Owners of Xiaomi Redmi 8 smartphone often face a lack of free space in internal storage, especially if high-resolution video is actively being shot or a lot of media from instant messengers is downloaded. Transferring photos to an external drive is the most effective way to free up precious gigabytes without removing important images and losing the quality of media files. Modern versions of the MIUI shell provide built-in tools for managing files, which makes the process of migrating data simple and accessible even for inexperienced users.
In this article, we will discuss in detail the algorithm of actions that will help you safely move the archives of images to the microSD card. You will learn about the nuances of the Android file system, the features of formatting drives and how to automate the process of shooting directly to an external medium. Proper storage will not only speed up the operation of the operating system, but also prevent critical failures when installing updates or new applications.
Before you start manipulating files, you need to make sure that the memory card is healthy and correctly installed in the device. The speed of writing and reading data depends on the class of the drive used, so it is recommended to use UHS-I or higher cards for comfortable work with heavy photos. Ignoring technical requirements can lead to errors when saving files or damage to an existing archive.
⚠️ Before starting a large-scale data transfer, be sure to back up important photos on a cloud service or computer, as interrupting the recording process can lead to partial loss of information.
Preparation of memory card and smartphone for work
The first step in the memory optimization process is to physically install the microSD card into the corresponding device slot. In the Redmi 8 model, the SIM card tray is combined, so it is important to correctly position the drive according to the circuit applied on the removable tray so as not to damage the contacts. Once the smartphone is turned on, the system automatically recognizes the new media and can suggest formatting it for use as internal or portable storage.
The choice of formatting type is key to the future use of the drive. If you plan to use the card only on this phone and store applications on it, you can choose the “Internal Storage” mode, but for simple transfer of the photo, you should leave the “Portable Storage” mode, which will ensure that the file is compatible with other devices, such as computers, tablets or cameras, without the need for re-formatting.
File system plays an important role in stability. For cards up to 32 GB, FAT32 is the standard, whereas larger drives are usually formatted in exFAT. The MIUI-based Android operating system will choose the optimal format, but if you format a card through a computer, make sure that you choose a compatible file system, otherwise the phone may not see the media.
☑️ Pre-transfer check
It is also worth noting that the speed of the interface can temporarily decrease immediately after installing a new map, while the system indexes the contents. This process is background and does not require user intervention, but in the first minutes it is better to refrain from active actions with files.
Use of a standard conductor for transfer
The most reliable and controlled way to move images is to use the regular Explorer app, which is preinstalled on all Xiaomi smartphones, which allows you to visually track the movement process, select specific folders and avoid duplicate files. To start work, you need to launch the application and go to the section responsible for the internal storage of the device.
In the Android directory structure, photos taken on camera are saved by default to the DCIM/Camera folder, and images from messengers are often in Pictures or Android/media folders. Once you select the desired files or entire directories, you click on the “Move” button in the bottom menu and select the action “Move” or “Copy”; the difference between these commands is significant: copy creates a duplicate by taking up additional space, and moving physically changes the path to the file.
After selecting the action, the system will prompt you to specify the target directory. You need to go to the root of the memory card, which is usually displayed as /storage/sdcard1 Or it's called a brand of storage device, and it's called a folder, Photo_Archive, It can help to keep order and quickly find the right pictures in the future. The process of transferring a large number of files can take several minutes, during which it is not recommended to close the Explorer application.
| Action. | Impact on memory | Risk of data loss | Speed of implementation |
|---|---|---|---|
| Copying | Takes up a seat in two places | Low (original remains) | Tall. |
| Relocation | Frees up internal memory | Medium (when power fails) | Depends on the volume. |
| Removal | Deletes the file irrevocably | Tall (no backup) | Instantly. |
| Compression to archive | Save space, but requires unpacking | Low. | Low (spending CPU resources) |
It is important to understand that when moving system thumbnails (thumbnails), the gallery may temporarily not display a photo until it reconfigures the cache, which is normal behavior of the system that corrects itself after restarting the device or reopening the gallery. Using standard tools minimizes the risk of software conflicts that can occur when using third-party software.
Configure automatic saving to SD-map
To avoid the need for regular manual photo transfer, you can set the smartphone camera to automatically save pictures immediately to the external drive. This feature is built into Xiaomi’s standard Camera app and activated via the settings menu available via a three-bar or gear button. SD-map transfers the main data stream directly to the external storage.
