Transfer data to the memory card Xiaomi Redmi Note 8: the full guide

Owners of Xiaomi Redmi Note 8 often face a shortage of free space, especially if the device is used to shoot high-resolution photos or install heavy games. The built-in storage volume quickly fills up, and the system begins to warn about the critical state of memory. The solution to this problem is the use of a microSD memory card, which allows you to expand the capabilities of the device without losing important files.

The process of transferring information may seem complicated only at first glance. Modern versions of the MIUI shell offer convenient tools for managing files, but there are hidden nuances that you should know about in advance. In this article, we will discuss in detail how to properly prepare the drive, move the media and even try to migrate the applications themselves to maximize space.

It is important to understand that not all data can be moved by standard means of the system. Some system files and cache of certain programs must remain in internal storage for the correct operation of the operating system. However, a competent allocation of resources will allow you to forget about the messages "Memory is full" and comfortable using your smartphone.

Preparation of a memory card and smartphone

Before you start porting, you need to make sure your drive is working and formatted in the right file system. For Android-based devices, the best choice is the exFAT or FAT32 file system, which provides maximum compatibility. If the card has been previously used on another device, it is better to conduct a full formatting to eliminate read errors.

Insert the microSD card into the slot located in the tray for SIM-Use a special paper clip from the kit to remove the tray. Pay attention to the correct orientation of the contacts - they must match the circuit applied to the tray. Once installed, the system must automatically detect the new drive and prompt it to configure it.

⚠️ Note: Formatting a memory card completely removes all the data on it. If there are important files on the drive, be sure to copy them to your computer before installing them on your smartphone.

To check the speed and absence of broken sectors, you can use built-in diagnostic tools or third-party utilities. A high-quality map of the UHS-I class or higher will ensure fast video recording and loading of heavy resources. Cheap drives can cause “brakes” of the interface when working with files.

💡

Buy memory cards only from official dealers or from large chains, as the market is full of fakes that fail after a month of use.

Transfer of photos and videos through the Gallery

The most voluminous content that takes up space in a smartphone is media. The Redmi Note 8 captures high-resolution video, and one minute of video can weigh hundreds of megabytes. Moving that data to an external drive is the first step to freeing up space. You can do it with regular means without installing additional software.

Open the Gallery app and go to Camera or Screenshots. Select the photos and videos you need with a long press. In the bottom menu that appears, select "More" or the three-dot icon, and then click Move. The system will suggest select the destination where you want to specify your memory card.

• 📸 Select all the photos in a month to transfer them in one operation.
• 🎥 Video files 4K It is better to move several pieces in order not to overload the clipboard.
• 📁 Create a separate folder on the map «Archive_2026» orderly.

Once the process is complete, the originals will be deleted from the internal memory, and only the file links will remain in the gallery. The process will be transparent to the user, you will continue to see all your pictures in the general list, but physically they now occupy space on the external medium, which was required.

Use of a conductor for mass transfer

For more flexible file management, including documents, downloads and messenger cache, system Explorer is better. This tool allows you to see the full structure of folders and move data where you can not get through the Gallery. The standard application is called Files or File Manager and has a yellow folder icon.

In the conductor interface, select "Internal Drive." Find folders that take up a lot of space. Most of the time, it's called "Internal Drive." DCIM (photo), MIUI (Screenshots and voice recorder, Download (downloads from the browser). Select the directories you want, click Copy or Cut, then go to the section «SD-map and select "Insert».

When working with large amounts of data, copy speeds can vary. Do not interrupt the process or turn off the smartphone screen if possible to avoid damaging the file structure. If the copying has stalled, it is better to wait for completion, even if it takes time.

Transfer applications to memory card

The issue of transferring the applications themselves to the memory card in modern versions of Android is ambiguous. Google has limited this opportunity to improve the stability of the system, since external cards work slower than internal memory. However, in the shell MIUI for Xiaomi Redmi Note 8 there are ways to circumvent the restrictions for individual programs.

Go to Settings. → Annexes → All applications. Select the program you want to move (for example, a heavy game or a navigator). If the developer has authorized the transfer, the "Move to" button is used. SD-If the button is grey or missing, it means that the application is tightly tied to the internal storage.

• 📲 Move only those applications that support this feature.
• ⚙️ After the transfer, the application shortcut remains on the desktop.
• 🚀 The performance of the application may decrease slightly when you start.

There is also a Memory Combination method, where the system perceives the card as part of internal storage. However, for the Redmi Note 8, this method often leads to unstable operation and data loss when crashes.

⚠️ Note: When transferring applications, their work may become less stable; critical programs, such as banking applications or instant messengers, are better left in internal memory.

Setup of the camera to record SD-map

So you can set your smartphone camera to automatically record all new photos and videos right on your memory card, and that's the most efficient way to keep order, and in the standard Camera app, this feature is enabled in the settings.

Open the Camera app, click on the three bars in the upper right corner and select Settings. SD-Map" (or "Save Priority") and activate the switch. From now on, all new images will automatically be taken to the external drive.

It is worth noting that ultra-high resolution or slow motion modes can ignore this setting and write data to internal memory due to the recording speed requirements, in which case the system will independently determine the optimal location to save so as not to lose the frame.

💡

Automatic writing to a memory card is the best way to prevent internal storage from overflowing in the future.

Cleaning cache and temporary files

Even after transferring files, memory can be refilled due to cache growth. Social networks, browsers and streaming services accumulate gigabytes of temporary data, and regular cleaning of these files will help keep the system on track.

Use the built-in Security app (green shield). Run the scan and click "Clean." You can also manually go to the storage settings and clear the cache of specific heavy applications like Telegram or YouTube. This is secure and will not delete your personal correspondence.

For advanced users, there is a developer mode where you can see detailed memory usage statistics. Pathway: Settings → About Phone → 7 times click on the MIUI Version. Then you can find additional analysis tools in the Developer Menu, but be careful when changing system settings.
