Owners of Xiaomi Redmi and Poco smartphones often face a lack of built-in storage, especially if the device has a storage capacity of 64 or 128 GB. High-quality pictures and videos in 4K quickly fill the free space, forcing the system to work slower or blocking the ability to install new applications. The solution is the use of a microSD memory card, which can transfer media files to free up the bulk.
The process of moving data in the MIUI shell or the new HyperOS is implemented with enough flexibility, allowing the user to choose the source and recipient of files. However, many people are unaware of the hidden camera settings that allow you to save new images immediately to an external medium, bypassing internal memory. In this article, we will discuss in detail all available methods, from automatic settings to manual transfer through the file manager.
It's important to understand that the right storage not only saves space, but also increases the security of your personal photos. In the event of a system failure or the need to flash your smartphone, the files on the memory card will remain intact. Let's consider how to properly configure your Redmi to work with an external drive.
Preparation of memory card and compatibility check
Before you start transferring photos, you need to make sure that your memory card is correctly defined by the system and formatted in the appropriate file format. Xiaomi smartphones usually support cards up to 512 GB and even 1 TB, but for stable operation it is recommended to use carriers of the UHS-I or UHS-II speed class. If the card is new or previously used in other devices, it is better to format it directly in the phone.
To do this, insert the card into the slot (combined with a tray). SIM-You can either have a card or a card, depending on the model, and wait for the notification, and the system will suggest you set up the drive. Choose the use case as “Portable Storage” if you plan to move the card to other devices, or “Internal Storage” to expand the system memory (the latter will encrypt the card and make it unreadable on other phones without resetting).
⚠️ Note: Formatting a memory card completely removes all data on it. If the card already has important files, pre-copy them to your computer or cloud storage.
Check the status of the card in the settings menu. Go to Settings → About Phone → Storage (or just Settings → Memory). This shows the total volume, occupied space and read/write speed. Make sure the card file system is FAT32 or exFAT, as the NTFS format may not be supported without third-party utilities.
💡
Use memory cards only from proven brands (SanDisk, Samsung, Kingston). Cheap counterparts can have real capacity much less than claimed, resulting in loss of photos and recording errors.
Set up automatic photo saving on SD-map
The most effective way to avoid internal memory overflow is to set up the standard Camera app so that it defaults to saving all new images and videos to an external medium. In the MIUI shell, this option is often hidden in the additional settings of the camera app itself, rather than in the general settings of the system.
Open the Camera app and click on the three horizontal bars in the top right corner of the screen. In the menu that appears, select Settings. Scroll down to the data retention section. Find the Save to SD-You can use the card or save it and activate it, and then all the new photos will be marked by the system as files on an external drive.
- 📸 Open the Camera app on the home screen.
- ⚙️ Click on the menu (three bars) and select Settings».
- 💾 Find the item "Save in" SD-map" and turn on the switchboard.
- ✅ Take a test shot and check its properties in the gallery.
It’s worth noting that some older versions of the shell or specific shooting modes (such as slow-motion video or bokeh portrait mode) may ignore this setting and store data in internal memory, due to the requirements for write speeds that cheap memory cards may not provide, in which case the system will automatically switch to internal storage to prevent frame loss.
Manual transfer of photos through the app “Conductor”
If you can’t automatically set up or need to move your existing photo archives, the best tool is the built-in file manager, which is called Explorer (or File Manager) on Xiaomi smartphones and has advanced functionality to work with the file system as if it were on a computer.
To start, open the Explorer app. On the home screen, you'll see file categories. Click on the Images icon or go to file viewing mode (Folders or Review tab). Find the DCIM → Camera folder, which is where the default images are stored. Highlight the desired photos with a long press, then select the rest or use the "Select All" button.
Once you have selected files, click the "More" button (three dots) at the bottom of the screen and select "Move" or "Copy" action. The difference between the two is significant: "Copy" will create a duplicate of files on the memory card, leaving the originals in internal memory, and "Move" will move the files, freeing up space. To save space, you'd better use the movement.
☑️ Algorithm of file transfer
Select your target directory as yours. SD-map (usually indicated as SD It is recommended to create a separate folder there, for example, Photos_Archive, When you're done, check for files in the new folder and make sure they open correctly.
Using Cloud Services as an Alternative
Not always a physical memory card is the best solution, especially if you change devices frequently or fear data loss due to a microSD breakdown. Cloud storage like Google Photos, Yandex.Disk or Mi Cloud offer automatic synchronization, which can be a great alternative or addition to local storage.
Set up sync in Google Photos takes a couple of minutes. Open the app, click on your profile avatar and select Photo Settings → Autoload and Sync. Here you can select the download quality (“High quality” without space limit or “Original” with the consumption of Google One quota) and specify whether to download photos only via Wi-Fi or also via mobile Internet.
| Parameter | SD-map | Cloud storage | Internal memory. |
|---|---|---|---|
| Speed of access | High (locally) | Depends on the Internet. | Maximum |
| Risk of loss | Medium (physical wear and tear) | Low (reservation) | High (when the phone breaks) |
| Cost | One-time purchase | Monthly subscription (often) | Included in the phone price |
| Availability | Only if you have a card. | From any device | Only on the phone. |
Using the cloud is especially important for Xiaomi owners, because the Mi Cloud ecosystem is deeply integrated into the system, which allows you not only to store photos, but also to back up contacts, notes and voice recorders. However, for large volumes of 4K video, 5 GB of free space may not be enough, and you will have to buy additional tariffs.
Errors Resolving When Working with a Memory Card
Despite the simplicity of the procedure, users often encounter errors when the phone "can't see" the card or refuses to write files to it. One common problem is format error. If the card is formatted in the NTFS file system (standard for Windows), Redmi's phone can see it, but can't write data. The solution is formatting in exFAT.
Another common situation - a message «SD-This may indicate logical errors in the file system, try connecting the card to your computer through a card reader and run error checking with Windows or use utilities like this. CHKDSK. If the error persists, it is possible that the card is physically faulty.
⚠️ Warning: If your phone is constantly giving out a card reading error, try gently erasing your microSD contacts with a pin or alcohol.
Also worth mentioning is the issue of access rights. In newer versions of Android (11, 12, 13, 14), applications have limited access to the file system. If Explorer can't move files, check in the App settings → Rights → Files and media content, is access allowed for the file manager. Sometimes cleaning the cache of the Media Scanner application in the Settings → Apps → All applications helps.
What to do if the photos are missing after the transfer?
Optimization of the gallery after the transfer
Once you've moved a photo onto a memory card, the smartphone gallery can behave strangely, like duplicate images, long openings of albums, or no thumbnails, because it takes time for the system to re-index media files, a background process that can be accelerated.
You can use a hidden menu to force the database to update your media files, or you can just reboot your device, and cleaning the cache of the Gallery and Media Scanner app also helps. Go to Settings → Apps → All Apps → Gallery → Memory and click Clear Cache. Don't confuse Clear Data with Clear Data, otherwise your album display settings may be confused.
If you use third-party galleries (like Google Photos or AGallery), make sure that their settings enable scanning of external drives. SD-Map to save traffic or battery. Google Photos, you need to go to the settings and select "Device folders" to add the display of folders from the memory card.
💡
Regular cleaning of the media scanner cache and the use of quality UHS-I memory cards extends the life of the smartphone and prevents data loss.
