How to transfer 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 nuances: from choosing the right map format to choosing the right card format (FAT32, exFAT or NTFS) pre-tuning MIUI In this article, we will discuss all the current methods of transfer, from manual copying of files to automated movement of applications, and also consider typical errors and their solutions.

Feature of Xiaomi devices (including Redmi models, POCO And Black Shark is a great deal of flexibility with external drives. MIUI 14+ The option “Expand internal memory” is available, which allows you to use the SD-But there are limitations to this mode: it becomes "linked" to the device and not readable on other gadgets, and we'll analyze when to choose this option and when to leave the card in "Portable storage" mode".

It is important to take into account technical limitations: not all Xiaomi models support cards with a volume of more than 1 TB, and the read / write speed depends on the class of the card (Class 10, UHS-I If you plan to port applications, you will need a card with high speed, otherwise the program will slow down. In this article, we will give a table of compatibility of cards with popular Xiaomi models (from Redmi Note 10 to Xiaomi 14 Pro).

1. Preparation SD-maps: selection, formatting and verification

Before transferring data, you need to properly prepare the memory card. The first thing you should pay attention to is the speed class. 10, but for applications and games it is recommended UHS-I (U1/U3) or A1/A2 (Optimized for random recording. Maps A2 Provide minimal delay when launching applications, which is critical for MIUI, where some of the data is cached on an external drive.

The next step is formatting. Xiaomi supports three file systems:

• 📁 FAT32 — Compatible with all devices, but limited to files up to 4 GB. Suitable for photos and music.
• 📁 ExFAT – Optimal for Files >4 GB (video) 4K, It's working on the disk. MIUI 12+ driverless.
• 📁 NTFS — It is rarely used in mobile devices, but may be required for specific tasks (e.g., connecting to a PC).

• ⚡ Enable "Fast Transfer" in the file manager settings (if available).

⚠️ Note: When transferring photos and videos in format HEIF/HEVC (Used in Xiaomi to save space, make sure that the target folder is on SD-The card supports these formats, otherwise the files may not open.

• 🔄 After the transfer, the application may run slower due to speed. SD-map.
• 🔒 Moving app widgets may disappear from the main screen.
• 📱 When extracted SD-Application maps will be unavailable.

A workaround for advanced users – using ADB (Android Debug Bridge. This method allows you to forcibly transfer some of the application data to the map, but requires an unlocked bootloader and root rights (which voids the warranty). ADB:

adb shell pm set-install-location 2 # Set SD-map as default location


adb shell pm get-install-location # Check the current location

⚠️ Attention: Forced transfer through ADB This can cause problems with applications, especially if SD-The card has a low write speed (e.g. Class 4) and only test on non-critical programs.

4. Automatic data transfer: settings MIUI

MIUI It offers built-in tools for automating data transfer, for example, in the "Storage" section you can enable the option "Save new files to the data port". SD-It's relevant to the map:
