Xiaomi smartphone owners often face a lack of space, especially if they actively shoot 4K videos or take high-resolution pictures. The device’s built-in memory fills up quickly, which leads to a slowdown and inability to install new applications. The solution is the use of an external microSD card, which allows you to significantly expand storage for multimedia.
The process of transferring data to a memory card in the MIUI shell has its own features that distinguish it from standard Android. It is important not only to copy files, but also to properly configure the system so that the camera and voice recorder save new records by default to an external drive, in this guide we will discuss all the current ways of solving the problem.
We’ll look at the file manager tools, the camera settings, and the capabilities of the computer as a means to mass-transfer archives, and we’ll also look at the important nuances of formatting and data security so that your photos and videos don’t get lost in the optimization process.
Preparation of memory card and smartphone for work
Before you start copying files, you need to make sure that the memory card is correctly installed and recognized by the MIUI operating system. Put the card in the tray, observing the polarity of the contacts, and wait for the notification system. If the notification does not appear, check the status of contacts or try to restart the device.
Modern Xiaomi smartphones require a card formatting in a FAT32 or exFAT file system to work smoothly. If the card is new or used on another device, the system may suggest formatting it immediately after detection, a mandatory procedure to create the correct folder structure.
⚠️ Note: Formatting completely removes all data from the memory card. If it has important information on it, pre-copy it to a computer or cloud storage.
After successful formatting, a new partition will appear in the File Manager, usually designated as SD-Now the drive is ready to write data, and you can move to transfer existing photos and videos.
Using Built-in Explorer to Transfer Files
The fastest and most reliable way to move existing photos and videos is to use the standard File Manager app preinstalled in every Xiaomi smartphone, which does not require an internet connection or third-party software installation.
To start, open the app and go to the internal memory section. Find the DCIM folder, which is the default storage of your camera images and videos. Inside this folder, you're interested in the Camera subfolder, where all your media files are.
☑️ Pre-transfer check
Select the necessary files with a long press or use the Select Everything in the Control menu. Click Copy or Move, then go to the root SD-Create a folder with a clear name, for example, Photo_Backup. Insert files into a new directory.
Using the Move function will free up space in the internal memory immediately, while Copy will create duplicates, and the source files will have to be manually deleted. Be careful when choosing the action so as not to overflow the memory card.
Setup the camera to save to an SD card
To save new images and videos automatically to an external drive without taking up internal space, you need to change the settings of the Camera application, which will save you from having to constantly transfer files manually in the future.
Open the Camera app and click on the menu icon (three bars) in the top right corner. Select Settings and scroll through the list to the save-related section. Find the Save to the Save to the Save to the Settings button. SD-map and activate it.

If the switch is inactive or missing, your version may be MIUI does not support direct conservation RAW-file 8K External storage due to recording speed limits.
Once this option is enabled, all new media files will be placed in the DCIM/Camera folder on the external map. Please note that some shooting modes, such as 8K Video or high-resolution slow motion shooting, may still require internal memory to ensure stable recording speeds.
⚠️ Note: Use of slow memory cards (class below 10) to record video in 4K It can cause recording interruptions or artifacts appearing in the video.
Working with Multimedia through Computer
If you need to transfer a huge archive of photos or high-quality videos, the most convenient way to use a computer is to quickly copy gigabytes of data without the risk of discharge of the smartphone or transmission errors over the wireless network.
Connect your smartphone to your PC with USB-The phone will be asked for mode of use. USB — Select File Transfer (MTP). The computer will define the device as an external drive.
In the My Computer window, open the Xiaomi device, then go to internal memory and find the folder. DCIM. Select the files you need, copy them (Ctrl)+C and insert (Ctrl)+V) in the corresponding folder on SD-a card that will appear as a separate disk or partition in a list of devices.
Once you have finished copying, make sure to safely extract the device from Windows or macOS. This ensures that all write buffers are cleaned and files are not damaged.
Comparison of data transfer methods
The choice of transfer method depends on your goals: whether you just need to make room right now or you want to set up automatic operation for the future, each method has its advantages and limitations.
Below is a table that helps you compare the main characteristics of different memory management approaches on Xiaomi devices.
| Method | Speed. | Convenience | Risks. |
|---|---|---|---|
| Conductor (Internal) | Tall. | High. | Low. |
| USB Cable + PC | Maximum | Average. | Low. |
| Cloud services | Low. | High. | Network dependency |
| Cliner applications | Medium | Low. | Advertising, mistakes |
For regular maintenance, the best combination is automatic saving of new photos on SD and periodic manual sorting of old archives through a computer.
Possible problems and solutions
During the process of transferring files, users may experience write errors or file disappearances, often due to damage to the card's file system or physical defects in the drive itself.
If your smartphone stops seeing the card or files aren’t being copied, try removing the microSD, erasing the contacts, and pasting back in. Re-formatting through the Settings menu → About Phone → Storage will also help.
What if files are copied but not opened?
Another common problem is the message “File is too big” that occurs when you try to burn more than 4 GB of video to a card with the FAT32 file system, in which case you need to format the card in exFAT format, which supports large files.
⚠️ Note: Do not remove the memory card during the process of writing or copying files, this can lead to irreversible data loss and damage to the partition table.
