How to transfer data from internal memory to SD-Map in Xiaomi smartphones: 5 working ways

Xiaomi’s internal memory clogs up faster than you realize: high-resolution photos, app cache, downloaded files from instant messengers and system utilities updates eat up gigabytes in a matter of weeks. POCO X5 It's 128GB of internal memory, and you're going to have to think about cleaning it up sooner or later. SD-map, but here users are waiting for pitfalls: from restrictions MIUI before the features of storage formatting.

In this article, we will analyze all the current methods of transfer – from standard system tools to hidden functions for experienced users. You will learn how to move not only media files, but also applications (yes, it is possible even without root rights!), and also why some files fundamentally refuse to move to an external drive. 10C or POCO M4 Pro, where SD-card SIM, and on the nuances of working with maps of formats FAT32, exFAT and NTFS.

We warn you that not all methods are equally effective. For example, transferring applications through Settings → Applications often crashes if the card is not formatted as internal memory. And trying to move system files manually can result in an error of "Not enough rights." But don't worry, we have tested each method on real devices (from Redmi 9A to Xiaomi 13 Ultra) and are ready to share working solutions.

1. Preparation SD-Maps: Formatting and Selection of File System

Before transferring data, you need to properly prepare yourself. SD-It's the file system that determines which files you can move to it and how they work. MIUI It supports three main formats:

• 📁 FAT32 — Compatible with all devices, but limited to files up to 4GB. Suitable for photos, music and documents.
• 📁 exFAT – removes the file size limit, ideal for video in the video 4K We recommend for cards from 64 GB.
• 📁 NTFS — It is rarely used in mobile devices, but can be useful for Windows PCs.

If you plan to port apps, the card will have to be formatted as internal memory (the Adoptable Storage feature in Android), but this method has serious drawbacks:

⚠️ Note: Formatting a card as an internal memory binds it to a particular device, and once it is extracted, the data on it will not be available even on a PC without special utilities, and this method can cause lags if the class card is not available. UHS-I slower.

To format the map:

1. Put it in. SD-card in the slot (with a hybrid slot you will have to temporarily remove the second slot) SIM).
2. Go to Settings. → Memory. → SD-map.
3. Slip on the three dots in the upper right corner and select Memory Settings.
4. Choose Format as internal (for applications) or Format as portable (for media files).

2. Transfer of media files (photos, videos, music) by standard means

The easiest way to free up memory is to move photos, videos and music. MIUI offers two options:

• 📷 Through the Gallery: Select files → More. → Move it → SD-map.
• 🎵 Through File Manager: Find folders DCIM, Download or Music → highlight files → Cut/copy → SD-map.

But there are pitfalls here:

⚠️ Note: If you are transferring photos from the folder DCIM/Camera, Some apps (like Google Photos) may stop seeing them. SD-file-card (DCIM/Camera) and transfer files there.

Automatically save new photos on SD-map:

1. Open the chamber.
2. Put it on the gear (⚙️) → Camera settings → Preservation site.
3. Choose. SD-map.

If the option is inactive, check:

• 🔹 The card is formatted as portable (not internal).
• 🔹 There is enough free space on the map (at least 10% of the volume).
• 🔹 The card is not damaged (check through Settings). → Memory. → SD-map → Verification).

💡

If photos are not displayed in the gallery after transferring, restart your smartphone or use the file manager to scan folders (Mi File Manager has the option to “Update Media Library”).

3. Transfer of applications to SD-map: restrictions and workarounds

Transfer applications to SD-Xiaomi maps are more complex than media files, and the limitations of Android and MIUI:

• 📱 Only a portion of applications support portability (usually games and heavy utilities).
• 📱 System applications (Mi Home, Security) cannot be moved.
• 📱 After the transfer, the application may run slower (depending on the class). SD-map).

To try to migrate the application:

1. Go to Settings → Applications → Application Management.
2. Select the app you want (like Facebook or PUBG Mobile).
3. Put Memory on it. → Change. → SD-map.

If the option is inactive, try these methods:

SD-The card is formatted as internal memory.|

Class of card not lower than UHS-I (U1)|

The app is not system-based and is not updated through Play Market|

In the developer settings, the option "Forced transfer to the SD" (if available)-->

⚠️ Attention: Transfer of applications to SD-A card formatted as an internal memory can cause data loss when you retrieve the card. SD-card SIM, Applications will stop working before re-inserting.

