Xiaomi smartphone owners know how quickly internal storage fills up when you use the camera actively. Modern matrices create high-resolution images, and modes like 108 MP or RAW take hundreds of megabytes in a matter of minutes. The system limit of 64 or 128 GB is no longer an advantage and turns into a headache, requiring constant cache cleaning and deleting old applications.
Fortunately, the ecosystem MIUI And the new HyperOS provides flexible tools for managing media files. Moving photos to an external drive is not just a way to free up space, but also a way to create a backup that is independent of cloud services. SD-maps, from the initial setting to the automation of the shooting process.
Many users mistakenly believe that it is easy to insert a card, but to work properly the system needs to perform a number of settings. exFAT file system is the standard for cards with a capacity of more than 32 GB and provides better compatibility with modern versions of Android. Let's consider a step-by-step algorithm of actions that will help you forget about the shortage of space forever.
Preparation SD-maps and compatibility checks
Before you start porting data, you need to make sure your drive is properly formatted and recognized by the system. Xiaomi smartphones support microSD cards up to 1 TB or more, however, recording speed is critical. If you plan to shoot 4K video, a cheap Class 4 card will slow down and recording can be interrupted.
Put the card in the SIM card tray and wait for the system to notify you. If the card was previously used on another device, Android may suggest formatting it. Attention: formatting will completely delete all data, so save important files on the computer in advance. After formatting, the system will assign the drive a path along which new images will be stored.
You can check the status of the card through the settings menu. Go to Settings → The phone. → Storage. Here you'll see total space and, separately, status. SD-If the system offers to use the card as an internal storage, weigh all the risks: if the card breaks, access to the applications will be lost, so it is better to use portable storage mode for photos.
⚠️ Warning: Do not remove the memory card while recording a video or saving a series of pictures.This can damage the file system and lose the last photos taken.
Setup the camera to save the photo on SD-map
The most efficient way to transfer is to set up automatic saving of new images directly to the external medium. In the standard Xiaomi Camera app, this feature is hidden in the settings menu, but it works faultlessly. Open the camera app and click on the three bars in the upper right corner, then select the gear settings.
In the list you have opened, find the item “Save on” SD-map «SD-Activate the switch. From now on, all new photos and videos will be recorded along the way. /storage/emulated/0/DCIM/Camera, But physically, it doesn't require manual file movement, and it saves user time.
It is worth noting that some shooting modes may ignore this setting, such as Documents mode or specific filters sometimes save copies to internal memory for quick processing by the image processor. Regularly check the main storage capacity, even if the bulk of the files go to the map.

Manual transfer of existing photos through the Explorer
If you already have a gallery of images in your internal memory, you need to move them manually. To do this, Xiaomi uses the built-in File Manager app, which has a user-friendly interface and sorts by file types. Launch the application and select the Images category or go to the root folder of the internal storage.
Find the file. DCIM, And inside it is Camera, and it stores all your pictures, and you can either select the photos you want with a long press, or you can use the "Select All" feature on the menu, and you can click on "Move" or "Copy" and then select your target folder. SD-It's recommended to create a separate folder there, for example, Photo_Archive, so as not to mix files.
The process of copying large amounts of data (e.g. 10 GB or more) can take time. Do not fold the conductor or lock the screen so that the system does not stop the background process. Once the transfer is complete, be sure to check if the files are opening from a new location, and only then delete the originals from internal memory.
| Parameter | Internal memory. | SD-card (Class 10) | SD-map (UHS-I) |
|---|---|---|---|
| Reading speed | High (up to 500 MB/s) | Medium (up to 90 MB/s) | High (up to 100+MB/s) |
| Recording speed | Very high. | Low/Mediocre | Tall. |
| Reliability | Tall. | Medium | Tall. |
| Risk of loss | Low. | High (physical wear and tear) | Medium. |
Why are some photos not copied?
Automation through Files and Cloud Services
For those who prefer to minimize manual intervention, there are automation scenarios. The Files app built in (not to be confused with Explorer, it is a more advanced manager from Xiaomi) allows you to create sorting rules. However, a more reliable way is to use third-party utilities such as Tasker or FolderSync, available on Google Play.
These apps can track the appearance of new files in the folder DCIM/Camera and move them instantly to SD-Set up a scenario like this takes time, but the result is worth it: your phone will always have free space. In sync settings, specify the condition "Only through Wi-Fi" so that mobile traffic is not wasted.
Also worth considering is the use of cloud storage with the function “Free space” services like Google Photos or Yandex.Disk can store originals in the cloud, and only leave thumbnails on the device, which does not transfer the photo to the memory card physically, but effectively solves the problem of space shortage.
⚠️ Note: When using third-party applications for automation, give them the necessary permissions to access files.+ The program will not be able to move data.
💡
Use memory cards labeled A1 or A2. These application speed classes allow faster downloading of thumbnails in the gallery, making viewing photos from the card as smooth as from internal memory.
Solution: Reading errors and hidden files
Often, users are faced with a situation where the card is inserted, but the phone does not see it or writes an error. First of all, check the contacts of the card and the tray. Oxidation or dust can disrupt the contact. Wipe the contacts with a soft dry cloth and paste the card until the characteristic click.
If the problem is a software glitch, try rebooting the device. Network resets rarely help, but this is a last resort. Also check the file system format: Xiaomi works best with FAT32 for cards up to 32 GB and exFAT for larger cards. NTFS format may not be supported without third-party software.
Another common problem is that hidden.thumbnails folders appear on a memory card that can take up gigabytes of space, which is the gallery sketch cache, and you can clean them through storage settings or with specialized cleaners, but they will be recreated when you view the photo.
Optimization of the gallery with an external drive
After moving a large amount of data, the gallery may start to work slower, because the system needs to index new files, and give the phone time (usually 15-30 minutes in the background) to complete the media scanner process.
To speed up the work, you can turn off the display of video in the gallery if they are stored on a slow map. In the settings of the Xiaomi gallery there are display filters, it is also recommended to defragment regularly (although this happens automatically in Android), or just periodically check the map for errors through the computer.
Using a memory card extends the life of the smartphone’s internal flash memory, which has a limited life of overwriting cycles. By moving heavy media files outward, you reduce the wear and tear of the main drive, which has a positive effect on the overall speed of the MIUI interface.
💡
Regular backup of data from SD-PC cards are the only guarantee of the safety of your photos, as external drives are less reliable than the internal memory of the phone.
