How to transfer files to Xiaomi memory card: all ways + error solving

Transferring files to a Xiaomi memory card seems like a simple task – until you face restrictions. MIUI, Formatting errors or sudden inaccessibility SD-Unlike other Android devices, Redmi smartphones, POCO Mi and Mi often require additional manipulations, from manually mounting the drive to changing the settings for applications. This article covers all the current ways of transferring data (photos, videos, documents, applications) taking into account the features of firmware. MIUI 12–14 and typical user errors.

We will analyze not only standard methods through Explorer and Settings, but also alternative options - from use to use. ADB To force applications to be moved to bypass the write restrictions that Xiaomi imposes "for security," a separate block is dedicated to solving common problems: when the card is not identified, files are not copied or disappear after a reboot "SD-Map damaged" or "No access - here you will find working ways to restore.

Important: instructions adapted to modern models (Redmi Note 12, POCO X5, Xiaomi 13 and newer, but applicable to older devices (subject to the current version) MIUI). For owners of devices with a hybrid slot under two SIM or SIM+SD added nuances on the priority of connection.

Memory card preparation: formatting and compatibility check

Before transferring files, make sure your SD-The card is compatible with the device and formatted correctly. Xiaomi supports microSD cards up to the size of the card. 1 TB (depends on the model), but for stable operation, class drives are recommended A1/A2 or UHS-I/UHS-II (For example, SanDisk Extreme or Samsung EVO Plus).

If the card is new or has been used in other devices, it must be formatted directly in the smartphone, which will delete all data, but will configure the file system to the requirements of MIUI.

1. Insert the card into the slot (when the phone is turned off, if the slot is hybrid).
2. Turn on the device and wait for the identification of the drive.
3. Go to Settings. → Memory. → SD-map.
4. Tap Format → Internal Memory (if you want to use the card as an extension of internal memory) or Portable Storage (for normal use).

💡

If the card is not defined after formatting, try formatting it on a PC to an exFAT file system (for cards >32 GB) or FAT32 (for cards ≤32 GB) using the SD Card Formatter utility from the SD Association.

Pay attention to the types of formatting:

• 📱 Internal memory: The card becomes part of the system (you can port applications), but it cannot be retrieved without losing data.
• 🗃️ Portable storage: the card works as a removable drive (files can be copied/deleted without restrictions.

⚠️ Note: If you chose the internal memory format and then extracted the card, MIUI It can block access to files before re-mounting. Always safely remove the drive through Settings → Memory. → Extract SD-map.

2. Method 1: Transfer files through standard MIUI Explorer

The easiest method is to use the built-in Explorer (the Files app). It allows you to copy/move data without additional tools, but has limitations: some system files (for example, the application cache) will not be able to transfer.

Step-by-step:

1. Open the Files app (the folder icon on the desktop).
2. Go to Device (Inner Memory) and find a folder with files (for example, DCIM for photo or Download for downloads).
3. Select files with a long tap → click More → Copy (or Cut).
4. Go back to the root directory, select SD-map and paste files into the desired folder.

If the Cut/Copy option is inactive:

• 🔒 Check if files are protected from recording (e.g. screenshots of system applications).
• 📵 Make sure the card is not connected to the PC in File Transfer mode (disable). USB-cable).
• 🔄 Restart your phone - sometimes MIUI strips off access rights SD-map.

3. Method 2: Use of a computer (USB-cable)

If it takes too long to transfer over a phone (for example, when copying tens of gigabytes of video), it is more convenient to use a PC, and this is also true if MIUI blocks access to certain files.

Option 1: Connecting your phone over USB

1. Connect Xiaomi to your computer with a cable (preferably original).
2. On your phone, select File Transfer (MTP) mode in the connection notification.
3. Open This Computer – Two Disks Should Appear: Internal Memory and SD-map.

Method 3: Transfer applications to SD-map (with limitations) MIUI)

Unlike the “pure” Android, MIUI It greatly limits the ability to transfer applications to SD-Officially supported only transfer of part of the data (not the very APK-It's not for all programs, but there are workarounds.

The official method (does not work for all applications):

3. If the Change option is active, tap it and select it. SD-map.

If the option is not available:

• 🚫 System Appendix (cannot be moved).
• 📵 The card is formatted as Portable Storage (you need to reformat it into Internal Memory).
• 🔧 The app does not support portability (e.g. WhatsApp, Google Play Services).

Alternative method through ADB (for advanced users):

If MIUI blocks the transfer, you can force the installation location via ADB:

adb shell pm set-install-location 2

This command will force the system to install applications on SD-Warning: After execution, some programs may not work stable!

5. Method 4: Automatically transfer photos and videos through the Xiaomi Gallery

MIUI It has an automatic backup function for media files on SD-This is convenient if you take pictures often and don't want to manually transfer files.

How to set up:

Limitations:

• 🚫 Files downloaded from instant messengers (Telegram, WhatsApp) are not copied).
• 📵 If the card is retrieved, backup is skipped.

💡

Local backup in Xiaomi Gallery does not replace cloud backups. SD-The map can be lost if it is damaged. For reliability, use additional Google Photos or Mi Cloud.

6. Solving common problems when working with SD-card

Even after successful file transfer, Xiaomi users often encounter errors, and let’s look at typical situations and ways to fix them.

Problem 1: The map is not defined or requests formatting

Causes and solutions:

• 🔌 Bad contact: Remove the card, wipe the contacts with alcohol and paste back.
• 🛠️ Damaged file system: connect the card to your PC and execute the command chkdsk X: /f (where X is the letter of the disk).
• 🔋 Power shortage: If the card is only determined after rebooting, try disabling Quick Boot in Settings → Battery.

Problem 2: Files disappear after rebooting

This happens if the card is formatted as internal memory, but not encrypted.

1. Make a backup of the data on the PC.
2. Go to Settings. → Memory. → SD-map → Settings → Formatted as internal (data will be deleted!).
3. After formatting, transfer the files again.

Problem 3: You can’t write files to a card (“Read only”)

A common error when using exFAT cards on older versions of MIUI.

• 🔄 Reformat the map into FAT32 (volume ≤32GB).
• 📱 Update. MIUI Up to the latest version (new firmware better support for exFAT).
• 🛠️ Check the card on another device – it may be physically damaged.

💡

If the card is in read-only mode but physically good, try disabling USB Debugging in Settings → About Phone → MIUI version (7 times tap, then return to Additional → For developers). Sometimes this resets the access rights.

7.Alternative methods: cloud services and third-party applications

If standard methods don’t work, you can use cloud storage or third-party file managers with extended rights.

Option 1: Cloud services (Google Drive, Mi Cloud, Yandex Drive)

Algorithm:

1. Upload files from your phone to the cloud (for example, through the Google Photos app or Mi Cloud).
2. On PC, download files from the cloud to SD-card (inserted in the card reader).
3. Put the card back on the phone.

Plus: doesn't require a phone to connect to a PC. Minus: Depends on the speed of the Internet.

Option 2: File Managers with root access

Apps like this FX File Explorer or Solid Explorer can get extended access rights SD-For this purpose:

1. Install the manager from Google Play.
2. In the application settings, enable Root access (superuser rights are required).
3. Copy files through the manager interface.

⚠️ Note: Using root rights voids Xiaomi’s warranty and can cause system instability. Use this method only if other methods have not helped.
