Xiaomi Redmi smartphone owners often face a lack of built-in space, especially when using the camera actively. High-resolution images and 4K video quickly fill gigabytes, forcing the system to warn of a critical memory level. The solution is the installation of a microSD card that allows you to expand storage without losing data and functionality of the device.
The process of transferring images is not always obvious, because in the MIUI or HyperOS shell, settings can be hidden or have specific names. In this article, we will discuss all methods in detail: from automatically recording new frames directly to an external medium to manually moving existing archives through the file manager, you will learn how to properly manage the folder structure and avoid common errors.
Using an external drive is not just a free-up of space, it's a way to protect your data. If something happens to your phone, the photos will remain intact on the removable map. SD-The map will make it easier to find and transfer them to other devices in the future.
Preparation of memory card and phone for work
Before you start transferring data, you need to make sure that the external drive is properly installed and formatted.Modern Xiaomi smartphones require that the card be formatted in the exFAT or FAT32 file system for proper operation.Put the card into the slot, wait for the system notifications and follow the on-screen prompts.
It is important to check the speed of writing the card, as slow drives can cause delays when shooting serial photos or recording high-resolution videos. If the card was used previously in another device, it is better to perform full formatting through the phone settings to avoid file system conflicts. This action will remove all data from the card, so back up important files in advance.
⚠️ Note: Formatting a memory card through your smartphone settings will completely destroy all data on it. Make sure that there are no important files on the card, or save them pre-on your computer.
Once installed, the system may suggest using the card as part of internal storage or as portable storage. For the purpose of transferring photos and media, it is recommended to choose a portable storage option that will allow you to easily retrieve the card and read it on other devices without losing access to data.

Set up automatic photo saving on SD-map
The most effective way to free up space is to set up the camera so that new images are immediately saved to an external medium. In Xiaomi's standard Camera app, this option is often hidden in additional settings. Open the app, click on the three bars in the upper right corner, and select Settings.
In the menu that opens, you need to find the section related to data storage. The interface may vary depending on the version. MIUI, But the logic remains the same. SD-The activation of this switch ensures that all new frames, including serial shooting and timelapses, will be recorded directly to an external drive.
- 📸 Open the Camera app and go to the settings menu through the top corner of the screen.
- 💾 Find the item "Save to" SD-map" and activate the switchboard.
- 🎥 Check the setting for video recording as it may require a separate turn on.
- ✅ Take a test shot and check its location through the file manager.
It is worth considering that some shooting modes, such as Portrait with complex processing algorithms or shooting in RAW, can still save copies to internal memory for quick processing by the processor.
💡
Use UHS-I or higher memory cards to shoot 4K video, otherwise recording may be interrupted due to low recording speeds.
Using a file manager to move files
If the photos are already taken and take up space in internal memory, you need to move them manually, and Redmi smartphones have a powerful File Manager tool pre-installed, launch the app and go to the section that displays the phone's internal storage.
Find the DCIM folder, and inside it is the Camera folder, and that's where all your images are stored by default, select the files you want or entire folders you want, click the "More" button (three dots), and select "Move" or "Copy," and the difference between those actions is significant: copying will leave the original in place, and moving it will delete it from internal memory after the process is complete.
| Action. | The result in internal memory | Result: SD-map | Recommendation |
|---|---|---|---|
| Copy | Files remain. | There's a duplicate. | For important archives |
| Move it | Files are deleted | Files are being transferred | To make room |
| Send. | Files remain. | A copy is created in a folder | For quick sorting |
After you select the action, the system will prompt you to specify the destination. SD-You can create a new folder, for example, a new folder, «Photos_2026», The process of moving a large number of files can take time, do not interrupt it and keep the screen on.
What to do if the “Move” button is inactive?
Gallery work and storage cleaning
The Gallery app in the MIUI shell also allows you to manage the location of files, although the functionality is more limited than the Explorer. You can select albums and change their display priority. However, for physical transfer of files, the gallery often acts only as a visualizer, not a file system management tool.
After transferring photos to the memory card, it is recommended to update the media library. Sometimes new files are not displayed immediately in the gallery or, conversely, the old "ghost" thumbnails remain on the list. To solve this problem, you can restart your smartphone or use the "Cleanup" function in the "Security" application by selecting the garbage scanner.
And you should pay special attention to the Thumbnails folder, which can grow to huge sizes. It has thumbnails for quick viewing in the gallery. If you've moved the originals but haven't cleared the gallery cache, the space may not be freed up as expected. Regularly cleaning the app cache helps keep the system on track.
- 🗑️ Go to the settings of the Gallery app and find the item “Clear the cache».
- 🔄 Restart the device so that the system re-indexes the media files to the SD-map.
- 📂 Check the “Recently Deleted” folder to make sure there are no images you need before you clean the file.
⚠️ Note: Do not delete system folders with names like Android, MIUI or.thumbnails in their entirety if you are not sure of their content, which can lead to malfunctioning of applications and loss of settings.
Solving Common Problems in Transfer
Users may experience a situation where the phone "sees" the card, but writes files to it. Often the reason is the permissions. When you first start the explorer or gallery after the system update, Android asks for permission to access the storage. If you accidentally refuse access, the functionality will be limited.
Another common problem is the “File is too big” error, which occurs when the card is formatted in the old FAT32 file system, which does not support files larger than 4 GB. To record large video files, you need to reformat the card to exFAT, which is supported by all modern Xiaomi smartphones.
If the transfer process is stuck at a certain percentage, maybe the card sector is damaged or the contact in the slot is broken. Try to retrieve and paste the card again, pre-switching off the phone. In rare cases, resetting the settings of the conductor applications through the Applications menu in the system settings helps.
💡
The exFAT file system is optimal for 64GB and higher memory cards, providing Android compatibility and support for large file sizes.
Optimization of work with external storage
To prolong the life of the memory card and maintain the speed of writing, it is recommended to periodically defragment or check for errors. Although Android does this automatically in the background, manual verification through a computer using the chkdsk utility or analogues will not be superfluous.
You might also want to consider using cloud services in conjunction with a physical map, such as setting up syncs for select albums to the cloud and storing the full archive on a physical map. SD-This will create a robust two-tiered data protection system: fast availability on the phone and backup on the Internet.
Check the status of the memory card regularly through the storage settings menu. The system will report wear and tear or need to be replaced if the recording speed drops to critical values. Timely replacement of the drive will save you from sudden loss of photos.
