Owners of brand smartphones Xiaomi Redmi often face a lack of built-in storage. High-resolution photos, videos, and caches of popular apps can quickly eat up your free space. A logical question arises: how to transfer phone memory to a memory card to free up internal space without losing data? In the ecosystem, and in particular in the shell, this process has its own nuances that distinguish it from standard procedures. Android, and in particular in the shell MIUI, this process has its own nuances that distinguish it from standard procedures.
Unlike older versions of the operating system, modern firmware limits the direct transfer of system files. However, there are several effective methods for organizing data storage. You can transfer the media manually, change the default save settings, or even make SD card part of the system partition. The choice of a specific method depends on your firmware version and device model.
Before taking active steps, you need to understand the types of memory cards and their compatibility with your gadget. Choosing the wrong media can lead to loss of smartphone speed or damage to files. Below we will look in detail at all the available memory expansion options for devices in the line Redmi.
Preparing a memory card and checking compatibility
The first step is the physical installation of the drive. Redmi smartphones usually support the microSDformat, but it is important to consider the maximum volume that your processor can recognize. Most modern models support cards up to 256 GB or even 512 GB, but older devices may be limited to 32 GB.
⚠️ Attention: Before installation, make sure that the memory card does not have physical damage to the contacts. Using low-quality media can lead to a malfunction of the smartphone's power controller.
After installing the card in the slot, the system will prompt you to configure it. Here you have two options: use as portable media or format as internal memory. The first option makes it easy to remove the card and transfer data to other devices, the second makes the card an integral part of the system, encrypting the data. The second method requires a high-speed card, preferably class UHS-I U3 or higher.
It is important to understand that when formatted for internal memory, all data on the card will be permanently deleted. Therefore, first copy important files to your computer or cloud storage. If your card was previously used in another device, it is recommended to perform a full format through the phone settings for correct operation of the file system.
For stable system operation, choose memory cards from trusted brands such as Samsung, SanDisk or Kingston. Cheap analogues often have overpriced specifications and low recording speeds.
Manually transferring photos and videos through Explorer
The safest and most common method of freeing up space is manually transferring media files. In the shell MIUI for this purpose, the “Explorer” application is preinstalled. It allows you to easily manage your file structure and move large amounts of data without using third-party software.
The transfer process is intuitive. You need to go to the application, select a file category (for example, “Images” or “Videos”), highlight the desired elements and select the move option. The system will prompt you to specify the destination directory on the memory card. It is recommended to create a separate folder, for example DCIM_Migratedto avoid mixing up old and new files.
- 📂 Open the Explorer application on the main screen.
- 🖼️ Go to the “Images” or “Videos” section and press the button “Select.”
- 📤 Click on the menu (three dots) and select “Move”, then select the memory card.
It is worth noting that after transferring files, the gallery may take time to update the index. Sometimes new folders do not appear immediately. In this case, you can use the “Refresh” function in the Gallery application itself or simply restart the device. This action will force the media scanner to scan the drive again.
☑️ Preparing to transfer files
Setting the default data saving to the SD card
To avoid constant manual transfer, it is advisable to change the saving settings for cameras and instant messengers. In the settings of the Camera application on Redmi, there is an item that allows you to set the path for saving pictures. Activating this feature automatically sends all new photos and videos to the external drive.
Open the camera app, tap the menu icon (three bars) in the top corner and go to settings. Find the "Save to SD card" switch and turn it on. Now the internal memory will be used only for system needs and application cache, and heavy media files will be immediately written to external media.
| Application | Data type | Possibility of transfer | Recommendation |
|---|---|---|---|
| Camera | Photo and Video | Full (automatic) | Enable in camera settings |
| Telegram | Media cache | Partial (cache setting) | Use built-in cleaning |
| YouTube | Offline video | Depends on version | Check in download settings |
| Voice recorder | Audio recordings | Full | Select SD card in settings |
Similar settings exist in other applications. For example, in a voice recorder or some video editors, the save path can be changed in the settings section. However, popular instant messengers, such as WhatsApp or Telegram, often store caches in the internal memory by default, and transferring them requires additional steps within the applications themselves.
