How to transfer files to Xiaomi memory card: step-by-step guide

Owners of modern Xiaomi smartphones often face a lack of built-in storage, especially if the device is equipped with a modest amount of memory of 64 or 128 GB. Installed applications, accumulated messenger cache and high-quality photos quickly fill the free space, slowing down the system. Transferring user data to an external drive becomes the only effective way to unload internal memory without losing important information.

MIUI and the new HyperOS provide flexible tools to manage the file system, allowing you to manually move large amounts of data, especially for those who shoot 4K video or store huge music libraries directly on your phone. In this article, we will discuss all available methods of transfer, from standard tools to the use of third-party file managers.

Preparation of memory card and smartphone for work

Before you start moving data, you need to make sure that the microSD card is correct and formatted correctly.Put the card into the smartphone slot (often it is combined with the second sim tray) and wait for the corresponding notification to appear in the “curtain” of the system. If the card is new, the system will suggest configuring it, but for transferring files it is better to use the file manager for accurate control.

It is important to understand the difference between file system formats. FAT32 or exFAT is the best format for storing photos and videos, as they are compatible with most devices, including cameras and computers. Formatting a card inside a phone is the best way to avoid reading errors in the future.

• 📱 Make sure the smartphone is turned off before removing the tray for SIM and SD-map.
• 💾 Check the card for errors by connecting it to the PC through the card reader.
• 🔄 Backup important data before formatting.

⚠️ Note: Formatting a memory card completely erases all data on it. Be sure to copy important files to your computer before starting the procedure.

Once you have installed the card, go to the storage settings to make sure the system sees the new volume. In some cases, it may be necessary to reboot the device so that Android properly mounts the external drive and assigns it a letter or path in the file system.

Using a built-in conductor to transfer files

The standard Explorer (or Files) tool in the MIUI shell is the easiest and safest way to move data. You don't need to install additional applications, since the integrated manager functionality fully covers the needs of the average user.

To get started, open the app and go to the section where the source data is stored, such as the Internal Drive folder. Find the DCIM/Camera directory, where the default photos and videos taken on the smartphone camera are saved. Select the desired files with a long press or select the "Select All" option from the menu.

After selecting files, click on the three dots in the corner of the screen or the "More" button and select the "Move" or "Copy" action. Copying is safer, as the source files will remain in place in case of an error, and moving immediately frees up space. Then, in the navigation menu, select your memory card (usually denoted as SD Card or MicroSD) and go to the target folder.

In the confirmation window that opens, the system will show the number of objects being moved and their total weight. Click "Insert" or "OK" and wait for the progress bar to be completed. The speed of the process depends on the speed class of your memory card and the size of the files.

If the movement process is frozen or extremely slow, check if the heavy app is working in the background. It is also worth making sure that the smartphone screen does not go out during the operation, although modern Xiaomi systems usually block falling asleep during active file operations.

Transfer data using the Files by Google app

If a standard Explorer seems uncomfortable or doesn’t work properly, Files by Google is the official file manager from the search giant, which is often pre-installed on smartphones or available on the Play Market, and can automatically sort files and offer convenient tools to clean up memory.

When you start the app, go to the Overview tab at the bottom of the screen, and here you will see two main sections: Internal Memory and «SD-The interface is in the style of Material Design, which makes navigation between folders simple and understandable even for beginners.

Go to internal memory, find the files you want, and highlight them. In the bottom menu, a three-dot button will appear, where you need to select "Move to..." The system will offer a list of available storage facilities — select yours. SD-A unique feature of this method is the ability to create new folders right during the movement.

The advantage of using a third-party manager from Google is a more stable work with large amounts of data. While the standard MIUI utility can fly out when moving thousands of small files, Files does this more sustainably, ensuring data integrity.

Setup the camera to save the photo on SD-map

To avoid manually transferring files every time, you can set up automatic saving of new images directly to an external drive, especially for mobile photography enthusiasts who take hundreds of frames a day, and this will prevent internal memory from filling up quickly.

Open the Camera app and click on the three bars in the upper right corner to enter the settings. In the list of options, find the item "Save to the SD-map or priority SD-"Maps" and activate the switch. From now on, all new photos and videos will be recorded along the way. /storage/sdcard1/DCIM/Camera.

• 📸 The quality of shooting will not change, but the speed of serial shooting may decrease.
• 💾 Make sure your memory card has a fast write speed (grade 10 and above).
• ⚙️ When the card is disabled, the photos will be stored in the internal memory again.

It’s worth noting that some shooting modes, such as 8K Video or high-resolution slow motion shooting, may ignore this setting, and the system will force such heavy files to be stored internally to ensure the recording process is stable and prevent frame loss.

⚠️ Note: If you remove the memory card while shooting the video, the current file will be corrupted and the camera may stop responding before the app restarts.

💡

Use UHS-I or UHS-II series memory cards to shoot 4K video to avoid interruption due to low buffer filling speeds.

Transfer applications to a memory card: myths and reality

The issue of transferring installed applications to SD-Xiaomi's map is one of the most complex. In modern versions of Android (starting with 6.0 and up), this feature has been significantly limited by the developers for the sake of security and stability. Now you can move far from every application, and often this requires activating hidden modes.

The standard Settings → Applications → Application Management allows you to see if a program takes up space on the map. If the Move button is inactive (gray), then the application developer has banned its installation on an external medium, this is typical for system services, banking applications and instant messengers.

There's a method through the developer mode that allows you to force the transfer.

1. Go to Settings. → About the phone and 7 times press on the "Version" MIUI».
2. Go to the Extra. → For developers.
3. Find the item “Allow applications to be saved on an external drive” and activate it.

However, even after turning on this option, many applications may not work correctly: widgets may disappear and notifications stop coming.Moving Google system applications and services to a memory card is strictly not recommended, as this can lead to a cyclical restart of the smartphone (bootloop).

💡

Transfer of applications to SD-A card on modern Android smartphones is only possible for a limited number of programs and often leads to a decrease in their performance.

Solution: What to do if your phone can't see files

Sometimes, after transferring files, users find that the gallery is not displaying new photos, or the music player does not see the tracks, most often the problem lies in the absence of a media index. Android must scan the new content of the map to update the databases of media files.

Try restarting your smartphone after you transfer the data. If that doesn't work, check for the.nomedia file in the photo folder on your memory card. This hidden file prevents the system from scanning the folder for media content. Delete it through the file manager with the hidden file display function.

Also make sure that the access rights of the gallery app allow reading of external memory. Go to Settings → Apps → Gallery → Rights and make sure that access to Files and Media Data is enabled. Without this permission, the application will not physically be able to show you the contents of the map.
