How to transfer files from your phone to Xiaomi memory card: all the ways to MIUI 12-14

Transferring files from Xiaomi’s internal memory to a microSD card is a challenge that every user will eventually face.

1.Preparation: Memory card check and storage settings

Before you transfer files, make sure your microSD card is device compatible and formatted correctly. Xiaomi supports cards up to 1TB (like the SanDisk Ultra 512GB A2), but there are nuances:

• 🔹 File system format: for cards up to 32 GB — FAT32, ExFAT (recommended). NTFS unsupported!
• 🔹 Speed class: for recording video 4K class A2 or U3 (Minimum recording speed of 30 MB/s).
• 🔹 Hybrid Slot: If you have a model with two SIM-cards (e.g. Redmi) 10C), The memory card can only be inserted in place of the second SIM.

To check the current map format:

1. Open the Settings → Memory.
2. Tap your name on it. SD-maps (e.g. SanDisk) 128GB).
3. In the Information section, look at the File System line.

2. Method 1: Automatically save new files to SD-map

The easiest way to avoid manual transfer is to set up MIUI so that new photos, videos and downloads are immediately saved to the memory card.

2. Select a Retention Site → Memory map.
3. Create a folder (like Downloads) or select an existing one.

⚠️ Note: Some models (e.g. Xiaomi) 12T) while keeping the photo SD-map-off function AI-To get it back, you can manually transfer the files after you've taken the shot.

Method 2: Manual transfer through MIUI Conductor

If you need to transfer existing files (e.g. old photos or documents), use the built-in Explorer, which is suitable for all file types except for application data (you can only transfer them via App2SD, see Method 4).

Step-by-step:

1. Open the Explorer app (the folder icon on the home screen).
2. Go to Device (Inner Memory) and find a folder with files (for example, DCIM → Camera for a photo).

Method 3: Transfer application data to SD-map (App2SD)

Many users find that even after transferring photos and videos, internal memory is filled due to cache and application data. MIUI has an App2SD feature, but it does not work with all programs and has limitations:

• 📱 Only apps that allow portability (e.g. Spotify, Netflix) are supported).

1. Install Android File Transfer (official software from Google).
2. Connect your phone and allow access to files.
3. Drag the files into the folder SD-maps through Finder.

💡

When copying through a PC, the speed is limited by the USB interface. On Xiaomi with USB 3.1 (for example, Mi 11 Ultra), it reaches 500 MB / s, on budget models (Redmi 9A) - up to 40 MB / s.

If the computer can't see SD-map:

1. Check that the card is inserted to the end (on hybrid slot models, a reboot is sometimes required).
2. B Settings → Memory on the phone tap on the map and select Connect how USB-accumulator.
3. Update your MTP drivers on your PC through Device Manager.

7. Problem Solving: What to Do If Files Are Not Portable

Sometimes there are errors when transferring files, and we will consider the cases and ways to solve them:

• 🚫 "Not enough space": Check the real size of the map through Settings → Sometimes Xiaomi reserves up to 10% of the space for system needs.
• ❌ "File too big: The map is formatted in FAT32 (4GB file, reformat it to exFAT.
• 🔒 "No access": Write protection is on the map. Check the physical switch on the adapter (if any).
• 🐢 "Copying is “hung”: Turn off battery optimization for Explorer in Settings → Battery → Optimizing the battery.

If the memory card is not determined:

1. Remove it and wipe the contacts with a dry wipe (on Redmi Note 11 models, the contacts are often oxidized).
2. Try inserting the card into another phone or card reader.
