How to transfer files from Xiaomi phone to memory card: full guide

Overflowing internal memory is a problem that every Xiaomi, Redmi or Poco smartphone owner will face sooner or later. When storage is clogged with photos, videos and messenger cache, the system starts to work slower and installing new applications becomes impossible, in such situations, freeing up space becomes a priority for maintaining the performance of the device.

The most efficient and budget-friendly solution is to use a microSD card, which allows you to instantly increase the amount of storage available without having to delete important data or buy a new gadget.

But just inserting the drive is not enough, and to keep the system stable and files safe, you need to configure the MIUI correctly and transfer the data, and in this article we will discuss all the nuances of working with external drives on Xiaomi smartphones.

Preparation and installation of a microSD memory card

The first step is to physically install the drive. In most modern Xiaomi models, the memory card slot is combined with the slot for the second. SIM-You'll need a special paper clip that comes with the kit, or a thin needle to extract the tray.

Put the memory card in the tray, keeping the contacts in line. Usually, there's a little diagram on the tray showing the correct position of the chip. Once installed, insert the tray back into the phone before the characteristic click. The system should automatically identify the new device and suggest that it be configured.

If you don't notice, check the status of the drive in your settings. Go to Settings → Memory or Settings → Phone → Memory. This displays information about whether the device sees the inserted drive and how much free space is available.

💡

Use UHS-I or UHS-II speed memory cards from trusted brands (SanDisk, Samsung, Kingston). Cheap cards can run slowly and fail quickly, resulting in data loss.

It is important to understand the difference between storage formats: the card can work as a portable storage for media files or be formatted as part of internal memory, the former being preferred for photo and video transfer, as it is compatible with other devices.

Configuring a memory card as an internal storage

In the shell. MIUI There is a function that allows you to use SD-This allows you to install applications directly on the external drive and store their data there. To activate this function, you need to format the card, which will delete all the files on it.

The formatting process is triggered through the settings menu. Select your card from the storage list and click the Format button. The system will warn you of data loss. Once confirmed, a process will begin, which can take several minutes depending on the storage volume.

⚠️ Warning: Once you format the card as an internal storage device, it's encrypted and linked to a particular phone, and you can't just insert it into another smartphone and read the data without re-formatting it.

Once the procedure is complete, the system will suggest moving the already installed applications and media files, agreeing to the transfer to immediately free up space in the internal partition, and now some of the system processes and application data will be written to an external medium.

It is worth noting that the speed of applications installed on the SD-The card may be lower than the internal flash memory of the phone, because of the physical limitations of the interface and the speed of the drive itself, so it's better to leave the applications that are critical for performance in the internal memory.

Manually move photos and videos through the Explorer

The most common memory card scenario is storage of a media library. Xiaomi's camera defaults to storing images in internal memory, but this setting is easy to change, and you can manually move existing archives.

Use the standard File Manager app to manage files, which has a user-friendly interface that allows you to move large amounts of data quickly. Open the app and find the DCIM folder that stores your photos and videos from the camera.

Select the files or folders you want with a long press. At the bottom of the screen, you'll see an action menu. Select "Move" or "copy." Then, at the root menu of the explorer, select yours. SD-map and specify the target folder, for example, create a new folder Photos_Archive.

• 📂 Open the Explorer app and go to internal storage.
• 📂 Find the folder. DCIM → Camera for Photos or MiVideo for Video.
• 📂 Select files, click “More” and select “Move».
• 📂 Go to section. SD-maps and press "Insert».

When moving large video files, the process can take time: Do not turn off the screen or close the Explorer app until the operation is complete.

Once you move the files, you should check if they're openable, open the gallery, find the displaced pictures, and make sure they're displayed correctly, and then you can delete the originals if you've used the copy function instead of moving them.

Automatically save new photos on SD-map

To avoid manual transfers in the future, set up the camera to automatically save new images immediately to the memory card, which eliminates the need to constantly monitor the filling of internal memory.

Open the Camera app. Click on the menu icon (three bars) in the top right corner and select Settings. Scroll down to the Save section. Here you will see the Save to Save to Settings switch. SD-map».

Activate this switch. All new photos and videos will be recorded directly to the external drive, and in the gallery they will be displayed in a shared tape, but physically occupy space on the map.

It should be noted that when shooting high-resolution (4K or 8K) video or using slow-motion modes, the camera can ignore the setting and save the file to internal memory. This is done to ensure the stability of the recording, as the data flow may be too large for the memory card.

Transfer of applications and data to an external drive

Not all applications can be migrated to a memory card, which is decided by the app developer and depends on the version of Android, but for many programs, this is available through system settings.

Go to Settings. → Annexes → Application management. Select the application you want from the list. If portability is possible, you'll see a memory or storage button, and inside it you'll see the option to modify or move to SD-map».

When you move an application to a map, some of the data will still be stored in internal memory, which is necessary to ensure that services are quickly launched and run, and it may not be possible to completely free up space from the application, but a significant amount of cache will be moved.

For games with large data packets (cache, textures, levels), portability can be especially useful. However, if the game starts to load long or fly out, try to return it to internal memory.

Possible problems and ways to solve them

Users may experience read or write errors during operation, often with the file system as the problem is with Android prefers the exFAT or FAT32 format for external drives.

If your phone offers to format a card, but you're afraid of losing data, first connect it to your computer through a card reader, copy all the important files on your PC, then format the card on your phone and return the data back.

⚠️ Note: If the system is constantly writing «SD-Card damaged" or "Formatting required" may be physical damage or a fake with less than claimed volume.

Another common problem is the slow operation of the interface when viewing photos in the gallery, which can occur if the memory card contains tens of thousands of small files, in which case it is recommended to defragment the map every few months via a PC or clear thumbnails.

💡

Regular maintenance of the memory card and checking its condition help to avoid sudden data loss and prolong the life of the drive.
