How to transfer data to SD-Xiaomi map: The full guide

Xiaomi, Redmi and POCO smartphone owners often face a critical shortage of built-in storage, especially on budget models with 32 or 64 gigabytes. Heavy gaming installation, high-resolution photo accumulation and instant messenger cache quickly fill the available space, making the system run slower. Fortunately, many modern devices support the installation of a microSD card, which can be a salvation in such a situation.

Transferring data to an external drive frees up precious gigabytes of internal memory for MIUI or HyperOS. However, this process is not always intuitive, as Android’s security policy gradually limits direct access to external drives. In this article, we will discuss all the available ways to expand memory, from standard settings to advanced methods.

It is important to understand that not all files and programs can be moved without loss of functionality. System components must remain on the internal drive for stable operation, while media files and some games feel great on the internal disk. SD-Let's look at the preparatory stage, which is the foundation for successful data transfer.

Preparation of a memory card and smartphone

Before you start transferring files, you need to make sure your drive is properly formatted and formatted.Write and read speed directly affects the speed of the phone, so using an old or slow card can lead to interface freezes. It is recommended to use Class 10 or higher cards marked as UHS-I or U3.

Insert the card into the slot of the combined tray (often it is shared with the second one). SIM-Android will offer to format the drive, and here it is important to choose the right mode of operation. You can use the card as a portable storage for photos and music or try to expand internal memory, although the latter option is on new versions. MIUI often.

⚠️ Note: Formatting completely removes all data from the card. If it has important files, be sure to copy them to your computer before starting the procedure.

Once formatted, the system will assign a new file system optimized for mobile devices to the drive, a process that can take several minutes to avoid touching the device, and make sure that the battery is at least 30-40% to avoid interruption due to discharge.

Setting up SD-maps as internal storage

One of the most desirable features for users is the ability to make a memory card part of the system partition, in which case applications and their data will be installed directly on the external drive, freeing up space inside. Unfortunately, in the MIUI shell, this feature is often hidden by developers, but on some versions of Android it is available through the standard menu.

To check availability, go to the storage settings, and if the option is active, the system will suggest moving the data and using the card as internal memory, which will turn the external drive into an encrypted partition that will not be read on other devices without special unlocking, which provides better integration, but reduces card mobility.

If the standard path doesn't work, you can try activating the hidden developer menu by clicking on the build number in the About section several times, and then looking for Forced Application Portability in the advanced settings, but even this method doesn't guarantee success on all Redmi and POCO models.

• 📱 Go to Settings. → About the phone and press 7 times on the version MIUI.
• ⚙️ Open the Advanced Settings → For developers.
• 💾 Find the item "By default, install applications on an external drive».
• 🔄 Restart the device and try installing a new app.

Transfer of photos and videos through the Gallery

The easiest and most efficient way to free up space is to transfer media files. The smartphone camera defaults to storing images in internal memory, but this path can be changed, and existing photos and videos can be moved to a map en masse without loss of quality or metadata.

Open the standard Gallery or Explorer app. Select the required albums or individual files, click More or three dots in the corner of the screen. In the drop-down menu, select Move to or Copy, and then specify the target folder to the screen. SD-For video files, this is the perfect method, because they take up the most space.

⚠️ Note: When moving large amounts of data (more than 10 GB), the process can take considerable time.Do not remove the card or turn off the phone until the operation is complete, so as not to damage the file system.

You can automate this process through the settings of the camera itself. Go to the shooting settings and find the "Save to the camera" switch. SD-Once activated, all new images will be immediately fed to an external drive, eliminating the need for manual sorting in the future, which is especially useful for those who shoot a lot of video in the future. 4K.

💡

Use the file manager to create a separate folder "Archive" on the SD-Sort old photos once a month so you don’t mix them with new ones.

Moving applications and cache

The question of how to transfer the applications themselves to a memory card remains one of the most difficult in the Android ecosystem. Since version 6.0, Google has limited this ability to only allow the transfer of programs whose developers explicitly authorized it in the application manifesto.

You can check for portability through the application management menu. Go to the settings, find a list of installed programs and select the one you want. SD-The card is active (not grey), you can safely move the program. If the button is missing or inactive, you can't do it with standard means.

For advanced users, there is the possibility of transferring the cache of heavy games (files) OBB) To do this, you need to find a folder through the file manager. Android/obb in the internal storage, copy the folder with the game and paste it in a similar directory on the SD-However, modern versions of Android can ignore these files if they are not in a strictly defined system path.

Use of cloud services and cleaning

If physical data porting to a map is not possible due to system limitations, it is worth considering alternative options for freeing up space. Cloud storage, such as Google Photos, Yandex.Disk or the proprietary Mi Cloud, allows you to store media files remotely. This does not require a memory card, but depends on the speed of the Internet connection.

Regularly cleaning the cache of messengers such as Telegram and WhatsApp can free up gigabytes of space. These apps tend to accumulate watched videos and images that are often not needed by the user after watching. Each messenger has a “Clear Cache” feature in its settings, which is safe for personal correspondence.

Also worth noting is the Cleanup feature in Xiaomi's standard Security app, which automatically finds temporary files, remnants of deleted apps and advertising debris. SD-The card will ensure stable operation of the smartphone.

Frequent problems and their solution

During operation, users may experience card read errors or slow applications migrated to an external drive. Often the problem lies in the incompatibility of the file system or the low speed class of the card itself. If the phone stops seeing the drive, try to remove it, wipe the contacts and paste again.

Sometimes the system may suggest that you format the card again, claiming that it is corrupt. Before agreeing, check the drive on your computer using the SD Formatter utility. If errors are not found, the problem may be a software failure of MIUI, which is solved by restarting or updating the system.

⚠️ Note: If the memory card is slow, applications may crash or freeze when you start, in which case it is better to return them to internal memory, and leave only photos and music on the map.

In rare cases, after flashing or resetting settings, the data on the map may become inaccessible if encryption was used. Always store important data in multiple copies. Encrypted SD-A card tied to one particular phone won’t work on another device without full formatting.
