Owners of modern smartphones Xiaomi, Redmi and POCO often face a lack of free space in internal memory, especially if the camera of the device shoots in high resolution. Overcrowded drive leads to slowdown of the system, inability to install new applications and failures when creating new images. The only effective solution in this situation is to transfer media files to an external drive, which frees up valuable gigabytes for the operating system.
The process of moving images does not require a computer or special programming skills, since all the necessary tools are already built into the MIUI or HyperOS shell. You will only need an installed microSD memory card that must be formatted correctly and defined by the system. In this article, we will discuss in detail all available methods of transferring photos, from standard file manager tools to using cloud services.
The right file structure on the external media will allow you to keep access to photos even if your phone is reset or broken, and it also makes it easier to transfer data to the new device, because it's easy to remove the card and paste it into another smartphone. Let's look at the preparatory steps and the main ways to free up internal memory.
Preparation of memory card and compatibility check
Before you start copying files, you need to make sure that your microSD card is properly installed and recognized by the Android operating system.Put the card into the appropriate slot of the SIM tray, observing the correct orientation of the contacts, and wait for the notification system to connect the new drive. If there is no notification, go to the settings menu and select About phone, then click Storage to check if the volume of the external card is displayed there.
For stable work with high-resolution photos, it is recommended to use cards with a write speed not lower than UHS-I or V30. Slow cards can cause delays when shooting in serial shooting or when recording video in 4K, as well as long display preview images in the gallery. Formatting the map is best done by means of the smartphone itself, as this ensures the use of the correct file system, usually exFAT or FAT32.
⚠️ Note: Formatting a memory card completely removes all the data on it. If there are already important files on the card, pre-copy them to your computer or cloud storage.
Once formatted successfully, the system will suggest using the card as a portable storage device or as part of internal memory. To transfer photos and then use the card in other devices (cameras, card readers), choose Portable Storage, which will allow you to remove the card at any time and connect it to the PC without having to re-authorize or convert files.
💡
Use memory cards up to 512 GB for maximum compatibility with Xiaomi mid- and budget smartphones, as large volumes can run unstablely.
Use of built-in conductor for photo transfer
The most reliable and quick way to move photos is to use the standard Explorer app, which is preinstalled on all Xiaomi devices.This method does not require an Internet connection and allows you to control every file you move. Open the Explorer app on your desktop or in the Tools folder, then go to the Images or Internal Drive section.
For mass transfer of photos, perform the following actions:
- 📁 Press and hold your finger in one of the photos to activate the highlight mode.
- 📁 Use the “Select All” button in the top menu or select the folders you need manually.
- 📁 Click on the three dots in the corner of the screen or the “More” button and select the “Move” action».
- 📁 In the navigation window that opens, select «SD-Map and create or select the target folder.
Using the Move feature is preferable to Copy, as it allows you to immediately free up space in internal memory, rather than creating duplicate files. The process can take some time depending on the number and weight of photos, during which it is not recommended to run heavy applications or switch between tasks.
☑️ Transfer checklist
If you are transferring a very large amount of data (for example, more data) 10 000 It is advisable to break the process into several stages by folder or year, this will reduce the load on the memory controller and minimize the risk of writing errors that can lead to file damage. 30-40% before the start of a large-scale operation.
Set up automatic photo saving on SD-map
To avoid wasting time manually transferring images in the future, you can set up your smartphone camera so that new images are immediately saved to an external memory card, a feature available in Xiaomi’s standard Camera app, which automates the process, eliminating the need to constantly monitor the filling of internal memory.
To activate this feature, open the Camera app and click on the menu icon as three horizontal bars in the upper right corner. In the list that opens, find Settings (the gear icon), scroll down to the Save section, and activate the Save on switch. SD-After that, all new photos and videos will be recorded by default in an external drive.
| Parameter | Internal memory. | SD-map |
|---|---|---|
| Recording speed | High (UFS 2.1/3.1) | Depends on the class of the card. |
| Volume | Limited by the phone model | Up to 1 TB (expandable) |
| Risk of data loss | Low (when the phone breaks) | Medium (physical wear and tear) |
| Speed of access | Instant. | Could be a delay. |
It is important to note that while maintaining SD-The speed of the serial shooting may decrease if the card is used with a low write rate. RAW delays between frames can become more noticeable, so for professional shooting of dynamic scenes, it is better to temporarily switch to internal memory.

Transfer of photos through the Gallery app
The MIUI Gallery app provides a user-friendly interface for managing media files, allowing you to move entire albums or individual images without going to the file system, a method that is especially convenient for users who are used to sorting photos by event or date directly in the visual interface.
Open the Gallery app and go to the Albums tab. Select the album you want to move in full or open a specific photo. Click on the three dots in the upper right corner (or the "More" button in the bottom panel), select "Move to another album" or "Copy." In the navigation window that appears, select your SD-map and specify the target folder.
The advantage of using a gallery is that you see thumbnails of images and can visually evaluate the content before transferring. However, if you decide to move system albums (such as screenshots or downloads), the system can request additional permissions or warn about the possible loss of functionality of some applications.
⚠️ Note: When moving photos through the Gallery, make sure you don’t move system files that are necessary for other apps like WhatsApp or Telegram to work so as not to disrupt their work.
Once moved, files may disappear from the recently added tape on the gallery's home screen, as this section often indexes only internal memory. To find displaced photos, use the Albums tab and scroll down to the Other Albums section or «SD-map».
Working with big data and optimizing
When working with thousands of photos, it is important to understand the differences between copying and moving, and also to be able to optimize the process. If you plan to migrate the entire media library, it is recommended to do this in stages, sorting files by years or months, this will not only reduce the load on the smartphone processor, but also allow you to create a logical folder structure on the external media.
To speed up the process, you can use flight mode by disabling wireless interfaces that can interrupt an operation or consume system resources. Also close the background applications to maximize the available RAM for the file sharing buffer. If the process is stalled, do not rush to remove the memory card - wait for the operation to complete or force the Explorer application to close through the menu of running tasks.
Regular defragmentation is not required for the exFAT memory cards used in Android, but periodic error checking can be useful. To do this, connect the card to your computer through the card reader, right-click on the disk, select Properties → Service → Check. This will help identify and correct logical errors of the file system.
