Owners of budget smartphones like the Redmi 9A often face a shortage of built-in storage. The standard 32 or 64 gigabytes are quickly filled with instant messengers, photos and system files. The device's built-in memory is not rubbery, and the system begins to demand space, and the only effective solution in this situation is to use an external drive.
Modern mobile OSes allow you to manage storage flexibly, transferring data arrays to more capacious media. In this article, we will discuss how to transfer data correctly to the Xiaomi Redmi 9A memory card to free precious megabytes. You will learn to move photos, video files and even some applications using the standard system tools.
The expansion procedure does not require root rights or complex software, and all the necessary tools are already built into the MIUI shell, the main thing is to follow the sequence of actions and understand which types of files can be moved and which are better left on the system disk.
Preparation of memory card and installation in Redmi 9A
The first step is to physically install the media, and make sure you get a quality MicroSD card, preferably a Class 10 or a speed class. UHS-I. Slow cards can cause the interface to hang when reading data. Turn off your smartphone or use the hot replacement feature if supported by your firmware version, and paste the card into the appropriate tray slot SIM-map.
Once the device is turned on, the system will automatically detect a new drive. The card file system must be compatible with Android, usually exFAT or FAT32. If the card is new, the system will suggest formatting it. Formatting will completely remove all existing data from the card, so back up important files on your computer in advance.
⚠️ Warning: If you're using a map that already had data on it, be sure to copy it to your computer before formatting.The process of preparing the drive for Android will destroy all current folder structure.
In some cases, the system may suggest using the card as internal memory. For the Xiaomi Redmi 9A with its modest processor characteristics, this mode may be redundant. It is better to leave the card as a portable storage, which will allow you to easily transfer it to other devices without losing access to files.
💡
Use memory cards up to 256 GB for maximum compatibility. More capacious models (512 GB and above) may run unstable or require additional formatting on a PC.
Configuring storage in the MIUI system
Once you install the media, you need to make sure that the system sees it correctly. Go to the settings menu and find the partition responsible for memory. The path may vary slightly depending on the version of MIUI, but the logic remains the same. You need to open Settings → About Phone → Storage.
Here you'll see general information about the occupation of the space, and you'll see two sections: Internal storage and SD-If the card is displayed as Portable Storage, it is ready to work in standard mode, in this mode you can store any media files and documents.
It is important to check the status of the read/write error. If the system says that the card is damaged, try to remove and paste it again. Sometimes the contact in the slot may not be perfect. It is also worth checking the card on the computer with utilities like H2testw to prevent buying a fake.
| Type of data | Recommended seat | Impact on speed |
|---|---|---|
| Photos and videos | SD-map | Minimum |
| System applications | Internal memory. | Critical. |
| Cash messengers | SD-map (when set up) | Average. |
| Games | Internal memory. | High. |
Transfer of photos and videos through the Gallery
The easiest way to free up space is to move media content. The standard MIUI Gallery app has built-in functionality to move around. Open the app and select an album, like "Camera" or "WhatsApp Images."
Select the files you need by holding your finger on one of them, and then mark the others. Press the "More" button (three dots) and select "Move to the album." The system will suggest you select the target folder. SD-If you don't, you can create a new folder directly on the external media.
⚠️ Note: When moving a large number of files (more than 500 pieces), the process can take a long time.Do not turn off the smartphone screen and do not close the Gallery app until the operation is completed to avoid corruption of files.
The alternative is to use the built-in Explorer. DCIM You can select the contents of the storage, and you can select copy or cut. SD-You can use the Cut feature faster, because you don't need a double write operation, but you're more risky if you're powered out.
☑️ Transfer of media files
Moving applications to an external drive
The issue of installing applications SD-The map in modern versions of Android is partially solved. Since Android 6.0, Google has limited the full portability of software for security and stability. MIUI There are opportunities to move some of the data.
Go to Settings. → Annexes → All applications. Select the program you want, like a heavy game or a social network. If the app developer has allowed the transfer, move to the button. SD-If the button is grey or missing, the application must remain on the system disk.
Why can't we move all the apps?
There's a caveat with the cache. Even if the app itself is left inside, some of its heavy resources can be moved, so in the app menu, select Memory and click Change if available, and this will allow you to upload graphics and additional data packets to an external medium.
It is not recommended to transfer messengers like Telegram or WhatsApp to the map if the card has a low write speed, this will lead to slow downloading of correspondence history and lags when sending media, it is optimal to keep active applications on internal flash memory.
Using a Explorer to Manage Files
To fine-tune it, use the standard file manager, which lets you see hidden folders and system directories, open the Explorer app and switch to category or folder browsing mode.
Often users forget about the Download folder. Browsers and instant messengers save all downloaded documents there. Find this folder in the internal storage, select files and move them to a similar directory on the Internet. SD-This often frees up a few gigabytes of space.
It's also worth checking your social media folders. Viber and WhatsApp create separate directories for media. The path usually looks like Android/media/com.whatsapp or WhatsApp/Media. By moving the contents of your Images and Video folders to an external medium, you free up space, and the apps will continue to work correctly, counting the paths to new files.
💡
Regular cleaning of the Downloads folder and transferring old documents to SD-The most effective way to maintain order without losing important data.
Setup of the camera for shooting SD-map
To avoid manually transferring files in the future, set the camera to save photos and videos immediately to an external medium. Open the Camera app and click on the menu icon (three bars or gear) in the corner of the screen.
In the settings menu, find the item "Save to" SD-"Map" or "Storage." Activate the switch. From now on, all new images and videos will be recorded directly to the memory card. This is especially true for recording high-resolution video that takes up a lot of space.
⚠️ Note: When recording video on the SD-Make sure the card has a high write speed (minimum 30MB/s).If the card speed is low, the video recording may be interrupted and the file will be damaged.
Note that Panorama mode or RAW shooting may require a high buffering speed available only in internal memory, in which case the camera can automatically ignore the setting and save the file inside the smartphone.
