Xiaomi smartphone owners are well aware that the device's internal memory is filling up rapidly, 4K-Video and screenshots of correspondence take up gigabytes, which inevitably leads to a lack of free space, when the internal storage is crowded, the system starts to work slower, and new images become impossible to create, which causes irritation to the user.
The most efficient and budget-friendly solution is to use a microSD memory card. However, the standard logic of Android and the MIUI or HyperOS shell does not always allow you to simply drag and drop files like on a computer. Often users have to face access restrictions or get confused in the system folders created for data security.
In this article, we will discuss in detail all the current ways to transfer the media library to an external drive. You will learn about the intricacies of the built-in Explorer, methods of forced change of the path of saving in the camera and ways to bypass the restrictions of Android 11-14. Proper file management will allow you to free up precious space and forget about the constant notifications "Memory is filled."
Preparation of memory card and compatibility check
Before you start manipulating files, you need to make sure that your drive is ready for active work. Not every card purchased in the store is suitable for recording high-resolution video or fast application. The most important parameter is the speed class, which indicates the minimum speed of writing data. For modern Xiaomi smartphones, cards labeled Class 10, U3 or V30 will be the best choice, since they provide stable operation without jerks during shooting.
After physically installing the card in the tray SIM-Android usually recognizes a new device immediately, but if the card has been previously used on another device or computer, it may need to be formatted. Note that formatting will completely destroy all data, so if there are important files on the map, they must be pre-copyed on the PC.
The formatting process is best done by the smartphone itself to ensure maximum file system compatibility. Go to settings, select About Phone, then Storage, and find your card in the list. When you click on it, you will see the formatting option. Once this procedure is completed, the system will create the necessary folder structure, and the drive will be ready to record photos.
💡
Use memory cards up to 256GB for maximum stability. 512GB and 1TB cards may not work properly on older Xiaomi models or require manual formatting in exFAT.
Standard Transfer through Integrated Conductor
The easiest and safest way to move existing photos is to use the File Manager app, which is pre-installed on all devices in the brand, which has access to all memory areas visible to the user and allows you to copy or cut files. Open the application and select the Images category or go to internal memory to manually search for folders.
You'll need to find a folder that stores the images by default. In Android, it's usually a directory. DCIM/Camera. When you select the desired files or entire folders, click the "Copy" or "Slice" button in the lower menu"SD-Create a new folder there (for example, "Photos"); 2026") and press "Insert".
It's important to understand the difference between copying and moving. If you choose Copy, the originals will remain in internal memory, taking up space until you manually delete them. Cut mode moves files immediately, freeing up space instantly after the operation is completed. Be careful when interrupting the process: if you extract the card while you write, files can get corrupted.
☑️ Algorithm of file transfer
It's worth noting that newer versions of the HyperOS shell may have slightly different interfaces, but the logic remains the same: If the standard application doesn't see the memory card, check if it's correctly defined in the storage settings, and sometimes it helps to reboot the device after installing the drive.
Set up automatic photo saving on SD-map
Many users want new images to be immediately transferred to the external drive, bypassing internal memory. Unfortunately, in modern versions of Android (starting with version 11), Google has limited the ability to fully migrate save paths for applications due to security and system stability.
To check this feature, open the Camera app and click on the three horizontal bars in the upper right corner to enter the settings. SD-If the switch is active and pressable, just activate it. Now all new photos and videos will be recorded by default to an external medium.
Why is the SD save not in the settings?
If the standard camera does not allow you to change the path, you can use third-party applications from Google Play, such as Open Camera. In the settings of such programs in the section "Storage settings", you can clearly specify the path to the memory card, which will bypass the system restrictions of stock software and record immediately to the external volume.
It should be noted that the speed of recording on SD-The card may be lower than the internal memory of the phone, when shooting serial pictures or videos in the phone. 4K This can cause delays or interruptions in recording, so it's best to use internal storage for professional photography, and then to transfer the finished material to the map.
Working with Android folder and access restrictions
With the release of Android 11 and the implementation of the Scoped Storage policy, application access to root system folders, including Android/data and Android/obb, was significantly limited. This also affected Explorers. If you try to move photos from messengers (WhatsApp, Telegram) or social networks, you may find that the system does not allow you to copy files from these hidden directories.
To circumvent this restriction, new versions of MIUI require that Explorer be given special permissions. When you try to access an Android folder, the system will issue a pop-up warning. In this window, you click "Allow access to the folder", then select the Android folder in the system window that opens and press the blue "Allow access to the folder" button at the bottom of the screen.
💡
Without special permission to access the Android folder, you will not be able to move media files from messengers to the Internet. SD-Card via standard file manager.
If the standard Xiaomi Explorer still refuses to work with system folders, it is recommended to install a more advanced file manager, such as Total Commander or Material Files. API And they allow you to manage files in secure partitions without root rights, and they do the same thing: copy from internal memory to the corresponding folder on the back of the back. SD-map.
Also, it is worth considering that some applications may not work correctly if their cache or data is moved to a slow memory card. Photos and videos are transferred safely, but application system files should not be touched to avoid software failures.
Comparison of transfer methods and their features
To make it easier to choose the best way to manage files, we have systematized the basic methods into a spreadsheet, each with its own advantages and disadvantages depending on your goal: a one-time cleanup of the site or constant work with the archive.
| Method | Difficulty | Speed of operation | Risks. |
|---|---|---|---|
| Built-in Conductor | Low. | Tall. | Minimum |
| Third-party file manager | Medium | Tall. | Low (access rights errors) |
| Connection to PC (USB) | Medium | Very high. | No risk to OS |
| Changing the path in Camera Settings | Low. | Instant. | Possible loss of photo when card fails |
Using a computer to transfer large amounts of data (like the entire archive for a year) is often the fastest and most reliable way. USB-cable in the mode "File transfer" (MTP), copy the folder DCIM to the hard drive of the PC, then remove it from the phone and transfer it to the computer. SD-This method eliminates overheating of the smartphone and battery consumption.
However, for daily use, it is most convenient to set up automatic saving or regularly clean memory through Explorer. The choice of method depends on how often you take pictures and how much they are. For videographers shooting in 4K 60fps, using a PC or a fast card reader will be preferable to wireless methods or direct copying on the phone.
Frequent problems and their solution
When moving files, users can encounter a variety of errors, and one of the most common is the message "Not enough space," even if there are several gigabytes of free card space. This is often associated with the file system: if the card is formatted in FAT32, you can't write a file larger than 4 GB onto it. The solution is to format the card in exFAT through your phone's settings.
Another problem is that photos disappear from the gallery after they're transferred. Xiaomi Gallery scans certain folders. SD-The file file may not be visible to the gallery. To fix this, put the files in a standard folder. DCIM on the map or use the function "Hide / Show albums" in the settings of the Gallery.
What to do if your phone can’t see SD-map?
It is also a case of ported photos being displayed as “broken” or black screen, a sure sign that the memory card has a low write speed or damaged sectors, in which case you should check the drive for errors or replace it with a better-quality counterpart from a proven brand such as Samsung, SanDisk or Kingston.
💡
Regularly back up important photos to the cloud (Google Photos, Yandex.Disk) or to your computer. A memory card is a consumable that can fail at any time, unlike the phone's more reliable internal memory.