For power users, there is an alternative way to use ADB (Android Debug Bridge), which allows you to force transfer even those applications that do not support this feature by default, but the method requires a connection to a PC and knowledge of commands:

adb shell pm set-install-location 2 # forced transfer to SD


adb shell pm get-install-location # checking current location

After these commands are executed, new applications will be installed on the SD-The default card. To get it back, use it:

adb shell pm set-install-location 0

4. File Transfer over PC: When Standard Methods Fail

If the smartphone refuses to transfer files (e.g., it gives an error "File is used" or "Not enough space"), you can use the computer, which is more reliable because it allows you to bypass the limitations of MIUI.

You'll need:

• 🖥️ PC Windows/macOS/Linux.
• 🔌 Cable USB (preferably original).
• 📁 File Manager (e.g., Total Commander or Standard Explorer).

Step-by-step:

1. Connect your smartphone to your PC via USB.
2. On your smartphone, select file transfer mode (File Transfer or MTP).
3. Open the folder of internal memory on your PC (usually called Xiaomi Redmi...).
4. Copy the files you want (for example, from Download or Documents folders) to your desktop.
5. Turn off the smartphone, insert SD-card in the adapter and connect it to the PC.
6. Transfer files from the desktop to the SD-map.

⚠️ Note: Do not copy system folders (Android, MIUI, Data: This can cause smartphone malfunctions, and avoid transferring files with the.db or.odex extension.

If the PC can't see SD-map through the adapter, check it out:

• 🔹 The card is formatted in exFAT or FAT32 (NTFS It may not be readable on some devices).
• 🔹 Adapter is good (try another one).
• 🔹 There are no broken sectors on the map (check through chkdsk in Windows).

5. Automatic data transfer: default setting

To avoid manually transferring files every time, you can set up automatic saving to SD-It works for some types of data:

• 📸 Photo and video from the camera.
• 🎥 Downloads from the browser (Mi Browser, Chrome).
• 📄 Files from messengers (Telegram, WhatsApp).

How to set up:

For the camera:

1. Open the Camera app.
2. Put it on the gear (⚙️) → Settings → Preservation site.
3. Choose. SD-map.

For downloads from the browser:

1. Open Chrome or Mi Browser.
2. Go to Settings → Downloads.
3. Point the way to the folder on SD-map (e.g., map, /storage/XXXX-XXXX/Download).

For messengers:

• 📌 Telegram: Settings → Data and memory → Download folder → point the way SD-map.
• 📌 WhatsApp: Chat and media transfer is only possible through backup on Google Drive (SD-card not supported).

⚠️ Note: If you use Google Photos to back up, automatically save to SD-The map may conflict with synchronization, in which case the files will be duplicated, taking up space both there and there.

💡

Configure automatic saving to SD-The card saves time, but keep an eye out for free space: if the card is filled, new files will start to be saved to internal memory by default.

6.Data Transfer Problems and Errors: How to Solve Them

When transferring data to SD-Xiaomi users often encounter errors. Let's consider the most common and ways to fix them:

If the smartphone does not see SD-map:

1. Check if the card is inserted correctly (in hybrid slots, it should click).
2. Clean the contacts of the card with a stripe (sometimes helps with oxidation).
3. Try the card in another device (such as a camera or PC).
4. Update the MIUI firmware – older versions had bugs with exFAT support.

If, after transferring the application to SD-map it's out:

• 🔹 Move it back to your internal memory.
• 🔹 Clear the app cache in Settings → Annexes.
• 🔹 Check the card for the recording speed (minimum class — UHS-I).

7.Alternative ways to free memory without SD-map

If the transfer is SD-The card didn’t help or you don’t want to use it, there are other ways to free up your internal memory:

• ☁️ Cloud storage: Google Photos (unlimited space for compressed photos), Mi Cloud (5 GB free), Yandex Drive (10 GB).
• 🧹 Cleaning the cache: in Settings → Memory. → Cleaning can remove unnecessary files (cache, APK, duplicates).
• 🔄 Transfer to PC: regularly copy photos and videos to your computer or external hard drive.
• 🗑️ Delete Heavy Files: Use Files by Google to Find Large and Unnecessary Files.

Applications can be used to automate the process:

• 📱 Files by Google – Finds and suggests removing duplicates, temporary files and unused apps.
• 📱 SD Maid – Clears cache, empty folders and residual files after uninstalling applications.
• 📱 CCleaner – analyzes memory and offers optimal cleaning options.

⚠️ Note: When using cloud storage, disable autoloading of media files in messengers (WhatsApp, Viber), otherwise they will be duplicated in both internal memory and in the cloud.
