/com.example.game) If you have a folder inside that has cache or downloaded files, you can move it to a memory card, but some programs will stop seeing data if you change paths.
For multimedia applications like Telegram or Viber, it is better to change the settings inside the application itself. Go to the Data and Memory section and specify the way to save the app. SD-This is the safest and most effective method.
- 📂 Use the “Cleanup” function in the conductor to search for duplicates.
- 🗑️ Regularly delete the thumbnails folder that grows over time.
- 📸 Set the camera to save the photo directly to the memory card.
💡
Moving only user data (photos, music, documents) is safer for system stability than transferring application system files.
Possible problems and solutions
After you migrate applications, you may find that programs are slower, because of the slower read/write speed of the memory card compared to the internal flash memory of the smartphone, and the solution is to use A2 (Application Performance Class) cards.
Another common problem is that widgets disappear, so if you've lost your watch or weather widgets after you've moved them, try removing them and adding them back from your desktop, and rebooting your device also often helps restore shortcuts.
If an application crashes after transfer, it is critically dependent on the internal drive speed, in which case the only solution is to return the application to internal memory, making room for deleting other, less important files.
