How to completely transfer data to SD-Map in Xiaomi smartphones: from files to applications

Transfer of data to SD-The map in Xiaomi smartphones is a challenge that users face when they lack internal memory. Despite the apparent simplicity, the process has nuances: from choosing the right map format to choosing the right card format (FAT32, exFAT or NTFS) pre-tuning MIUI In this article, we'll look at all the ways you can transfer, from media files to applications, including hidden system capabilities and bypassing manufacturer constraints.

It is important to understand that Xiaomi artificially limits some functions of working with the company. SD-maps in the latest versions MIUI (For example, porting applications to a memory card is not officially supported on all models, and formatting as an internal drive (Adoptable Storage) is only available for devices on pure Android or with an unlocked bootloader. We will show workarounds and alternative solutions.

Why Xiaomi is limiting the work with SD-map

Xiaomi’s MIUI-based smartphones have a number of software limitations when working with external drives, and here are the key reasons:

• 🔒 Security of data: MIUI Blocks the transfer of some system files and applications to SD-card to prevent damage when the drive is removed.
• 📉 Performance: Class Memory Cards UHS-I or lower slow down applications, so the system limits their installation on external media.
• 📱 Google Policy: Starting with Android 6.0, Adoptable Storage (Use) SD As internal memory, it became optional for manufacturers.
• 💾 Fragmentation of files: Frequent data movement between internal and external memory increases wear and tear of flash drives.

However, these limitations can be circumvented, such as the ADB (Android Debug Bridge) method for porting applications, and the MIUI built-in tools for media files.

Preparation SD-maps: format selection and compatibility check

Before transferring data, you need to format the memory card correctly, and the choice of file system determines which files can be stored and how quickly they will be read.

For Xiaomi, exFAT is optimal if your model runs on MIUI 10 or later. Maps up to 32 GB can be left in FAT32.

1. Put it in. SD-card in a slot (or adapter for models without a separate slot).
2. Go to Settings → Storage → Memory Map.
3. Click Format → As a portable device (or as an internal device if you need to expand memory).
4. Select exFAT (if available) and confirm the action.

⚠️ Attention: Formatting as an internal storage will bind the card to a particular device, and once extracted, the data on it will be inaccessible without resetting.

Method 1: Transfer media files (photos, videos, music) through Explorer

The easiest method is to use the built-in MIUI Explorer. It allows you to move files without additional programs, but has a limitation: you can not transfer system data or installed applications.

Instructions:

1. Open the Files app (the folder icon on the desktop).
2. Go to the Internal Memory section and select a folder (e.g. DCIM for photos or Download for downloads).
3. Press and hold the file/folder, then tap Allocate (or select specific files).
4. Click Move (arrow icon) and select SD-map.
5. Confirm the transfer. Speed depends on the card class (UHS-I U3 or higher is recommended).

To speed up the process, you can use the packet mode:

Use a class card UHS-I U3 higher|

Disable background applications in battery settings|

Move files at night (less system load) |

Check the card for errors after transfer through Settings → Warehouse → Verification SD-map

-->

If the files are not transferred, check:

• 🔌 Connect the card (reboot the device if it is not determined).
• 📁 Access rights: C Settings → Annexes → Permits → Warehouse enable access to Files.
• 🛠️ Map integrity: Damaged sectors can block the record.

Method 2: Transfer applications to SD-map ADB (advanced)

Officially. MIUI does not support the transfer of applications to SD-This can be done via Android Debug Bridge (ADB). The method works for most models (Redmi Note 10 Pro, POCO X3 Pro, Mi 11, etc., but requires unlocking Developer Options.

Steps:

1. Activate Developer Options: Go to Settings → About Phone. Tap 7 times on the MIUI version until the notification appears.

USB debugging

Settings → Additional → For Developers

ADB Tools

adb devices

Make sure the device is identified.

package.name

adb shell pm set-install-location 2

This command forces the system to install new applications on the SD-default-card.

adb shell pm move-package package.name

Redmi 9A

Failure [NOT_MOVED: -110]

⚠️ Note: Transferring system applications (e.g. com.miui.home) can cause a cyclical reboot of the device. → System system → Backup.

An alternative way is to use apps like AppMgr III (available on Google Play), which automate the process through the same ADB but with a graphical interface.

Method 3: Use SD-The card is an internal memory (adoptable storage)

Adoptable Storage feature, which appeared in Android 6.0, allows you to format SD-The card is part of the internal storage, but Xiaomi has disabled this option in the MIUI There are two ways to get around the restriction:

Method 1: Hidden menu (for some models)

On some devices (POCO F1, Mi A2), the option is saved in the hidden menu:

1. Put it in. SD-map.
2. Open the Settings → Storage → Memory Map.
3. Slip on the three dots in the top right corner and select Storage Settings.
4. If you have the option to format as internal, choose it.

Method 2: Through ADB (Universal)

Other models will require ADB:

1. Connect the device to the PC and activate Debugging via USB.
2. Enter the command: adb shell sm list-disks Remember the disk ID (e.g., disk:179.64).
3. Format the card: adb shell sm partition disk:179.64 private (replace 179.64 with your ID).

After formatting:

• 📲 The card will be part of the internal memory and will be encrypted.
• 🔄 It can't be removed without resetting the settings.
• ⚡ The speed of work depends on the class. SD (recommended UHS-II).

💡

If the device starts to slow down after formatting as internal memory, return the settings to Settings → System → Reset → Reset Storage settings. This will delete all data from the card, but restore it as a portable device.

Method 4: Automatically transfer files through camera settings and downloads

Many users do not know that MIUI It allows you to automatically save new files to SD-It eliminates the manual transfer.

Setup for the Camera:

1. Open the Camera app.
2. Put the pin on the gear badge (⚙️) Or swipe up to open the settings.
3. Select a Retention Site → Memory map.
4. Restart the camera to make the changes effective.

Setting up for Downloads:

1. Open Settings → Applications → Application Management.
2. Find Downloads (or Browser if you use Mi Browser).

For WhatsApp and other messengers:

• 📱 Open the chat settings → Warehouse and data.
• 📁 Select Save Media to Memory Card (if option is available).
• 🔄 For Telegram, go to Settings → Data and memory → Telegram folder.

⚠️ Attention: If SD-The card is turned off during recording (for example, when shooting a video in the video). 4K), Check it for high-speed recording. C10/U3 And below may not be able to cope with the flow of data.

Problem Solving: Card is not defined, files are not portable

If Xiaomi can't see SD-card or errors occur when transferring, use this instruction:

If the card is identified but the files are not copied, try:

1. Connect your smartphone to your PC and transfer data through MTP-protocol.
2. Use an alternative conductor (e.g. Solid Explorer or FX File Manager).
3. Check the card on another device (it may be locked or damaged).

To diagnose the condition SD-Enter the cards at the terminal ADB:

adb shell dumpsys media.drm

If the output has a line sdcard: unmounted, the problem is mounting – try to restart the device or replace the card.

💡

If SD-The card is often disabled when recording, check it for counterfeit using the utility H2testw (Windows or F3 (macOS/Linux). Fake cards can have an understated speed and volume.
