How to transfer data to a memory card on Xiaomi: the complete guide

Modern Xiaomi smartphones offer huge amounts of internal memory, but even 256 or 512 gigabytes can run out at the most inopportune moment, especially if you like to shoot high-resolution video or install a lot of heavy games. Owners of devices with support for expandable memory often face the need to transfer accumulated files to an external medium to make room for the system. This is not just a matter of convenience, but also a way to keep the device running, since crowded storage can slow down the processor.

The process of moving data to MIUI or the new HyperOS has its own nuances, different from standard Android, and requires careful approach to choosing the type of storage. SD-Transfer media and even some applications without losing important data.

Before you start taking action, you need to make sure that your memory card is working and has a sufficient write speed.The cards used can lead to loss of photos and documents, so choose products from proven brands with a speed class of at least Class 10 or UHS-I.

⚠️ Before starting any operations with the file system, be sure to back up important data in the cloud or on your computer, as formatting the map will completely destroy all information on it.

Preparation of memory card and smartphone for work

The first step is to install the drive correctly and initialize it first. Put the card in your Xiaomi SIM card tray, observing the orientation of the contacts, and wait for the notification of the system when the new device is connected. The operating system will automatically prompt you to configure the drive, and here it is important not to click blindly "OK", but to choose the correct mode of use.

Xiaomi offers two main uses for external memory: as a portable storage device to transfer files between devices or as an extension of internal memory. The second option, known as Adoptable Storage, encrypts the card and binds it to a particular phone, making it impossible to read data on other devices without formatting.

For most users, Portable Storage is the best option, which allows you to easily retrieve the card and connect it to your computer through a card reader, but if you plan to store only personal photos there and do not plan to change devices often, you can consider encryption for increased data security.

Configure storage in MIUI and HyperOS

Once you physically install the card, you need to go to the system settings for configuration. Find the Settings section, then scroll down to About Phone, or immediately select Advanced Settings depending on your firmware version. We need the memory management section.

In the storage menu, you'll see a list of available drives where your new map will be displayed. Click on it to open the management menu. The system may suggest clearing the drive, a necessary step to create the right file structure that is compatible with Android.

If you don't get an automatic offer, look for the menu button (three dots in the corner) and select "Storage settings." You can force the card to format. Select the exFAT format if the card is larger than 32 GB, which will support large files.

The formatting process can take anywhere from a few seconds to a couple of minutes depending on the storage capacity, while you do not remove the card or turn off the phone so as not to damage the partition table.

Transfer of photos and videos through the Explorer

The easiest and most reliable way to free up space is to manually move media files. Open the standard File Manager app, which is pre-installed on all Xiaomi smartphones. At the top of the screen, you'll see tabs that switch the view between file categories and folder structure.

Go to internal memory, usually called Internal Storage or Primary Drive. Find the DCIM folder that stores the camera shots and the Pictures folder for screenshots and images from messengers. Select the files you need with a long press.

Once selected, click "More" or "Menu" at the bottom of the screen and select "Move." The system will prompt you to select destination - specify your destination. SD-You can create a new folder or select an existing one, and this method ensures that the original files are physically transferred, freeing up space.

When moving large amounts of data (such as a few gigabytes of video), the phone may get slightly warmer, which is a normal memory controller response to intense recording.

Automatic saving of photos and videos on the map

To avoid manually transferring files every time, you can set up your Xiaomi camera to automatically save your images immediately to the external drive. Open the Camera app and click on the menu icon (three bars) in the upper right corner of the screen.

In the menu that opens, select Settings. Scroll down to the save section to find the Save on switch. SD-map" or "Use the card SD-Now all new photos and videos will be recorded by default in external storage.

It’s worth noting that some shooting modes, such as slow motion or ultra-high resolution (8K) video, can ignore this setting and save to internal memory due to write speed requirements that cheap cards may not provide.

💡

To shoot video in 4K, use memory cards with a write rate of at least 30 MB / s (marked V30), otherwise the video may be interrupted or not saved.

You can also set up a similar feature on popular social media platforms like Telegram or WhatsApp, changing the save path in their internal storage settings if the app supports this feature on your Android version.

Transfer of applications and games to external memory

The issue of transferring installed applications to SD-The card is one of the most complex in the Xiaomi ecosystem. 6.0, Google has limited this capability, and in the shell MIUI/HyperOS It is not possible to transfer most applications by standard means.

However, some system applications and older programs may support this feature. To check for portability, go to Settings → Applications → All Applications. Select the desired program from the list.

If the developer has allowed the move, you will see an active button "Move to the site". SD-The "card" or "Change" section of the "Storage" section, clicking on it, the system will transfer the main part of the application data, leaving a minimum framework in the internal memory for correct operation.

⚠️ Note: Moving applications may run slower, especially if the memory card has a low random read speed (IOPS), What is critical to running programs.

For advanced users, there is a possibility of using ADB-commands for forced transfer, but this requires a connection to a computer and can lead to unstable operation of the system when retrieving the card.

Use of the card as internal memory (Extension)

Regime under which SD-The card becomes part of a system partition called "Memory Extension." When you activate this mode, the system formats the card, encrypts it, and combines it with the internal storage.

To activate this feature, select "Use as internal storage" when you first set up the card. If the card is already formatted as portable, you will need to format it again through the storage settings menu, selecting the appropriate item.

Once activated, the system can offer to transfer existing data and applications automatically, a convenient way for devices with a small amount of internal memory (for example, 32 or 64 GB), allowing you to install more games.

💡

Internal memory mode makes the card unreadable on other devices and ties it to a particular phone forever until you reset your settings.

However, remember that memory cards are usually shorter than a phone’s built-in flash memory, and intense logging can bring the card down faster.

Cache cleanup and file system maintenance

After active use of the memory card and transferring large amounts of data, it is recommended to maintain the file system, this will help to avoid read errors and speed up access to files. Periodically check the card for errors through the storage settings.

Also, you should regularly clean the cache of applications that actively work with media files, such as galleries or video players. Go to the application settings, select Storage and click Clear Cache. This will not delete your files, but will remove temporary thumbnails and data that may have been copied to internal memory.

If you notice that the phone has begun to open a photo from the card for a long time or the video slows down when playing, try to remove the card, wipe the contacts and paste again, or reboot the device. In critical situations, you may need to fully format the map on the computer with a check for broken sectors.
