How to transfer files from memory card to Xiaomi phone: all working methods

Why Files Aren't Copyed From MicroSD to Xiaomi and How to Fix It

Shifting data from Xiaomi’s memory card to its internal memory seems like a simple task — as long as the system does not issue a “failed to copy” error or files disappear after moving. The problem often lies in incorrect access settings, outdated MIUI firmware or physical damage to the media. For example, Redmi Note 12 and POCO X5 smartphones block the recording of external drives for some applications by default, and MIUI 14 changed the algorithm for working with the exFAT file system.

Another common situation is that you try to transfer photos from a card to a phone, but instead of copying files, they are automatically duplicated into the Mi Cloud, taking up space in both internal memory and microSD. Or vice versa, the system suggests "free up space", but after moving the files disappear. In this article, we will analyze the unique nuances for Xiaomi, from unlocking access rights to manually mounting the card via ADB.

Before you start porting, check two key points: 1) The memory card is formatted in FAT32 or exFAT (NTFS is not supported by most Xiaomi smartphones). 2 The phone settings enable file access for the Files app (Settings → Apps → Permissions → Storage).

If at least one of the conditions is not met, the methods below may not work.

Method 1: Standard copying through the Files application

The most obvious method is to use the built-in MIUI file manager. It is suitable for most models, from Redmi 10A to Xiaomi 14 Ultra, but has limitations: you can not move files larger than 4 GB on FAT32 and there may be errors when working with large folders (1000+ files).

Instructions:

1. Open the Files app (the folder icon on the desktop).
2. Go to the "Device" section» → «SD-map».
3. Select files or folders (long press → ticks).
4. Click Copy (or Cut if you want to delete the originals).
5. Return to “Inner Memory”, select the destination folder (such as DCIM/Camera for a photo) and click “Insert”.

If the "Insert" button is inactive:

• 🔹 Check if there is enough space in the internal memory (minimum reserve is 10% of the volume).
• 🔹 Try to copy files one by one – sometimes MIUI block out batch processing.
• 🔹 Reboot the phone: in MIUI 13/14 There are glitches with mounting the card after sleep.

Method 2: Transfer over a computer (Windows/macOS/Linux)

If your phone refuses to copy files on its own, connect it to a PC, a method that is more reliable because it bypasses the limitations of MIUI on external media. Importantly, use the original cable - cheap analogues can not transfer data (only charging).

Step-by-step instructions for Windows:

1. Connect Xiaomi to your computer via USB (select File Transfer mode in the notification curtain).
2. Open This Computer – Two discs should appear: the phone’s internal memory and SD-map.
3. Copy files from the card (D:\ or E:\) to the phone folder (Xiaomi\Internal Storage).
4. Wait until the device is completed and safely remove it.

For macOS/Linux:

• 🍎 Install Android File Transfer (official software from Google).
• 🐧 In Linux, mount your device via gvfs or mtp-tools (sudo apt install mtp-tools may be required).

💡

If your computer can't see the memory card, try removing it from your phone and inserting it directly into the card reader. Sometimes the microSD contacts in the Xiaomi slot oxidize, especially after moisture hits.

⚠️ Attention: Don't pull out USB-cable while copying! MIUI This can damage the file system of the map, and it has to be formatted. If the process is 100% frozen, wait 5-10 minutes, sometimes the system indexes changes for a long time.

Method 3: Use OTG-direct copy adapter

If you have OTG-cable USB-C → USB-A), You can plug the card reader directly into your phone and transfer files without a computer, and this works even with older models like the Redmi. 5A, where USB-The port only supports USB 2.0.

What you need:

• 🔌 OTG-adapter (stands) ~200–500 ₽).
• 💾 MicroSD cardholder (or adapter) SD → USB).
• 📱 Supported phone OTG (Check in the settings → The phone. → Specifications).

How to copy:

1. Insert the memory card into the card reader, connect it to the phone via OTG.
2. Open the Files» → «USB-drive" (will appear as a removable disk).
3. Select files, click Copy and paste them into internal memory.

Method 4: Transfer over cloud services (Google Drive, Mi Cloud)

If physical methods don’t work (for example, a broken card slot), upload files to the cloud and then download them to your phone, the downside of the method is the speed limit (especially on mobile Internet) and the risk of loss of quality when compressed (relevant for 4K video).

Instructions for Google Drive:

1. Install Google Drive on your phone.
2. Open the Files app, highlight the data you need on the map and click Share → Save to Drive.
3. After downloading, go to Drive, select files and click Download (they will be saved to internal memory).

For Mi Cloud (only for Xiaomi accounts):

• 🔗 Enable synchronization in Settings → Xiaomi account → Mi Cloud → gallery.
• 📁 Photos from the card will automatically upload to the cloud and then sync with internal memory.

⚠️ Warning: When downloading to Mi Cloud, videos longer than 10 minutes are compressed to resolution 720p, even if the original 4K. To avoid quality loss, use Google Drive or physical transfer techniques.

Method 5: ADB-Teams for experienced users

If standard methods don’t work and files are critically important to migrate (such as.bak backups or system logs), use Android Debug Bridge (ADB), which requires enabling USB debugging and basic command line knowledge.

Step-by-step:

1. Turn on Developer Mode: Settings → About Phone → MIUI version (click 7 times).
2. Activate USB Debugging in Settings → Additional → For developers.
3. Connect your phone to your PC and install ADB Tools.
4. Open the command line and type in: Adb devices (your device should appear).
5. Copy files with the command: adb pull /storage/XXXX-XXXX/DCIM/ /sdcard/DCIM/ (substitute XXXX-XXXX on ID You can find it by the command adb shell ls. /storage).

Advantages of the method:

• 🔧 It works even if the card is not visible in MIUI.
• 📥 You can copy system files (for example, /data/data backup).

Solving errors when transferring files

If files are not copied or disappear after moving, check these points:

If the memory card is damaged:

• 🛠️ Connect it to your PC and check for errors through chkdsk /f X: (where X is the letter of the disk).
• 🔄 If files are critical, use recovery software (Recuva, PhotoRec).

💡

If Xiaomi doesn’t see the memory card after transferring files, try restarting the phone with the microSD removed and then inserting it back in, which solves the mounting problem in 30% of cases.
