Owners of Xiaomi, Redmi and Poco smartphones often face a lack of built-in storage, especially when shooting high-resolution video. Overflow memory not only blocks the ability to take new pictures, but also significantly slows down the entire MIUI or HyperOS operating system. The solution is the use of an external microSD card, which allows you to expand the available space without buying a new device.
The process of data transfer can vary depending on the firmware version and model of your gadget. In some cases, the system offers automatic saving of new images immediately to an external medium, in others it requires manual transfer of existing archives through the built-in conductor.
In this article, we will take a look at all the available methods for freeing up internal memory, how to set up a camera to automatically record on an SD, how to move old photos en masse, and what to do if the phone does not see the card, and following the instructions will allow you to effectively manage media files.
Preparation of memory card and smartphone for work
Before you start any file manipulation, you need to make sure that the memory card is properly installed and formatted. Formatting is a critical process that creates a file system that the phone understands. Please note that after this procedure, all data on the card will be deleted, so use only an empty card or pre-copy important files to your computer.
Insert a microSD into the smartphone tray using a clip or needle. Once the device is turned on, the system must automatically identify a new drive. If that doesn't happen, go to the settings menu. The path usually looks like: Settings β About Phone β Storage. Here you will see the status of the card and the available actions.
β οΈ Note: Do not remove the memory card during video recording or file transfer process, this can cause damage to the file system and loss of data that cannot be recovered by standard means.
For optimal work with photos and 4K video, it is recommended to use UHS-I or UHS-II speed cards with a volume of 64 GB. Older or slower cards may not cope with the flow of data when shooting, causing a recording interruption.

Buy memory cards only in trusted stores. There are many counterfeits in the electronics market that show full volume when connected to a PC, but lose data when recorded.
Setup of automatic photo saving in the camera
The most convenient way to avoid overflowing internal memory is to set the camera to automatically save new images immediately to the external media. In modern MIUI shells, this feature is often turned on by default when you detect a card, but requires checking. Open the Camera app and click on three bars in the upper right corner of the screen.
In the menu that opens, select Settings. Scroll down to the storage section. You need to find the Save to SD-- card or save priority. Activate the switch opposite this point.
- πΈ After the function is enabled, all new photos and videos will be recorded on an external drive.
- π Old photos will remain in the internal memory, they must be transferred separately.
- π₯ Serial and slow-motion modes sometimes ignore this setting due to recording speed requirements.
Itβs worth noting that some heavy shooting modes, such as 8K video or RAW-save Pro mode, may still require internal memory due to the high data streaming speed, in which case the system temporarily uses built-in storage.
Manually moving photos through the Explorer
If you need to migrate an existing photo archive, the best way to do this is to use a built-in file manager, which is called Explorer on Xiaomi smartphones, and has a yellow icon with a folder, which allows you to do mass operations with files without losing quality.
Open the app and go to the Internal Drive section, find the DCIM folder and the Camera folder inside, and that's where all the pictures taken with the standard camera are stored, select the photos you want with a long press, or select the option to Select everything from the menu.
βοΈ Algorithm for moving files
Once you've allocated files, click the Three Dots button and select Move. It's important not to confuse copying with copying if you want to vacate space. The system will tell you to choose destination. SD-map, create a new folder or select an existing one, such as Photos, and click Insert or OK.
What to do if the movement is suspended?
Use of the Gallery app for sorting
The MIUI Gallery app has an enhanced functionality that goes beyond just viewing, allowing you to not only view media, but also manage the location of media. Open the gallery, go to the Albums tab, and find the Camera album.
Press and hold your finger on one of the photos to go into highlight mode. You can select specific pictures or groups. After selecting, click on three dots in the corner of the screen. The menu may not have a direct "Move to SD" button, as the functionality depends on the Android version. However, the option to Create an album is often available.
Creating a new album inside the gallery does not physically move files, but only creates a virtual link. For real transfer, it is still better to use the method described in the previous section through Explorer, or specialized applications for managing files, such as Files by Google or Solid Explorer.
- π Gallery is convenient for preview before removal or transfer.
- ποΈ Removing photos from the gallery frees up space, but doesnβt change their location.
- π Cloud sync can duplicate files by taking up space twice.
Table: Comparison of data storage methods
The choice of storage method depends on your priorities: speed of access, volume or reliability. Below is a comparison of the main options for placing photos on Xiaomi devices.
| Parameter | Internal memory. | SD-map | Cloud storage |
|---|---|---|---|
| Read/write speed | High (UFS) | Medium/Low | Depends on the network. |
| Risk of data loss | Low. | Medium (physical wear and tear) | Low. |
| Access without the Internet | Yes. | Yes. | No (no cache) |
| Impact on the speed of the phone | Strong when filled | Minimum | Absent. |
As you can see from the table, internal memory such as UFS provides the highest speed of applications and cameras, so system files and frequently used programs are better left there.

The best strategy is to keep only current projects and photos in your internal memory for the last week, and archive the rest on your own. SD-map.
Frequent problems and their solution
Users may experience a situation where the phone stops seeing the memory card or refuses to write files to it. Often the reason lies in the file system. Android works best with the exFAT format for large-volume cards (over 32 GB). If your card is formatted in FAT32, the phone may not recognize files larger than 4 GB.
Another common problem is the error "SD-This may indicate a logical failure. Try to extract the card, paste it into your computer through a card reader and check for errors with Windows or macOS. Also helps re-formatting directly in the phone's settings menu: Settings β The phone. β Warehouse β SD-map β Format.
β οΈ Warning: If the phone keeps writing that the card is damaged, even after formatting, the card controller may have failed or the contacts in the smartphone tray oxidized.
In some cases, applications may not have permission to access an external drive. Go to Settings β Applications β All applications, find the desired application (such as Gallery or Explorer), go to Permissions and make sure that access to Files and Media is allowed.
