Transfer files to SD card on Xiaomi: the complete guide

Modern smartphones line Xiaomi and Redmi offer impressive specs, but even 128 or 256 GB of internal memory can run out at the wrong time, 4K-Video and heavy games quickly fill the available space, making the system work slower, and at this point comes the help of a microSD card, which allows you to significantly expand the storage without losing important data.

Many users mistakenly believe that it is enough to simply insert the drive to automatically start saving files there. In practice, MIUI requires manually configuring or transferring existing data to effectively use external storage. In this article, we will discuss in detail all available methods for freeing internal memory, including hidden developer functions and working with system files.

Do not ignore memory overflow, as this can lead to unstable operation of the Android Operating System. SD-This card will extend the life of your device, so let's look at how to organize the file structure on your gadget.

Preparation of memory card and diagnostics of storage

Before you start taking active data transfer actions, you need to make sure that the memory card itself is healthy and that it is correctly displayed in the system. Put a microSD in the smartphone tray using a special key to extract, and wait for the notification of the connection of the new drive. If the system offers to format the card, agree, but pre-save important data on the computer, because formatting will delete all the content.

To get a good sense of the situation, go to the storage settings, and here you will see detailed statistics on how much space apps, images, videos, and system files take up. Internal memory is often occupied by a messenger cache that can be safely cleared by freeing up gigabytes of space before transferring heavy media files.

Pay attention to your card's speed class. High-resolution video recording and application installation require high read and write speeds. If the card is too slow, the system may alert you to low performance, and video shooting may be interrupted.

⚠️ Warning: Buy memory cards only from trusted sellers. The market is oversaturated with fakes that show the full volume in the system, but actually record data in a loop, irretrievably losing information.

Basic transfer of media files through a standard conductor

The easiest and safest way to move photos and videos is to use the built-in Explorer or Files app. This method does not require root rights and is suitable for all Xiaomi, Redmi and POCO models. Open the app and select a category, such as Images or Video, to see all files on the device.

Select files with a long press. To select a group of files, it is convenient to use the "Select All" function or to mark specific folders. Click on the menu (three dots) and select "Move" or "Copy". In the navigation window that opens, specify the path to your destination. SD-Create a new folder or select an existing one to save.

• 📁 DCIM — A standard folder for photos from the camera, it can be transferred whole.
• 🎵 Music – here are stored downloaded tracks and audio recordings.
• 📹 Movies – folder for downloaded movies and TV series.
• 📄 Documents – a place for storing working documents and PDF.

The process of copying large amounts of data can take time: Do not turn off the screen or turn off the Explorer app during the operation to avoid write errors. Once completed, check the files in a new location by opening several of them.

💡

When you transfer thousands of small photos, it can be slow. 500-1000 So the system doesn't freeze.

Configure saving photos and videos immediately to the map

To avoid manually transferring files in the future, you can set your smartphone camera to automatically save new images immediately to an external drive, especially for those who are high-resolution mobile photographers. Open the Camera app and go to settings by clicking on the three bars in the upper right corner.

In the settings menu, find the item "Save to" SD-You can use a map or something like that, and you can activate the switch, and all the new images and videos will be sent by default to the external storage, but you have to remember that when you shoot video in the video, you can use the video in the computer. 4K or when using high frame rate modes, the system may ignore this setting if the card write speed is insufficient.

It’s also worth checking the voice recorder and screenshot settings, and in some versions of MIUI, these apps have their own save path settings that need to be changed separately from the main camera.

Transfer of installed applications to SD card

The issue of transferring applications to SD-Map in modern versions of Android and shell MIUI Google has limited this capability for the sake of security and stability of the system, but some applications allow you to change the path to data in your internal settings. → Annexes → All applications, select the desired application (for example, navigator or messenger) and check for the “Change” button in the storage section.

If the button is active, you can move the cache and application data to an external drive, which is often available for heavy gaming and offline maps, but system applications and mission-critical services cannot be moved, as they must be loaded with the operating system.

There is a method of forced transfer through the developer menu, but it works unstable. To activate it, go to Settings. → About the phone and seven times quickly click on the build number MIUI. Then, in the advanced settings, find the item "Preferred installation location" and select SD-After installing new applications, the system will suggest selecting the installation location.

⚠️ Note: The applications that are ported in this way may be slower and stop running if you remove the memory card.

Use of the card as an internal storage (Adoptable Storage)

A function that combines internal memory and SD-map into a single space, in MIUI It's hidden by default. It's called Adoptable Storage, and it requires a superuser's rights or a use of it to activate it. ADB-Without root rights, this method is only available on some global firmware versions through a hidden engineering menu.

If you do this, remember that the card will be formatted into a special format that is not readable on other devices, and it will become part of the system. To activate through ADB, you need to connect the phone to your PC, enable debugging over USB, and enter a command to force you to create a partition for applications on an external medium.

adb shell sm partition fuse-blk:179,64 mixed 50

Where 179.64 is your card ID (you need to know it through the adb shell sm list-disks command) and 50 is the percentage of memory allocated to applications, this method is only suitable for advanced users who understand the risks of data loss.

• 🚀 Speed – the card must be of class UHS-I higher.
• 🔒 Encryption – data on the card will be encrypted with phone keys.
• ⚠️ Risk – card failure can “put” the system.

Problems and their solution when working with SD card

Even if you do everything right, users can encounter errors "SD-The card is damaged" or "Formatting required. "First of all, try to extract the card, erase the contacts with a pin and paste again. If the problem persists, check the card on your computer using the utility. SD Formatter.

Another common problem is that files stop being read after a system update, which is due to a change in access rights in new versions of Android, which may require reconfiguration of paths in applications or rechecking permissions in the Settings menu → Apps → Permissions → Files and media.

💡

If the phone is constantly losing the card, it may be that the contacts in the slot have oxidized or the card itself has a physical defect of the controller.

Also worth mentioning is overheating, when you're actively recording videos or when you're running heavy applications with a computer. SD-The area around the slot can get hot, which is normal for high-speed recording, but if the heating is critical, take a break.
