Owners of smartphones Xiaomi, Redmi and POCO Often face a lack of internal storage, especially when shooting in high resolution. SD-The card becomes the only way to free up precious gigabytes without removing important applications. MIUI HyperOS offers flexible tools for managing the file system, allowing you to manually or automatically move content.
However, the process is not always smooth due to the security limitations of Android and the peculiarities of the Xiaomi gallery. Misplacement can lead to photos disappearing from previews or no longer appearing in albums. In this guide, we will discuss in detail all ways of migrating data, from built-in tools to advanced methods through file managers.
It's important to understand that your smartphone's speed is directly dependent on the system partition being full, and that freeing up internal memory not only allows you to load more content, but also speeds up the interface. Here are some proven action algorithms that ensure your data is safe.
Preparation SD-maps and compatibility checks
Before moving files, you need to make sure that the memory card is properly installed and formatted in the file system supported by Android. Most modern Xiaomi devices work with microSDHC and microSDXC cards up to 1 TB and higher. If you just inserted a new card, the system will automatically prompt you to configure it - select the option "Use as a portable storage" if you plan to transfer only photos and videos.
Pay attention to your card speed class. You need high recording speeds to record 4K video or take photos in series, otherwise you may experience save errors or friezes at the time of shooting. You can check the current status and amount of free space in the device settings.
- 📱 Go to Settings. → The phone. → Storage for viewing total memory.
- 💾 Make sure that SD-The card is displayed in the list and has the status "Connected».
- ⚙️ If necessary, format the card by selecting the exFAT file system or FAT32.
⚠️ Note: Formatting a memory card completely deletes all data on it. Before starting the procedure, be sure to copy important files from the card to your computer or to cloud storage if something is already written on it.
Once installed and formatted successfully, the system will create the necessary hidden folders for system files, and the storage is now ready to receive your photos and videos from the phone’s internal memory.
Transfer through a standard file explorer
The most reliable and versatile way to move data is through the built-in File Manager app, which gives you complete control over the process and allows you to select specific folders or individual files to transfer. Unlike the automatic camera settings, the manual method ensures that you move exactly what you need.
Open the Explorer app on your device. You'll need to go to the root directory of the internal storage. Usually, the photos are on the way. DCIM/Camera, And the screenshots are in the folder. Pictures/Screenshots. Select the desired files in a long tap or select the entire folder through the “Select All” menu».
☑️ Algorithm of file transfer
After selecting, click on the Copy or Move button in the bottom menu bar. The system will create a clipboard «SD-map" or in the navigation menu, select your map. Create a new folder with a clear name, for example, Photos_Archive, Or use the existing directory structure.
Finish the operation by pressing the "Insert" button. The speed of copying depends on the volume of data and the speed class of the card. Do not interrupt the process or turn off the device screen while writing large files to avoid data corruption.
| Type of data | Location in internal memory | Recommended seat on SD |
|---|---|---|
| Photo from the camera | /DCIM/Camera | /DCIM/Camera (on SD) |
| Video from the camera | /DCIM/Camera | /DCIM/Camera (on SD) |
| Screenshots | /Pictures/Screenshots | /Pictures/Screenshots (on SD) |
| Downloads (Downloads) | /Download | /Download (on SD) |
Automatic recording of photos and videos on the map
To avoid wasting time on manual transfers in the future, you can set up automatic saving of new images immediately to the external drive, a feature available in the standard Xiaomi Camera app, but its location may vary depending on the version of MIUI or HyperOS.
Open the Camera app and click on the three horizontal bars in the upper right to open the settings menu. scroll down to the settings section. SD-Map" and activate the switch. From now on, all new media files will be written by default to external storage.
💡
If you are shooting a high-resolution video (4K 60fps), The system may temporarily ignore the setting SD-card and save the file to internal memory to ensure stable recording if card speed is insufficient.
Note that when the video accelerator function is enabled or when certain shooting modes are used (for example, Cinema Effect or slow motion), files can still be stored inside, this is due to memory card bandwidth limitations that the system algorithms take into account to prevent frame loss.
It’s also worth noting that when you reconnect the card or retrieve it, the gallery may take time to index new files.If you see empty albums after you turn on this feature, just restart the device.
Use of the Files app from Google
Many Xiaomi smartphones have Files by Google preinstalled, which offers a more modern and user-friendly memory management interface than a standard conductor, can analyze space and offer cleanup, and has easy access to both storages in one window.
Launch the app and go to the Overview tab. In the Devices section, you'll see two options: Internal Storage and yours. SD-map (often referred to as «SD-Open the internal storage, find the folder. DCIM And select the files you want.
- 📂 Click on three dots in the corner of the screen and select “Select All” or select specific files.
- ✂️ In the menu that appears, select “Move to...».
- 🗂️ In the list of devices, specify yours SD-map and target folder.
The advantage of this method is that you can visualize the process: you can see the progress bar and the speed of the copy in real time, and the application automatically checks for duplicates and can suggest that you delete the originals after successful copying, which saves time.
⚠️ Note: When using third-party file managers, make sure you give the app permission to access all files (MANAGE_EXTERNAL_STORAGE) You will not be able to see the contents of some system folders or move them.
Set up multimedia applications (WhatsApp, Telegram)
Memory deprivation is often not just a problem with camera photos, but also with messaging. Apps like WhatsApp and Telegram default to store all images and videos they receive in internal memory. Fortunately, you can change the way you save them in the settings of the apps themselves.
On WhatsApp, go to Settings → Chats. If your version supports changing storage, there will be a "Use" item. SD-However, in the latest versions of Android, direct path change is often blocked, in which case it is more effective to use the Clear Data function inside the application, saving important files beforehand.
For Telegram, the situation is simpler: open Settings → Data and memory → The path to the files. You can clearly point the folder to the SD-This will significantly reduce the system partition, since Telegram cache can take up tens of gigabytes.
Regularly cleaning these folders or transferring them to an external medium is the key to stable smartphone operation. Remember that deleting files from chat messengers only deletes them from the interlocutor if you use the “delete for all” function, so archiving to a memory card is the best way to save the history of correspondence.
Possible problems and ways to solve them
Users may encounter various errors during data transfer, most often related to the card file system or Android shell software failures. If you see a message "File is corrupt" or "Can't move", first check the integrity of the memory card on your computer.
Another common problem is the disappearance of thumbnails (previews) in the gallery after the transfer, which is because the Android media scanner does not immediately update the database, in which case it helps to reboot the device or clear the cache of the Gallery and Mediaservice application through the application settings.
What to do if the card is not readable?
Also worth mentioning is the “slow” way the gallery works when viewing a photo on a map, which is normal for low-speed cards (Class 4 or 6). For comfortable viewing of thousands of photos, it is recommended to use UHS-I or UHS-II cards.
If neither method works, it may be physical damage to the slot or the card itself. Try using another memory card for diagnostics. In rare cases, resetting network and Bluetooth settings helps, as they can conflict with the memory controller.

Regular backup to external media is the best protection against data loss in case of system failures or smartphone breakdown.