Transferring applications to a memory card (Android 6+)
The issue of transferring installed applications is one of the most difficult in the modern ecosystem Android. Since version 6.0, Google has implemented the feature Adoptable Storagebut manufacturers, including Xiaomi, often disable it at the firmware level to ensure system stability. However, it is still possible to partially transfer applications.
Go to Settings → Applications → All applications. Select the desired app. If the developer has allowed the transfer, you will see a "Move to SD Card" button. If the button is inactive or missing, it means that the application is tightly bound to the system partition. This often applies to banking clients and system services.
⚠️ Attention: Even if the transfer is successful, some application data (cache and important settings) will remain in the internal memory. It is not possible to completely free up space by transferring one app.
For advanced users, it is possible to enable full support for transferring via USB debugging mode and commands ADB, but this requires a connection to a computer and carries the risk of unstable operation of the smartphone. The standard method through the settings is the most secure, although it has limitations.
How to enable transfer of applications via ADB?
To do this, you need to activate developer mode, connect the phone to the PC and enter the command: adb shell pm set-install-location 2. This will force installation priority to an external card, but may slow down heavy applications.
Using the card as internal memory (Formatting)
The most radical method is to format the memory card as internal storage. In this case, the system encrypts the media and combines its volume with the built-in memory. For the user, it looks like a single space, and applications can be installed directly on the card without manual transfer.
To activate this feature, go to Settings → Storage. Select your SD card, open the menu and click Format. In the window that appears, select the “Internal memory” option. The system will warn you about data loss and low speed compared to the native drive. Confirm the action and wait for the process to complete.
After the operation is completed, the phone will treat the card as a system drive. It is strictly forbidden to remove it without first “unmounting” it in the settings - this will lead to errors in the operation of applications and possible download failure. It is also worth considering that when you reset the phone to factory settings, the data on such a card will also be deleted.
Using the card as internal memory is convenient for budget models with a small amount of built-in storage, but requires a high-speed U3 class card.
Possible problems and ways to solve them
During operation, users may encounter a number of technical difficulties. One of the common problems is a card reading error message or files suddenly disappearing. This is often due to incorrect removal of the media or the use of a file system that is not supported by the current version of the kernel Android.
If the phone no longer sees the card, try rebooting the device. If this doesn't help, remove the card, gently wipe the contacts with a soft eraser, and reinsert it. If the problem persists, you may need to reformat it again. Remember that frequent formatting shortens the life of flash memory.
- 🔄 Reboot your smartphone to update the file system.
- 💾 Check the card on another device (PC or another phone).
- ⚙️ Perform formatting through the phone settings (not through PC).
Another common situation is the slowdown of the interface. This happens if you have installed heavy applications on a slow memory card. The internal memory of smartphones is much faster than most microSD. Therefore, it is better to leave system applications and games with heavy graphics on the built-in storage.
⚠️ Attention: The MIUI interface and settings may vary slightly depending on the firmware version (Global, China, Russia). If you do not find the described menu item, check for system updates.
Frequently asked questions (FAQ)
Is it possible to transfer all applications to a memory card on Redmi?
It is impossible to completely transfer all applications. System apps and some critical services must remain in the internal memory for stable operation of the device. In addition, many application developers block the ability to transfer to external media.
Why did they disappear from the Gallery after transferring photos?
Most likely, the .nomedia file ended up in the folder with photos, or the media scanner has not yet updated the database. Try restarting your phone or checking the folder through Explorer. Also make sure that displaying files from the SD card is enabled in the Gallery settings.
Is it safe to use the card as internal memory?
It is safe from the point of view of data integrity if the card is of high quality. However, your phone's performance may be slower because memory cards are typically slower than built-in flash memory. You also lose the opportunity to quickly transfer data to another phone without formatting.
What class of memory card is needed for Redmi?
For comfortable work and recording video in high definition, it is recommended to use speed class cards U3 (UHS Speed Class 3) and standard V30. This will ensure sufficient speed for writing and reading data.
What to do if the phone does not see the memory card?
Try clearing the card contacts, rebooting the device, or formatting the card on your computer to the exFAT or FAT32 file system. If all else fails, the card may be faulty or incompatible with your smartphone model.
