Xiaomi smartphone owners know that modern apps and games occupy a huge amount of space, but photos and videos are often the main reason for the lack of gigabytes. When the hated notification of space shortage appears on the screen, and you can not take a new picture, the question arises about optimizing storage. Moving media to an external drive is the most rational solution to free precious internal memory without removing important points.
MIUI and the newer HyperOS provide users with several ways to manage files, but not all of them are obvious at first glance. Unlike some competitors, Xiaomi allows you to flexibly configure save paths, but requires care when you first set up. In this article, we will discuss in detail all the current methods of data transfer, from standard tools to advanced file system techniques.
Preparation of a memory card and diagnostics of the device
Before you start moving files, make sure your drive is ready to work and compatible with the device.A poor or incorrectly formatted card can lead to data loss or serious loss of recording speed, which is especially critical when shooting high-resolution video.Make sure you use Class 10 or higher cards, as older drives may simply not be able to cope with the flow of data of a modern camera.
Insert the card into the slot and wait for the system to notify. If the automatic setup does not occur, you will need to format the drive through the phone settings. Note that formatting completely destroys all data on the media, so pre-copy important files to the computer if they are already there.
⚠️ Note: When formatting the card as "Adoptable Storage", it is encrypted and no longer read on other devices without reset. For simple photo storage, select Portable Storage mode».
You can check the status and characteristics of the connected drive in the settings menu. The path usually looks like: Settings → About Phone → Storage. This shows the total volume, occupied space and speed of the disk. If the system writes about errors or low speed, it is possible that the card is corrupted or is a fake, which is often found in the electronics market.
Using a full-time Explorer to move
The most reliable and versatile way to transfer existing images is to use the built-in File Manager application, which is pre-installed on all Xiaomi smartphones and has enough functionality for basic file operations without the need to install third-party software.
To start, open the app and go to Images or manually find the DCIM → Camera folder where the default images are saved. Highlight the desired photos with a long press or select all files through the control menu. After that, click on Move or Copy in the bottom action bar.
☑️ Pre-transfer check
The system will suggest you choose a destination path. Navigating the Android file system may not be obvious to a beginner. You need to select a memory card (usually denoted as sdcard1 or the name of the card brand), create a new folder there, such as Photo Archive, and confirm the operation. The copying process will take time depending on the amount of data and the speed of the card class.
It is important to understand the difference between moving and copying. When moving, the originals are deleted from the internal memory immediately after a successful recording, freeing up space, while copying creates a duplicate by taking up space in both sections, which requires subsequent manual removal of the originals to save space.
Set up automatic saving in the Chamber
To avoid manually transferring photos in the future, it is advisable to change the settings of the camera itself, which will allow you to save all new pictures and videos immediately to the external drive, leaving internal memory free for the system and application cache.
Open the Camera app and click on the menu icon (three bars) in the top right corner. In the list that opens, select Settings. Scroll down to the Save section. Here's the Save to Save to Settings to the list. SD-Activate it, and the system will redirect the data stream.
However, technical limitations should be considered: If you shoot video in 4K resolution or use 60/120 FPS, the phone can force the material to be stored in internal memory, because the write speed on many budget memory cards is not enough to process this data stream in real time, and the frame can simply “lost” or the video will twitch.
💡
Use cards with a recording speed of at least 30MB/s (V30 marking) to shoot 4K video to avoid skipping frames.
Also keep in mind that some third-party apps, such as Instagram or Snapchat, may ignore system settings and continue to write cache and temporary files into internal memory.This is normal for apps to work, but requires periodic cache cleaning.
Working with folders of messengers and social networks
One of the main problems of Xiaomi owners is the proliferation of folders from instant messengers. Telegram, WhatsApp and Viber store thousands of images received, which are often duplicated in the gallery and take up space. You can transfer them to a memory card, but care is required not to disrupt the application.
Unlike the Camera system folder, the structure of messenger folders is more complex. 11 and above, access to some system folders is limited, but through Xiaomi Explorer you can still move the contents of folders Android/media Or root directories of applications. WhatsApp/Media/WhatsApp Images or Telegram/Telegram Images.
Select the content and move it to a memory card in a specially created folder structure. To prevent new files from filling the internal memory again, go to the settings of the messenger itself. On WhatsApp this is the Settings section → Chats → Backup of chats (for photo settings may vary depending on the version), where you can try to change the path, although the functionality is greatly reduced compared to iOS.
⚠️ Note: Do not move the system files of databases (files with the extension.db or.sqlite) located in the folders of messengers, mp4, gif. Deletion or relocation of databases will result in loss of correspondence.
To automate the process of cleaning garbage from messengers, you can use the built-in utility "Security app" (Security app), which can find large files and duplicates, suggesting that they be deleted, but the function of transferring them to the Internet is not limited to the Internet. SD-The card it usually fails to execute, requiring manual intervention through the Conductor.
Comparison of Storage Methods: Efficiency Analysis
The choice of memory management strategy depends on your smartphone usage habits. Below is a table comparing the basic approaches to storing photos on Xiaomi devices so you can choose the best one for yourself.
| Parameter | Internal Memory (UFS) | SD-map (Portative) | Cloud storage |
|---|---|---|---|
| Read/write speed | High (up to 1000 MB/s) | Medium/Low (10-90 MB/s) | Depends on the network. |
| Data reliability | Tall. | Medium (risk of loss in case of breakdown) | Tall. |
| Access from other devices | Only through cable/network | You need an adapter or a phone. | From anywhere in the world. |
| Impact on the system | Delaying filling | Minimum | Traffic consumption |
As can be seen from the table, the internal memory of the smartphone based on UFS It's much faster than any memory card, which is why the system and the applications work faster when there's space on the internal drive. SD-map, you sacrifice the speed of access to the archive (the photos in the gallery can open a little longer), but you win in the stability of the OS.
Cloud services like Google Photos or Xiaomi Cloud are a great addition, but they don’t always replace physical media because of their dependence on the Internet and data plans. A combined approach where current photos are stored in the cloud for quick access and a year’s worth of archives on a memory card is often the best solution.
Solution: Hidden files and access errors
Sometimes users are faced with a situation where, after transferring photos disappear from the gallery or appear as corrupted. Often this is due to the absence of the.nomedia marker file or, conversely, its presence in the new folder. This hidden file instructs the Android media scanner to ignore the contents of the folder.
If your photos are not visible after transfer, check the settings for displaying hidden files in Explorer. Path: Explorer settings → Hidden files → Show. If you see a.nomedia file in the photo folder on the memory card, delete it. After that, you may need to reboot the device to re-index media files.
Why can't the phone see the memory card?
Another common problem is the "Not enough rights" error when you try to move, which is an Android security mechanism that restricts applications from accessing system folders, in which case you'd better use a computer: connect your phone over USB in File Transfer (MTP) mode and drag the folders directly through the Windows or macOS interface.
Remember to check the integrity of the memory card regularly, and it is recommended to connect the card to your computer every six months and run an error check, since the FAT32 or exFAT file system used on the cards is more prone to logical failures than the internal storage file system.
