Xiaomi smartphone owners often face a lack of free space in the memory of the device, especially if you actively use the camera and shoot video in high resolution. Transferring accumulated photos and videos to a microSD card is the most effective solution to free up precious gigabytes of internal memory without losing important data. Modern models such as the Redmi Note or the flagship Xiaomi Mi often do not support memory expansion, but if your device is equipped with a card slot, it is a sin not to take advantage of this opportunity.
The file transfer procedure may seem complicated at first glance, but standard MIUI or HyperOS shell tools allow you to perform this operation in just a few touches. It is important to understand that the correct distribution of data not only frees up space, but can also have a positive effect on the speed of the system, since internal memory is often overloaded with the cache of applications. In this guide, we will discuss all the nuances of working with external drives on Xiaomi devices.
Before you start taking action, you need to make sure your memory card is properly and correctly defined by the system. If you just bought a new drive, the phone will suggest formatting it, and this is a must for stable operation. Ignoring formatting or using a card with a file system that is incompatible with Android will lead to read errors. Let's look at how to prepare the device for external storage.
Preparation of memory card and setting up in MIUI
The first step after you physically put a card into a SIM card tray is to program it. A MIUI-based Android system usually detects the new media itself and puts the notification down the curtain. If you miss the notification, you have to manually go to the storage settings to initiate the preparation process. Without this step, writing files to an external medium will not be possible.
To get started, open the Settings menu and find the About Phone section or immediately go to Advanced Settings, where memory management is often located. In newer versions of the firmware, the path may look like Settings → Memory. Here you will see information about the internal memory occupation and the status of the SD card. If the system offers to choose a mode of use, choose the option for storing files (photo, video, music) rather than expanding internal memory, since the second option works unstable on many models.
The formatting process will completely remove all data from the card, so if it already has files, be sure to copy them to the computer in advance. Once the operation is confirmed, the system will format the drive to the exFAT or FAT32 file system, which is optimal for working with multimedia.
⚠️ Warning: Do not remove the memory card or restart the smartphone during formatting. Interrupting the system file writing process can damage the file table and cause the storage device to fail.
Once the formatting is successfully completed, the status bar will have a memory card icon, and you can now move directly to data transfer, and you should immediately set the camera to save new images to an external medium by default, eliminating the need for constant manual sorting in the future.
💡
Use UHS-I or higher speed memory cards to record 4K video, otherwise frame skips may occur when shooting.
Use of a standard conductor for transfer
The easiest and most reliable way to move photos is to use the File Manager app, which is pre-installed on all Xiaomi smartphones and has enough functionality for batch processing of files. You do not need to download third-party applications, which reduces the risk of accidental deletion of system data.
Open Explorer and go to Internal Memory. You need to find the DCIM folder, which is the default folder for the Camera with all your snapshots. Select the photos you want or entire folders with a long press, and then select Copy or Move from the bottom menu, and the difference between those features is critical: copying will leave the originals in place, and moving will remove them from internal memory after the process is complete.
After selecting the action, go back to the Explorer root and select SD-Create a new folder, like this, Photos_Archive, So you don't mix files with the system directories, and open it. Press the Insert button at the bottom of the screen. The speed of copying will depend on the class of your memory card and the number of files.
☑️ Pre-transfer check
If you are carrying a very large amount of data (for example, 50-100 GB, the process can take a considerable time, in which case it is better to connect the phone to the charger to avoid battery drain at the most inopportune time, and it is not recommended to use the phone for games or heavy tasks while actively recording on the device. SD-map.
Set up the camera to shoot immediately on SD-map
To avoid manual photo transfers in the future, it is much more convenient to set up automatic snapshot saving directly to an external drive, which is built into the standard Camera app on Xiaomi and activated in a couple of taps, especially for users who take a lot of photos and do not want to constantly monitor the filling of internal memory.
Launch the Camera app and click on the three horizontal bars in the upper right corner to open the settings menu. In the settings list, find an item that may be called Save on the Settings menu. SD-You can activate the switch in front of this point, and from now on, all new photos and videos will automatically be recorded to the external drive.
