Owners of the popular budget smartphone Xiaomi Redmi 8 often face a lack of built-in storage, especially if the device has a version with 32 GB of memory. The camera of this device is able to take high-quality pictures that quickly fill the available space, causing slowdown of the system and the inability to install new applications. The solution lies in the competent use of an external microSD storage format, which allows you to expand the capabilities of the gadget without losing important data.
The process of moving media files does not require root rights or complex software, since the MIUI shell provides built-in tools for managing files. However, there are nuances related to Android access rights and the features of the memory card as an internal or external drive, understanding these mechanisms will help avoid data loss and ensure stable operation of the device in the long run.
In this guide, we will go through all the steps from map preparation to automatically configuring the camera to save the images immediately to the external media, you will learn how to format the drive correctly so that the system can see it, and what actions to take if standard transfer methods do not work, which will allow you to free up precious gigabytes of internal memory for system needs.
Preparation of memory card and smartphone for work
Before you start transferring files, you need to make sure that your memory card is technically sound and compatible with the device. Xiaomi Redmi 8 supports drives up to 256 GB, however, for stable operation, it is recommended to use cards of class speed 10 or higher, such as SanDisk Ultra or Samsung EVO. Using slow cards can lead to delays when shooting videos or a long gallery opening.
Insert the card in the corresponding slot, which in this model is combined with a tray for the second SIM-To extract the tray, use a special paper clip included in the kit or a thin needle, gently pressing the hole next to the tray on the lower end of the case. It is important to insert the card on the correct side, focusing on the golden contacts, so as not to damage the pins of the reader.
After the physical installation, the system must automatically identify a new medium if a detection notification appears on the screen. SD-In some cases, if the card has been previously used on another device, Android may require formatting it, as the file system may be incompatible or contain errors.
- 📱 Make sure your smartphone is turned off or unlocked before installing the card.
- 💾 Check the card for physical contact damage.
- ⚙️ Use only the original tray for the SIM and SD map.
- 🔍 Make sure the card is not protected from writing (lock switch on the adapter).
⚠️ Note: Formatting a memory card completely removes all data from it. If there are important files on the drive, pre-copy them to your computer or cloud storage.
The MIUI formatting process is fast enough to optimize the file system for the mobile device, and once it's done, the map is available for write and read, and you can move on to setting up the save paths.
💡
Use memory cards only from trusted manufacturers. Cheap analogues from marketplaces often have real capacity at times less than claimed, which will lead to loss of photos after a few months of use.
Configure the save path in the Camera app
The most effective way to free up space is to set up automatic saving of new images directly to the external drive. To do this, open the standard Camera application and go to the settings menu by clicking on the three horizontal bars in the upper right corner of the screen. In the list of parameters that opens, you need to find the item responsible for priority storage.
In the settings menu, find the Additional settings section or immediately see the option Save to SD-Activate this switch. From now on, all new photos and videos will be recorded by default to external memory, bypassing internal storage. This is especially useful when shooting high-resolution video that takes up a lot of space.
It’s worth noting that some shooting modes, such as Portrait or HDR shooting, can still save copies or processed versions in internal memory to speed up the processor’s work, and if you take screenshots of the screen, they are saved by default to the system folder, unless you use special apps to manage screenshots.
If new photos continue to appear in internal memory after this option is enabled, try restarting the device. Sometimes the system requires restarting the media scanner services to correctly apply the new save path settings.
- 📷 Open the Camera app and click on the menu (three bars).
- 📂 Select the item "Save to" SD-map and activate it.
- 🔄 Take a test shot and check its location in the Gallery.
- ⚡ Restart your phone if the settings do not apply immediately.
💡
Automatic camera setup saves time and nerves as you no longer have to manually move files after each photo shoot.
Using a standard Explorer to transfer files
To move existing photos that were taken before the map was set up, you will need to use a built-in file manager. In Xiaomi smartphones, this application is called Explorer and has a characteristic yellow icon with a folder. It provides full access to the file system of the device.
Run Explorer and at the top of the screen select the tab that displays the device's internal memory (usually signed as Internal Storage or Internal Storage). Find the DCIM folder that stores the Camera folder with all your snapshots by default. Highlight the desired photos with a long press or select all files through the menu.
