Transfer files to Xiaomi SD card: the complete guide

Modern Xiaomi and Redmi smartphones, despite excellent optimization, often face a lack of free space. Users actively shoot 4K videos, install heavy games and accumulate gigabytes of media in messengers, which leads to overflow of the internal drive. When the system reports a critical lack of space, the device’s performance drops, and new applications stop being installed.

Fortunately, most of the brand’s models support microSD card installation, which allows you to instantly expand storage. Moving data is not just copying files, but competent folder management, which will help you avoid chaos in the file system. In this article, we will discuss all the nuances of working with an external drive on the shell of MIUI.

Before you start the process, it is important to make sure that your memory card is properly formatted and well-functioning. If you insert a new drive, the system often suggests formatting it right away. Be sure to back up important data before formatting, as this process will completely clear the card.

Preparation of memory card and settings Xiaomi

The first step is to physically install the card and set it up in the system, insert the MicroSD into the SIM card tray of your Xiaomi smartphone, and then go to the settings menu, and you need to find the storage partition to make sure that the phone correctly recognizes the new volume.

Click on Settings → About Phone → Storage. Here you will see a graph of occupied space and a list of connected drives. If the card is correctly identified, the system will prompt it to use. Pay attention to the choice of mode: you can use the card as a portable storage or as part of internal memory.

• 📱 Portable storage – the card works like a regular flash drive, files are visible on PCs and other devices.
• 💾 Internal memory – the system encrypts the card, and it becomes available only to this smartphone (Adoptable Storage function).
• ⚙️ Formatting – the process of creating a file system, mandatory for a new card.
• 🔒 Security – when selecting internal memory mode, data is protected from retrieval on other devices.

⚠️ Note: When you switch the card to Internal Memory mode, all data on it will be deleted. Make sure that there are no important files on the card, or copy them in advance to your computer.

If you plan to transfer the card to your computer or other phone often, you should leave portable storage mode, and if the main goal is to maximize the amount of space for installing applications and games, then formatting for internal memory will be the best solution for your Redmi Note or Mi model.

Use of the standard MIUI Conductor

The easiest and safest way to move files is to use the built-in file manager, which is called Explorer in the MIUI shell, and has a user-friendly interface with colored category icons. Open the app and go to the folder tab to see the directory structure.

At the top of the screen you will see a switch between the “Internal Drive” and «SD-To start, select the internal memory. Find the folders that take up the most space. DCIM (Photos and videos from the camera, Download (downloads from the browser) and folders of messengers, for example, WhatsApp or Telegram.

You can select the files you want with a long press. At the bottom of the screen, you can see an action menu. You can click Copy or Cut. The difference is that copying will create a duplicate file by taking up space in both storages, and cutting out will move the file, freeing up space in the source. Then go to the root. SD-maps through the conductor menu.

In the window that opened SD-Create a new folder with a clear name, for example, Archive_2026, So you don't mix old and new files. Press Insert. Wait until the process is over. The speed of copying depends on your memory card's speed class and file size.

Transfer of photos and videos from the Gallery

The media library is the main consumer of space on Xiaomi smartphones. The high resolution of modern matrices leads to the fact that one photo can weigh 10-15 MB, and a minute of video in 4K – hundreds of megabytes. For mass work with media files, the most convenient is to use the standard application “Gallery”.

Open the Gallery and go to the Camera or Screenshots album. Press and hold your finger on one of the photos to activate the selection mode. Then you can swipe a whole group of pictures or click the "Select All" button on the menu. After selecting, click on the three dots in the corner of the screen and select Move.

The system will suggest you choose your destination. SD-The good thing about this method is that it automatically updates the library database so that your photos don't get lost, but if you move thousands of files at once, it can take a lot of time, and the phone can get a little warmer.

⚠️ Note: After transferring the photo to SD-Map, make sure that in the settings of the Camera (Settings) → Retention on SD-map) has enabled the option to record new images directly to the external drive, which will prevent the internal memory from being refilled.

If you use cloud services like Google Photos or Xiaomi Cloud, make sure that the sync is complete before transferring.This will create additional insurance in case of damage to the memory card. SD-The card may be lower than the internal memory, so viewing heavy video in high bitrate may be accompanied by buffering.

Moving apps and games to an SD card

The issue of porting installed applications (APKs) to a memory card in modern versions of Android and MIUI has been ambiguous, with Google officially limiting this option for the sake of system stability and data security, and some methods still work, especially for older games or applications whose developers have provided such a feature.

To check for portability, go to Settings → Annexes → All applications. Select the program you want. If you click "Change" or "Move to" SD-The map is active (not grey), you're lucky. Press it and follow the instructions. However, for most system applications and popular software, this button will not be available.

For games that support cache files (e.g. Asphalt, PUBG), it is often possible to move only heavy resources. Some launchers and file managers allow you to create symbolic links, tricking the system, but this requires the presence of Root rights. Without superuser rights, experimenting with system files is not recommended, as this can lead to unstable Xiaomi operation.

• 🎮 Cache games – often takes up more space than the application itself, it can be carried manually.
• 📦 Official support – depends on the app developer, not the phone setup.
• 🛠️ Root rights – give full access, but deprive of guarantees and can disrupt the operation of banking applications.
• 📉 Performance – Launching games with slow speed SD-Cards can cause "freezes" and long loads.

If the transfer button is inactive, don't despair. The main focus of games is on resources that can often be reassigned to the settings of the game itself or move the cache folders manually through Explorer, changing the paths. But beware: improper movement of cache files will cause the game to stop running.

💡

Use UHS-I or UHS-II memory cards with high write speeds. Cheap cards can become a bottleneck, making the phone slow even if the internal memory is free.

Working with messengers: Telegram and WhatsApp

Messengers have long been the main memory eaters: WhatsApp, Telegram and Viber store every photo and video they receive in their phone’s memory, and fortunately, these apps have built-in tools to change the way they store data.

Telegram is the most flexible. Go to Settings → Data and memory → Save Way. You can select "Other" here and point any folder to yours. SD-All new files will be downloaded there. For existing media files, you will have to use Explorer and move the Telegram folder from internal memory to the map, and then make a simlink (if there is Root) in the phone settings, or just leave the files where they are, freeing up space.

WhatsApp is a little more complicated due to changes in the structure of Android folders 11+. The path to data is now in the Android/media/com.whatsapp. You can move the Media folder to SD-However, for WhatsApp to keep writing data there, it may require a complicated procedure to rename folders or use third-party utilities to redirect paths. MIUI This is the safest option for archiving.

⚠️ Note: Do not delete messenger folders from internal memory until you make sure that the application works correctly with the new save path. Otherwise, you may lose your correspondence history or media files.

Cleaning messenger cache regularly is a good habit, even if you have one. SD-Maps, temporary files can fragment and take up space in the system partition. Use the built-in cleaning tools in Xiaomi storage settings.

Problem Solving and FAQ
