Transfer of data to SD-Map in Xiaomi smartphones: all ways and nuances

Transfer of data to SD-The map in Xiaomi smartphones is a challenge that most users face when they lack internal memory. Despite the apparent simplicity, the process has a number of nuances: from choosing the right map format to choosing the right card format (FAT32, exFAT or NTFS) to the specifics of the work with MIUI In this article, we will discuss all the current methods of transfer, from standard system tools to third-party applications, and also consider typical errors and their solutions.

It is important to understand that Xiaomi limits the ability to work with the SD-maps in new versions MIUI (starting from 12+). For example, Adoptable Storage is officially unavailable on most models after 2020, but there are workarounds that we’ll discuss below. Also, we will focus on the transfer of applications – here the algorithm differs from working with photos or music.

If you are using the Redmi Note 12, POCO X5 Or the flagship Xiaomi 13 series, the instructions in this article will be tailored to your model, so for ease of use, we've divided the material into blocks by data type and portability, and added a format compatibility table. SD-Maps with different Xiaomi devices.

1. Preparation SD-maps: selection and formatting

Before transferring data, you need to properly prepare a memory card. Xiaomi supports microSD up to 2 TB (theoretically), but in practice, cards up to 512 GB of UHS-I U3 or A2 class work more stable. For multimedia (photos, videos) U1 class is enough, but for applications it is better to choose A2 - it is optimized for random read / write operations.

Formatting is more complicated. MIUI offers two options by default:

• 📁 Portable storage – the card is used as a removable drive (files can be transferred manually, but applications cannot be installed on it).
• 🔄 Internal Storage – The card is formatted as part of the system (partition) ext4), But this mode is not available on all models.

For most users, the first option is the right one, but if you want to use the card as an extension of internal memory, you need a workaround through the ADB (Android Debug Bridge), which is the details in the application port section. Importantly, once formatted for internal storage, the card will not be read on other devices without being completely cleaned!

⚠️ Note: ExFAT cards may not work properly with files larger than 4GB on some Xiaomi models (e.g. Redmi) 9A). If you plan to store large video files, format the map into NTFS PC.

2. Transfer files through a standard file manager

The easiest way to transfer is to use the built-in Files app (or Mi File Manager), which is pre-installed on all Xiaomi smartphones and supports batch copying, cutting, and cloud services.

1. Open the Files app and go to the Local Storage section.
2. Select a folder with data (for example, DCIM for photos or Download for downloads).
3. Press and hold the file/folder, then mark the rest or tap Select All.
4. Click More → Copy (or Cut if you want to delete the originals).
5. Go to section. SD-map, select the target folder and click Insert.

To speed up the process, you can use the Move function instead of copying, which will free up space on the internal drive. Note that some system folders (such as Android or MIUI) may be hidden. To see them, tap the three-point in the upper right corner and select Show hidden files.

If the files are not copied, check:

• 🔋 Adequate battery power (below 15%, the system can block operations).
• 📶 Stability of connection of the card (try to remove and insert it again).
• 🛡️ No restrictions in security settings (Settings) → Annexes → Permits → Warehouse).

3. Transfer of applications to SD-map: restrictions and workarounds

Transferring applications to SD-map MIUI It's more complicated than files. MIUI 12, Xiaomi removed the standard portability feature from the settings menu.However, there are several working methods:

Method 1: Through application settings (for individual programs)

1. Go to Settings → Applications → Application Management.
2. Select the desired application and tap the Warehouse.
3. If the option to Change is active, select SD-map and confirm the transfer.

This method only works for a fraction of applications (usually those that support external storage by default, such as some games or instant messengers).

Method 2: ADB (for advanced users)

If the port option is blocked, you can forcefully move the application through ADB.

1. Turn on Developer Mode (7 times tap the MIUI version in Settings → About Phone).
2. Activate Debugging by USB in Settings → Additional → For developers.
3. Connect the phone to the PC, open the command line and type: adb shell pm set-install-location 2 This command forces the system to install applications on the PC. SD-default-card.

⚠️ Note: Transfer of Google system applications or services to SD-The card can lead to malfunctions in the work MIUI. Don't Move: Google Play Services, MIUI System, Security.

This setting is only valid for new files. Pre-existing photos and videos will have to be manually transferred (see section 2). 4K or 8K Some Xiaomi models (such as the Xiaomi 12 Pro) can ignore the settings and save files to internal memory due to write speed limits on the device. SD-map.

To automatically back up existing photos to the map, you can use the Google Photos app:

• 📷 Go to Settings. → Backup and synchronization.
• 📁 Choose Quality. → Original (if it is important to keep without compression).
• 🔄 Enable the option to Save copies on the device and specify SD-map as target storage.
