Owners of Xiaomi, Redmi and POCO smartphones often face a lack of internal storage, especially given the high resolution of modern cameras.Moving photos to an external drive is the most effective way to free up valuable space for the system to work and install applications. This procedure does not require complex technical knowledge, but has its own features in the shells of MIUI and the new HyperOS.
It is important to understand that standard Android settings do not always allow you to automatically save all photos at once. SD-System security constraints often force users to use the built-in memory for the main data stream, but there are proven methods to circumvent these restrictions and manually transfer data.
In this article, we will discuss in detail the algorithms of actions that will help you move the archives of images without loss of quality. We will consider both the regular tools of the file manager and the specific camera settings that are relevant for current models of smartphones of the Chinese manufacturer.
Preparation of memory card and compatibility check
Before you start manipulating files, you need to make sure that the drive itself works correctly. The file system must be formatted correctly so that the smartphone can write large data to it. Usually Xiaomi devices offer to format the card immediately after installation, and you should not refuse this.
If the card has been used in other devices before, it is recommended to complete formatting through the phone menu, this will eliminate possible file structure errors and ensure maximum write speed. For modern cameras with a high bitrate video, it is better to use U3 or V30 cards.
β οΈ Note: Formatting a memory card will completely destroy all the data on it. Be sure to back up important files on your computer before starting the procedure.
It is also worth checking the physical condition of the card and smartphone tray contacts. Dust or oxidation can cause recording interruptions, which is critical when shooting in RAW or 4K video. Make sure the card is inserted before the characteristic click.
Automatic Configure Save in the Camera App
The first and most obvious step is to try to switch the standard camera app to an external drive, which is available in basic settings on most Redmi and POCO models, so you have to open the app, click three bars in the corner, and select a gear settings.
In the menu that opens, you should look for an item associated with the storage. It can be called "Save on the storage device". SD-The map, or the way to save, activating this slider will redirect all future images and videos directly to external memory.
- πΈ Open the Camera app and go to the settings menu.
- πΎ Find the "Storage" or "Saving" sectionΒ».
- β Activate the switch "Save to" SD-mapΒ».
- π Take a test shot and check its location.
It is worth noting that some MIUI updates for flagship models may not have this option, because internal UFS memory is much faster than microSD cards, and the manufacturer is keen to avoid lubricating frames during serial shooting.
Manual transfer of files through the Explorer
If automatic saving is not available or you need to move an existing archive, you will have to use a file manager. Xiaomi smartphones preinstalled its own βConductorβ, which has convenient access to the root structure.
To start, open the Explorer app and go to Images or Camera, which usually stores all the images you take, select the files you need with a long press, or use the Select All feature on the menu.
After selecting, click the Move button (not Copy to avoid duplicate data and space twice). The system will prompt you to select the target directory. You need to go to the section Β«SD-map and create or select a folder, for example, DCIM/Camera_Backup.
βοΈ Transfer algorithm
The process of moving a large number of files can take time. It is not recommended to fold the application or lock the screen to avoid interruption of the operation.
Use of the application Files from Google
An alternative and often more stable tool is the Files by Google system application, which is often bundled or available in the Play Market, and has a more advanced interface for working with two repositories at once.
Unlike a standard conductor, it's easier to visually separate the internal memory from the map. Open the Overview tab, select Internal Storage, and find the DCIM folder, and inside it is the Camera folder that contains your pictures.
Select the media files you want, click on the three dots in the top corner, and select Move to.. In the list of available places, select the three dots in the top corner. SD-The advantage of this method is that it provides a more informative display of the progress bar and speed of copying.
β οΈ Note: When moving system folders or files with access rights (DRM) You can make mistakes. You can only transfer user-generated content: photos, videos, documents.
The app also knows how to find duplicate files, which is useful after transferring data. You can run a cleanup to make sure that the originals in the internal memory are actually deleted.
Speed Comparison: Internal Memory vs. SD
Users often wonder if it's worth storing a photo on a map at all, given the difference in performance, and read-write speed is a key parameter that affects gallery speed and the ability to capture serial footage.
Modern smartphonesβ internal memory is UFS 2.1, 3.1, or even 4.0, which provides a tremendous data exchange rate, and even expensive memory cards are far inferior in this indicator, which can lead to delays when viewing heavy albums.
| Parameter | Internal Memory (UFS) | SD Card (Class 10) | SD Card (UHS-I) |
|---|---|---|---|
| Recording speed | up to 1500 MB/s | up to 30MB/s | up to 90MB/s |
| Reading speed | up to 2,000 MB/s | up to 80 MB/s | up to 170 MB/s |
| Launching applications | Instant. | Slowly. | Medium. |
| Reliability | Tall. | Medium | Tall. |
And you can see from the table that it's better to use the internal storage for operational work, and leave the memory card for archiving. SD-The map is ideal for rarely used shots that donβt need to be viewed or edited often.
Why does the gallery take so long to load photos from the map?
The answer: Why the phone can't see the photo
Sometimes, when you move files, they disappear from the standard gallery, because the Android media scanner hasn't updated the database, or the file has been moved to a hidden system folder, and in such cases, it helps to reboot the device.
The problem can also be in file format. If you've been transferring HEIC or RAW images from other devices, a standard Xiaomi viewer may not display them without installing codecs. Check the file extension through properties.
- π Reboot your smartphone to update your media index.
- π Check the Hidden or Recycle Bin folder in the Gallery app.
- π Make sure the file does not get into the.thumbnails folder.
If files are visible in the explorer but not in the gallery, try clearing the Gallery app cache through the application settings, which will force you to rescan the media files on both drives.

To speed up scanning of new photos on the memory card, after transfer, connect the phone to the charger and leave the screen on for 10-15 minutes.
Storage and cloud services
It is not enough to simply transfer files, you need to organize them correctly. On the memory card, create folders by year or event (for example, create folders by year or event, 2026_Vacation, 2026_Family). This will speed up search and navigation, especially if there are thousands of files.
Memory cards are more likely to break suddenly than internal smartphone memory, and backing up to cloud services like Google Photos or Xiaomi Cloud remains a mandatory rule of digital hygiene.
Use the memory card as an intermediate buffer, throw it every six months onto your computer or cloud, and clear it for new shoots, which will balance the free space on your phone with data security.
β οΈ Note: Do not remove the memory card while recording a video or saving a photo. This is guaranteed to damage the file and possibly lose data on the entire map.

The optimal strategy is to shoot on internal memory for speed, and once a week to transfer the filmed to the camera. SD-map, make room for new staff.
