How to transfer data to the right place SD-map in Xiaomi phones: apps, photos and files

Xiaomi smartphones based on MIUI Often face a lack of internal memory, especially in the budget models of the Redmi series or POCO s 32/64 GB of storage. Transfer of data to SD-The map seems like an obvious solution, but in the realities of Android 10+ and MIUI 12-14 This process has been complicated by Google's restrictions and security policies, and unlike older versions of Android, where the memory card could be made an "internal drive," most applications now block such a transfer, and library files require manual configuration.

In this guide, we will discuss all working methods of transferring data to SD-Xiaomi map – from standard tools MIUI bypasses with use ADB And third-party utilities. You'll learn how to do this:

• 📱 Move applications (including those that do not support) SD-mapping)
• 📷 Automatically save photos and videos to a memory card
• 📁 Move documents, music and downloads without losing data
• ⚙️ Set up SD-card as a portable or internal drive (with nuances for the MIUI)
• ⚠️ Avoid common mistakes that make the card stop being defined

Important: The instructions are relevant for MIUI 12, 13 and 14 (including global and Chinese versions), but some steps may differ on Xiaomi with Android 13/14 due to Google's tightening security policy.If your phone is released before 2019 (for example, Redmi Note 7 or Mi 9), you have a better chance of successfully migrating apps - in new models (Redmi Note 12, POCO X5), these features are greatly curtailed.

1. Preparation SD-maps: selection, formatting and nuances MIUI

Before you can transfer data, you need to properly prepare the memory card itself. Xiaomi has strict requirements for storage devices:

• 🔹 Speed class: minimum UHS-I (Class 10) or A1/A2 Class maps for applications. C4/C6 Suitable only for photos and music.
• 🔹 Volume: from 16 GB (but better 64)+ GB, since part of the memory will take the system in formatting as an internal drive).
• 🔹 File system: exFAT or FAT32 portable, ext4 — if the card becomes internal (automatically selected when formatting in the MIUI).

V MIUI There are two modes of operation. SD-map:

1. Portable drive – the card is used as a removable drive (you can easily retrieve it, but not all applications support writing to it).
2. Internal drive – the card becomes part of the system (applications can be ported, but the card cannot be retrieved without resetting).

⚠️ Note: If you select the "internal drive" mode", MIUI It will format the card by deleting all data, and then it will not be possible to read the card on other devices (for example, on a PC or camera) without full formatting, which is not recommended for cards with a volume of less than 64 GB, since the system reserves up to 20% of memory for service files.

To prepare the map:

1. Put it in. SD-card to slot (some Xiaomi models require you to turn off your phone).
2. Go to Settings → Memory → Memory Map.
3. Click Format as an internal drive (if you need to port applications) or Use as a portable drive (for photos and files).
4. Confirm the action and wait until it is completed (may take up to 5 minutes).

2. Transfer of applications to SD-Map: Standard and Hidden Methods

V MIUI 12-14 portability SD-The card is officially supported only for a portion of the software, and many programs (especially system and games) block this feature due to Android security policies. 10+. But there are workarounds.

Method 1: Standard Transfer through Settings

This method works for applications that explicitly support porting to SD. These are usually lightweight utilities (like FX File Explorer, VLC) or older games.

1. Open Settings → Applications → Application Management.
2. Select the application you want (such as Google Maps).
3. Press Warehouse. → Change. → choose SD-map.
4. Confirm the transfer and wait until it is completed (may take a few minutes).

⚠️ Note: After the transfer, the application may run slower, especially if SD-class C10 (not A1/A2). Some functions (such as widgets or notifications) may stop working:

• 🚫 System applications (Settings, Phone, Messages).
• 🚫 Applications with high performance requirements (e.g, PUBG Mobile, Genshin Impact).
• 🚫 Programmes with OBB-Files (additional game data).

Method 2: Transfer over ADB (for power users)

If the app doesn’t support menu porting, you can use Android Debug Bridge (ADB), which works even for system applications, but requires a PC connection.

Instructions:

1. Turn on Developer Mode on Xiaomi: go to Settings → About Phone and 7 times click on the MIUI version.
2. Return to Settings → Additional → For developers and enable USB debugging.
3. Connect your phone to your PC, install ADB drivers (for example, via Google’s Mi PC Suite or Platform Tools).
4. Open the command line on the PC and type: adb shell pm set-install-location 2 This command will force the system to install applications on the PC. SD-default-card.
5. To transfer an already installed application (such as WhatsApp), use: adb shell pm move-package com.whatsapp /storage/XXXX-XXXX (substitute XXXX-XXXX downhill SD-The map can be found through adb shell ls. /storage).

⚠️ Note: Not all applications will work after a forced transfer. For example, Google Play Services or Mi Account may crash with such an intervention. → System system → Backup.

• 🔧 Install Magisk and Bind Mount Module (for folder binding).
• 🔧 Use it. App2SD (root).

5. Compatibility table: what data can be transferred to SD in Xiaomi

Not all data types are equally well transferred to a memory card, and below is the compatibility table for MIUI 13/14:

💡

Nana SD-A card formatted as an internal drive can transfer more data, but this will reduce its compatibility with other devices and increase the risk of data loss when retrieving.

Typical errors and their solutions

When working with SD-And the problem with these Xiaomi maps is that users often have problems:

Mistake 1: "SD-Card damaged" or "Not supported"

Causes and solutions:

• 🔸 Incompatible file system: format the card in exFAT on PC via SD Card Formatter.