After allocating files, click the More (three dots) button at the bottom of the screen and select Move or Copy action, preferably as it frees up space immediately, but copying is safer if you fear losing data in the process. Then go back to the main Explorer menu and select yours. SD-map.
The path to photo: internal drive → DCIM → Camera
Destination path: SD- → DCIM → Camera (or folder you created)In the external memory window that opens, go to the DCIM folder and create a new folder or select an existing Camera. Press the Insert button at the bottom of the screen. The system will begin the transfer process, the progress of which will be displayed as a percentage.

Comparison of copying and moving methods
When working with files, users often get confused in terms, not understanding the difference between copying and moving. This is a critical point when managing smartphone memory, since the choice of action depends on the final result and the amount of free space. Below is a table to help you choose the right method for your situation.
| Parameter | Copy | Move it | Send (Bluetooth/Wi-Fi) |
|---|---|---|---|
| Original | Stays in place. | Removed from the starting position | Stays in place. |
| Occupied seat | Increased (files duplicated) | Not changing (files change address) | It doesn't change. |
| Speed. | High (within one device) | Tall. | Low (depending on protocol) |
| Risk of loss | Minimum | Medium (when power fails) | High (joint break) |
Use Copy if you want to back up important photos on a memory card, but leave the originals in internal memory for quick access. This is useful before you run a risky operation with the system or firmware.
The Move function is the primary function for cleaning up internal memory, physically changing the file storage address in the file system, freeing up space in the original partition, and it's the most logical choice for archiving old photos and videos.
⚠️ Warning: Do not interrupt the process of moving large video files. If the battery runs out or you close Explorer during operation, the file may become corrupted and unreadable.
What do I do if the process is stalled?
Storage settings for other applications (WhatsApp, Telegram)
Many users don't realize that not only are the camera photos the most important memory load, but also the media files from messengers, apps like WhatsApp and Telegram, by default, store the images and videos they receive into internal memory, and fortunately, some of them can change the way they save.
WhatsApp needs to go to Settings → Chats. There's Media Visibility and Storage Settings, but direct change. SD-cards in newer versions of Android are often blocked by security, in which case, it is recommended to use the function of cleaning the storage inside the application itself, removing old files.
In Telegram, the situation is similar: go to Settings → Data and memory → The path to files. If your version of the app and Android allow, you can choose to go to the top of the list. SD-If you don't have that option, the files will be stored in the internal memory and will have to be cleaned periodically through cache.
- 📱 Open the settings of a specific messenger.
- 💾 Find the "Data and Memory" or "Storage" section".
- 🗑️ Set up auto-remove media or change the save path.
- 🔄 Regularly clean the app cache through your phone settings.
To fully automate the process, you can use third-party file managers such as Total Commander or FX File Explorer, which have automatic file transfer functionality on a schedule. This requires more deep customization, but eliminates manual work.
💡
Set up Telegram to auto-delete media from the cloud in 3 days or a week, which will save not only space on the phone, but also traffic, as files will not be constantly uploaded to cache.
Solution: If the phone can't see the memory card
When Xiaomi Redmi 8 stops seeing the memory card or files from it, it is not common, but it can be caused by a software failure or damage to the file system. The first step should always be to restart the device. If this does not help, try to remove the card, wipe the contacts with soft cloth and insert it again before the characteristic click.
If the system issues a message about a card being damaged, it may be necessary to re-format. → The phone. → The vault, find yours. SD-You can select the Format option, and remember that this action will destroy all the data on the media.
Sometimes the problem is file system incompatibility: Computers use NTFS or exFAT, and Android prefers FAT32 or ext4. If the card was formatted on a PC in NTFS, the phone can see it, but has no rights to write. Formatting through the phone interface solves this problem by bringing the file system to the desired standard.
⚠️ Note: If the memory card is defined as "Empty" or "Not Supported" after formatting on the phone, it may have physically failed.
In rare cases, cleaning the cache of the Media Scanner system application helps. To do this, go to Settings → Apps → All applications, search the Media Scanner (or Media Storage) in the list and click Clear Data. After that, the phone will index all files again.
💡
Most memory card problems are solved by simply formatting the smartphone itself, not the computer.
