Owners of the Xiaomi Redmi 7 smartphone often face a situation where the built-in storage capacity of 32 or 64 GB is no longer enough for storage of multimedia. The camera of this device shoots in high resolution, and modern applications take up more space, which leads to constant notifications about the lack of space. The solution lies in the competent use of the microSD card slot, which allows you to significantly expand the available volume.
Transferring existing images and videos to an external medium is the first step to optimizing the device, a procedure that not only frees up space for installing new programs, but also increases the overall response rate of the system, as a crowded system partition often causes interface brakes. In this article, we will discuss in detail all the ways to move files and configure storage.
Before you start manipulating the file system, it’s important to make sure your memory card is working properly and installed correctly in the slot.The Xiaomi Redmi 7 supports cards up to 256GB, allowing you to create a vast media library right in your pocket.We’ll look at both standard methods through the file manager and more advanced ways to integrate the drive into the system.
Preparation of memory card and smartphone for work
The first step should always be to physically install the media and check it basic: insert the MicroSD card into the SIM card tray, observing the orientation of the contacts, and wait for the notification of the connection of the new device. If the system suggests formatting the drive, agree, but pre-copy important data to the computer, if it already has.
After the physical installation, you need to check the status of the card in the settings. Go to the Settings menu → The phone. → The storage room, to see the total volume and the distribution of the space, you'll see two sections here: internal memory and external memory. SD-Make sure the system correctly recognizes the amount of your storage.
💡
Use UHS-I or higher speed memory cards to record high-resolution video to avoid delays when saving frames.
It is important to understand the difference between drive modes. By default, the card works as a portable storage, but to fully transfer application data and system files, it may require formatting as an internal storage. Formatting will completely clear the card, so make sure you have a backup of important documents.
- 📱 Make sure the smartphone is turned off or unlocked before removing the tray.
- 💾 Check the card for errors with your computer before installing it on your phone.
- 🔒 Lock the SIM card tray before clicking to avoid getting dust inside the case.
Use of a standard conductor for transfer
The easiest and safest way to move photos is to use the built-in Explorer app. Find an icon on your desktop with a folder image or search the system by typing the name Explorer or File Manager, which is pre-installed on all devices with a MIUI shell and does not require add-ons.
Inside the app, go to the Images or Internal sectionshared_storage», file-store DCIM/Camera. Select the photos you want with a long press, then select the "Move" or "Copy" button in the bottom menu. The system will suggest selecting the destination where you want to specify your destination. SD-map and create or select a target folder.
☑️ Pre-transfer check
The process of moving a large number of files can take time, depending on the speed of writing the card and the amount of data. During the operation, it is not recommended to run heavy applications or games, so as not to put extra strain on the processor and memory controller.
⚠️ Note: When using the Cut (Move) function, the original files are deleted only after successfully writing to a new medium.
Set up the camera to shoot directly on the SD card
To avoid manually transferring images in the future, it is advisable to set up the camera app to automatically save media files immediately to the external drive. Open the Camera app, click on the three bars in the upper right corner to log in to the menu and select Settings.
In the list of parameters, find the item "Save to SD-Activate this switch. From now on, all new photos and videos will be recorded directly into the memory of the card, bypassing the internal storage of the Redmi 7 smartphone.
What to do if the switch is inactive?
It’s worth noting that some system features, such as slow motion or panoramas, can still use internal memory to buffer data before the final recording, and when shooting in RAW or 4K (if supported by modification), the speed requirements of the card increase many times over.
- 📸 Automatic storage frees up to 40% of internal memory when using the camera.
- 🎥 High-resolution video requires cards with a recording speed of at least 30 Mb/s.
- 🔄 When resetting the camera settings, the save parameter SD It may be reset, check it after updates.
Formatting the map as an internal storage
For users who want to integrate the memory card as much as possible, Adoptable Storage is available, which allows you to format an external card so that the system considers it part of the internal drive. SD-not only photos, but also heavy applications and their data.
To activate this function, go to Settings → The phone. → The vault, choose yours. SD-A map from the list and click on the menu button (three dots or gears). Select "Format as internal storage." The system will warn that all data will be destroyed, and the card will be encrypted and tied to that particular device.
Once the process is complete, the system may suggest moving the already installed applications and media files to a new space. Accept the transfer to make room instantly. Now your memory card will become an integral part of the system, and it will be impossible to remove it without losing data and resetting the settings.
| Parameter | Portable storage | Internal storage |
|---|---|---|
| Use of the | Photos, videos, documents | Applications, games, data |
| Portability | You can move it to another phone. | It's tied to one device. |
| Security | Data available on PC | Data encrypted |
| Speed of operation | Depends on the card. | It requires high speed. |
⚠️ Warning: Once formatted as an internal storage, the card is encrypted, and when you try to insert it into another smartphone or connect it to a computer, the data will not be read without formatting.
Working with cloud services and synchronization
An alternative to physical file porting is using cloud storage, such as Google Photos or MI Cloud, which allows you to automatically upload photos to the Internet, freeing up space on your device. In the Google Photos settings, enable the “Free Space” feature, which will delete local copies of already uploaded images.
Using the cloud is especially important if you change devices frequently or fear physical memory card damage. However, this method requires a stable Internet connection and free space in a cloud account. For Xiaomi Redmi 7, a standard Google account size (15 GB) may not be enough for a full backup.
💡
Combination SD-Maps and cloud storage provide dual data protection: a physical copy on the map and a remote backup in the cloud.
Configure sync only over Wi-Fi so that you don't waste mobile traffic. In your network settings, specify a limit on downloading large files only when you connect to a wireless network, which allows the fonuvo to upload photos at night or when you are in the office without affecting the Internet speed during the day.
Possible problems and ways to solve them
During operation, users may experience card reading error or slow system operation. Often the cause is the FAT32 file system, which has a limit on the size of one file to 4 GB. If you shoot long videos, the system may not save the file or interrupt the recording.
The solution is to format the map into an exFAT file system that is free of this limitation and works better with large amounts of data. However, standard Android tools may not be available for exFAT formatting and require the use of a PC with programs like SD Formatter.
Also (a common problem) is the “merge” of the path to files after updating the firmware. Gallery can stop seeing photos if the folder structure changes, in which case scanning media files through special applications-scanners or simply restarting the device, which causes the system to re-index the contents of the drives.
- 🐌 Slow operation of the interface when opening a photo indicates a low speed of reading the map (class below 10).
- ❌ The “File is corrupted” error often occurs when you remove a card without first unmounting.
- 🔍 If the photos are missing, check the hidden folder.trash or the basket in the gallery where the deleted files fall.
⚠️ Warning: Never remove a memory card during the process of recording a photo or video, guaranteed to damage the file table and lose the last material taken.