It is worth noting that some shooting modes, such as Portrait with complex blur effects or shooting in high-resolution HDR format, can still store data in internal memory to ensure processing speed.
| Parameter | Internal memory. | SD-map | Recommendation |
|---|---|---|---|
| Recording speed | High (UFS 2.1/3.1) | Medium (depending on class) | 4K video is better than internal video |
| Volume | Limited by the model | Up to 1 TB (usually) | SD for photo archive |
| Reliability | Tall. | Average (loss risk) | Make backups. |
| Access to applications | Complete. | Requires permits | Check access. |
If you switched save to a map and new images still appear in the internal memory gallery, try restarting the device. Sometimes the system requires restarting image processing services to apply new storage settings.
Working with the Gallery application and cloud services
The standard Xiaomi Gallery can not only display photos, but also manage their location, although the portability functionality there is less obvious than in Explorer. Opening the album, you can select several photos, click the More button (three dots) and select the option to move if the system allows you to do this in your version of MIUI. However, most often the Gallery is used for viewing, and file management is better delegated to the Explorer.
Special attention should be paid to synchronization with the cloud Xiaomi Cloud or Google Photos. If you have synchronization enabled, then when transferring a photo to a memory card, the cloud service may perceive this as deleting the originals and clearing the cloud copy. To avoid data loss in the cloud, it is better to temporarily disable synchronization before transferring files or make sure that copies are already uploaded to the server.
Using cloud storage in conjunction with SD-And the card creates a great backup system, so you can store the actual images on the map for quick access, and the most important frames are duplicated in the cloud, and this provides dual protection against data loss in the event of a smartphone breakage or memory card damage.
⚠️ Note: When removing photos from internal memory after transfer, make sure they are opened correctly from a new one. SD-Do not clean the original folder until you have checked the integrity of the files.
Transfer of data via computer (PC)
If wireless methods seem inconvenient or you need to transfer terabytes of archival data, using a computer will be the fastest solution. USB-cable and select the menu on the phone screen file transfer mode (MTP). This will allow the computer to see the internal memory and map. SD disc-like.
On your computer, open up your phone's internal memory, find the DCIM folder, and copy the contents of the Camera folder to your PC's hard drive. Then go to the memory card section (it will be displayed as a separate removable drive) and paste the copied files into the corresponding folder. The good thing about this is that you create an intermediate copy on your computer that serves as an additional backup.
When working through a computer, it is also convenient to audit files: remove blurred images, duplicates and screenshots, which often take up a lot of space. Use sorting by date or size to quickly find the "heavy" video files that most load the memory of the smartphone.
Why can't the computer see the memory card?
Once you have finished copying, make sure to safely extract the device from Windows before you turn off the cable.Abruptly shutting down the card file system can damage the file system and the phone will stop seeing it until the next formatting.
Typical problems and ways to solve them
Even if you follow all the instructions, users can encounter errors. One of the most common problems is the message "SD-The card is corrupted" or "Can't read the card. "This is often solved by re-formatting directly on the phone. If the error is repeated, try checking the card for errors through the computer by running a disk check in the properties of the drive.
Another common situation is that photos are moved but not displayed in the Gallery, which means that the Android media scanner hasn't updated the database, so to fix this, you can restart the phone or use the file hiding app to re-scan folders, and also check if the photo folder on the memory card has a.nomedia file that prevents the system from displaying media from this directory.
If the memory card is detected but the files are not written to it (the “No Access” or “Write Protected” error), check the physical switch on the card adapter (if you use an adapter) or access rights in application settings. Sometimes antivirus or MIUI system restrictions block the entry to certain system folders on an external medium.
💡
If the phone stopped seeing the card after transferring the data, first remove and paste it again, and then check the formatting.
In rare cases, the problem lies in the phone slot itself or contacts. Gently wipe the memory card contacts with a soft eraser or dry cloth. Contact oxidation is a common cause of unstable operation, especially if the phone was operated in wet conditions.
