How to transfer all data from your phone to your Xiaomi memory card

Xiaomi’s current smartphones, despite their abundance of internal memory, often face a shortage of internal memory due to the growing volume of media files and “heavy” applications. Owners of devices equipped with a microSD slot have the unique opportunity to expand the physical space for storing information without buying a new model. Proper file streams allow you to free up valuable gigabytes of internal memory, which is critical for the stable operation of the MIUI or HyperOS operating system.

The migration process requires careful attention, because there are several methods of transfer, each with its own characteristics and limitations. Some applications allow you to move your cached data to an external medium, while others are strictly tied to the system partition. Understanding the structure of the Android file system is the first step to competent management of resources of your gadget.

In this guide, we will go into detail all the ways you can transfer photos, videos, documents, and even parts of applications, and you will learn how to turn a regular flash card into a full-fledged extension of internal memory or use it as a portable storage. Data security is paramount in these operations, so we will focus on the backup procedure.

Preparation of memory card and compatibility check

Before moving files, make sure your microSD card is fully functional and meets the smartphone’s requirements. Using poor-quality or fake drives can lead to data loss and reduce the overall speed of the device. It is recommended to use UHS-I or UHS-II speed cards from trusted manufacturers.

Put the card in the slot and wait for the system to notify you. If the card was previously used on another device, Android may suggest formatting it. There are two main modes of operation: as portable storage and as internal memory, the choice depends on your goals: transfer only media files or full integration of the card into the system.

To format, go to the settings menu. Navigation is usually as follows: Settings → About Phone → Storage. Here you will see a list of available drives. Select your memory card from the list.

💡

Use memory cards up to 512 GB for maximum compatibility with Xiaomi mid- and budget smartphones released in the last 3 years.

When formatting, it's important to understand the difference between modes. Portable Storage makes it easy to retrieve the card and transfer it to other devices, but it doesn't allow apps to be transferred there. Internal Storage Mode encrypts the card, making it unusable on other phones, but allows the system to use it to install programs.

Storage settings: internal or portable memory

Choosing the type of storage is a fundamental decision that will affect how your phone will work with new files. If you choose to use the card as internal memory, Android will combine the built-in storage space and the storage space. SD-maps into a single logical volume.

This method is especially useful for devices with a small amount of internal memory (for example, 32 or 64 GB). However, it is worth considering that the read and write speed of memory cards is often lower than that of embedded eMMC or UFS chips. This can lead to a slight decrease in the speed of running heavy applications whose data has been moved.

If you choose the portable drive mode, the card will work as a separate disk, you can manually move photos, videos and music, but the applications will be installed by default in internal memory, switching between these modes is possible, but requires full formatting, which will delete all data on the map.

To switch the mode, perform the following actions:

• 📱 Go to Settings. → Memory and choose yours. SD-map.
• 🗑️ Click on three dots in the corner of the screen and select "Format".
• ⚙️ In the menu that appears, select the desired type of use (Internal or Portable).
• ✅ Confirm the action and wait for the initialization process to be completed.

Once you have completed the setup, the system will create the necessary hidden folders to host the application data, and if you have chosen internal storage, the system may suggest that you move the existing data immediately.

Transferring photos and videos through a standard conductor

The easiest and safest way to free up space is to move media files. Xiaomi Gallery and standard file manager MI File Manager allow you to do this quickly and without third-party software. Photos and videos often take up to 80% of user memory, so porting them gives instant results.

Open the Explorer app on your device. You need to find the DCIM folder that saves your camera images by default, and the Pictures or MIUI folder that stores screenshots and images from messengers. Select the desired files or entire folders by holding your finger on one of the elements.

After selecting, click the "More" button or three dots on the menu and select "Move" (not "copy" so as not to duplicate data or take up space twice). SD-You can create a new folder, like this, Archive_Photo_2026, keep order.

When moving large amounts of data (tens of gigabytes), the process can take considerable time. Do not remove the card or turn off the phone until the notification of completion of the operation appears.

Transfer of applications and games to SD-map

In modern versions of Android and the MIUI shell, the ability to fully port applications to an external medium is limited to developers for security and stability reasons. However, for many games and programs, the "Move" function is still available if the card is formatted as internal storage.

To check for portability, go to Settings → Annexes → All applications. Select the desired program from the list. If transfer is possible, the button Move to SD-If the button is grey or missing, the developer has banned it.

There is also the option to transfer only the app cache, which often takes up more space than the installation file itself. To do this, in the application management menu, look for Memory and click Clear or Change (if available). Some third-party file managers, such as Link2SD, require root rights to be forced to port, but this can disrupt the system.

It's important to be aware of the risks. If the memory card fails or is retrieved, the applications that are moved to it will stop running and their data may be lost, so it's better to leave critical programs like bank clients or instant messengers in internal memory.

Automatically save new data to the map

To avoid manual file sorting in the future, it is advisable to set up automatic storage of new data immediately on the memory card, which will eliminate the need to regularly clean the built-in drive.

First, set up the camera. Open the Camera app, click on the three bars in the corner of the screen and select Settings. Find Save to.. or Save Path and select yours. SD-Now all new photos and videos will be recorded directly to external media.

You can do the same for a voice recorder and some video editors. In a browser (such as Chrome or Mi Browser), you can also specify the default path in the download settings, find the Downloads section and change the save folder to your card directory.

⚠️ Warning: When activating auto-save, make sure the memory card is installed securely.Accidental drop-down of the card while recording high-resolution video (4K) This will cause damage to the file and the inability to reproduce it.

For instant messengers like WhatsApp or Telegram, the path to media files changes through the internal settings of each application separately. → chat → A storage facility where you can choose to use SD-map.

Solving problems and errors when working with SD

Users often experience a situation where the phone stops seeing the card or gives a "damaged" error, which may be due to improper extraction, file system or physical wear of the drive. The first step should always be to try to reboot the device.

If the phone offers to format the card, but you do not want to lose data, try connecting it to the computer through a card reader. Run error check with Windows (PCM on disk → Properties → Service → Check). The file system should be exFAT for cards larger than 32 GB.

A common problem is that the camera can interrupt video recording, which indicates that the card speed class is too low for modern standards, and only replacing the drive with a more productive one will help.

💡

Most reading errors are solved by formatting the exFAT card directly with the smartphone, not the computer.

Also worth checking the contacts in the card slot. Dust or oxidation can disrupt the connection. Gently blow the slot or use a soft brush to clean. If the card is not detected on any device, chances are it has physically failed.