However, it is worth considering that not all third-party applications support this feature or work correctly with external storage. For example, social networks or document scanners may still save files to internal memory, ignoring system settings, in which case you will need to manually change the way you save in the settings of each particular application or use third-party programs for the camera.
The speed of writing to a memory card can become a bottleneck when shooting high-resolution video or taking serial photos. If you notice delays between frames or interruption of recording video, this may indicate a slow speed of the memory card class, in which case it is recommended to reduce the recording quality or replace the drive with a faster version marked with a Class 10 or U3.
Why the camera sometimes ignores the camera SD-map?
⚠️ Attention: When actively using a memory card for recording photos and videos, the resource of its cells is consumed faster than with normal storage of archives, so regularly check the state of the drive with special utilities.
Work with Gallery and Cloud Services
The MIUI Gallery app can recognize files on an external drive and display them in a shared list, but sometimes you need to manually scan media files. If you don't display photos after transferring them, you can use Hide Albums and then turn them back on, which will force the system to update the media database, which is especially true after large data transfers.
Using cloud services like Google Photos or Mi Cloud can be a great alternative to physical media, but requires a stable Internet connection. Synchronization settings allow you to automatically upload originals to the cloud and free up space on the device with a single button. However, for Redmi 8 users with limited traffic or no Wi-Fi, local storage is preferable. SD-map.
It is important to remember the folder structure when synchronizing: if you move a photo to the root of the map or to a non-standard folder, artificial intelligence algorithms can less recognize objects and faces in pictures. For better work of smart albums, it is recommended to save the folder structure proposed by the system, or use standard DCIM directories even on an external medium.
💡
Use the “Clear Memory” feature in Google Photos only after you make sure that the photos are fully uploaded to the cloud and have a tick icon, otherwise you risk losing the originals.
Some users prefer to hide albums from the memory card from prying eyes, using the function of hiding albums in the gallery settings.This does not protect files with a password, but removes them from the overall stream of the tape, making viewing more convenient. For real protection of confidential data, it is better to use the built-in functionality of the “Hidden Album” with protection. PIN-fingerprint.
Solving errors when transferring files
One of the most common problems is the message “File is corrupted” or the system’s refusal to copy data. Often this is due to the NTFS file system, which Android cannot read without special drivers or root rights. If your card is formatted on a Windows computer without selecting FAT32/exFAT, the phone can see it, but can’t write data to it or read certain types of files.
Users may also face restrictions on access rights, especially on newer versions of Android, where tightened security prevents applications from accessing certain parts of external memory, in which case, when trying to move, the system can request permission to access files, which must be confirmed by clicking the “Allow” button in the system dialog.
If the transfer process is stuck at a certain percentage, it may indicate broken sectors on the memory card or physical malfunction of contacts. Remove the card, wipe the contacts with a wipe or soft cloth and paste back. If the error is repeated on different files, it may be that the drive has exhausted its life and needs to be replaced.
adb shell pm grant com.android.documentsui android.permission.WRITE_EXTERNAL_STORAGEIn rare cases, resetting the configurations of the conductor applications through the Apps menu in the phone settings helps. Cleaning the cache and data of the Explorer or Files application itself can eliminate software glitches that prevent the correct operation of the file system.
💡
Most portability errors are due to the file system format of the memory card or insufficient access rights of the conductor application.
Optimization and maintenance of memory card
To maintain high speed external drive recommended periodically defragmentation, although modern file systems exFAT less prone to fragmentation. on Android, this can be done through special applications from the Play Market, which analyze the state of the drive and optimize the location of files. Regular maintenance prolongs the life of the card and prevents the occurrence of read errors.
It is important to properly remove the memory card before physical deletion to avoid damaging the file table. In modern versions of MIUI, simply go to the storage settings and press the "Extract" button, after which the system will report a safe extraction. Ignoring this step can lead to the fact that the next installation of the phone will require formatting the card, which means complete loss of data.
Regularly check the card for errors using built-in diagnostics or connecting it to a computer. File system error check and correction can restore access to damaged sectors and save important photos. Preventive inspection every few months will help avoid unpleasant surprises at the most inopportune time.
