Transfer data to memory card in Xiaomi Redmi Note 7

Owners of the popular Xiaomi Redmi Note 7 model often face a lack of built-in storage, especially if the base version with 32 or 64 gigabytes is used. Modern applications take up more space, and high-resolution cameras allow you to create three-dimensional photos and videos that quickly fill the available space. The solution lies in the competent use of a microSD card slot, which allows you to significantly expand the capabilities of the device without buying a new smartphone.

The process of data transfer does not require deep technical knowledge, but the MIUI shell has its own nuances that must be considered for the correct operation of the system. Unlike pure Android, some paths to settings are changed here, and the functions of porting applications can be limited by the manufacturer for the sake of stability of work. Understanding these features will help to avoid errors and loss of important information when working with an external drive.

In this guide, we will take a look at all the memory optimization techniques available, from simple media movement to complex settings through an engineering menu. You will learn how to make a memory card the main place to save new files and what restrictions the operating system imposes on installing programs. Proper file management will prolong the life of your gadget and speed up its operation.

Preparation of a memory card and installation in a slot

The first step is to physically install the drive and set it up in the system. For the Redmi Note 7, it is recommended to use cards of class speeds at least Class 10 or UHS-I, as this will ensure comfortable speed of writing and reading data. Using too slow cards can lead to slowing down the interface when viewing the gallery or launching heavy files.

Insert the card into the combined tray, keeping the correct orientation of contacts, and wait for the notification of the system when you connect a new device. Usually, the smartphone suggests you immediately use the drive as internal memory or as portable storage. The choice of Portable storage is more flexible, because it allows you to easily retrieve the card and connect it to other devices without losing data.

💡

Use memory cards up to 256GB for maximum compatibility with the Redmi Note 7, although the device theoretically supports large volumes.

Once connected, you need to format the drive if it has been used in other techniques, which will create a new file system that is optimal for working with Android. Remember to pre-copy important files from the card to your computer, as formatting will completely clear its contents.

⚠️ Note: Do not remove the memory card while actively recording videos or installing applications, this may cause file system damage and data loss.

Transfer of photos and videos through the Explorer

The easiest and safest way to free up space is to move your photos and videos to an external medium, and to do so, a powerful file manager is built into the MIUI shell that allows you to manipulate files without third-party software. Open the Explorer app and go to the DCIM folder, where the camera snapshots are stored by default.

Select the necessary files or entire folders with a long press, then select the Move or Copy function in the bottom menu. SD-Create a new folder and create a new folder, for example, Photos_Backup, Once the process is complete, the originals in the internal memory will be deleted (if you choose to move), and the freed space will be available to the system.

A similar procedure can be done with the Download folder, which often downloads documents and installation files from the browser. Regular cleaning of this section helps maintain order and prevents the internal storage from being filled with garbage files. If you often shoot 4K videos, it makes sense to immediately set the camera to save to the way on the map.

Configure the saving of new files to SD-map

To avoid manually transferring files every time, you can change the default settings for most system applications. This is especially true for the camera: open the Camera app, click three bars in the corner to log in to the menu, and select Settings. Find the Save on switch. SD-card and activate it, now all new pictures will immediately get to the external drive.

For browsers and messengers, settings may vary. In Google Chrome, go to the settings and find the Download point where you can specify the save path. In popular messengers like Telegram or WhatsApp, the way you save media files can also be changed in the Data and Storage section, which automatically directs the stream of incoming images and videos to the memory card.

Some applications may ignore the system settings of the paths if they are hard-coded by the developer, in which case you only need to periodically check the internal memory and manually transfer the contents of the folders. Android/data or MIUI, However, for basic smartphone functions, changing the paths in the camera and browser decides 80% space-deficit.

Transfer and installation of applications to an external drive

The question of transferring installed applications to Xiaomi Redmi Note 7 It's one of the most challenging because of the company's policies, starting with the shell version. MIUI 10 and above, the standard function of transferring applications to SD-The card has been removed from the settings for most users, and this is done to ensure stability, as external cards are slower than internal memory. eMMC/UFS.

However, it is still worth checking for a hidden option. → Advanced settings → Memory. If you have Preferred Installation Site, select SD-And then when you install new applications, the system will ask you to choose a storage location, and if you don't have one, it's locked in your firmware version.

There is a method of activating the transfer via USB debugging mode and ADB commands, but it requires a connection to a computer and certain skills. Using the adb shell pm set-install-location 2 command can force this feature to turn on, but does not guarantee the stable operation of all programs. Many modern applications will simply refuse to start or will work with errors when placed on a slow medium.

⚠️ Note: Forced transfer of system applications or critical services (messaging apps, banking applications) to SD-The card can lead to unstable operation of the smartphone and sudden closure of programs.

Using a memory card as internal memory

An alternative approach is Adoptable Storage, which allows you to format the card so that the system will consider it part of the internal drive, in which case the data is encrypted, and the card becomes unreadable on other devices without re-formatting. On the Redmi Note 7, this feature is often hidden, but sometimes available when you initially configure the phone.

If the system offers to format the card as internal memory, you can agree by saving the data beforehand. After that, the applications will automatically be installed on the map, freeing up space in the main partition. However, the speed of work can decrease, especially if you use a low-end card, which will affect the speed of the entire interface.

This method is suitable for users who install a lot of lightweight applications and are willing to put up with a potential decline in performance in order to increase the amount of space available. For games with heavy cache and graphics editors, it is better to leave internal memory free.

Cache cleanup and storage optimization

Even after transferring files, the system may show incorrect memory usage due to overgrown cache. Periodically use the built-in Cleanup tool available through the Security app, which allows you to delete temporary files, remnants of deleted applications and advertising debris that accumulates in the background.

You should also look at the.thumbnails folder in the hidden system directories, which stores thumbnails of all the photos and videos you've viewed, and it can be as small as a few gigabytes, and you can clean it through a conductor, including the display of hidden files, or with specialized thumbnails to clean up the thumbnail cache.

💡

Regularly cleaning the app cache in the Apps section → All Apps → Memory → Clean up helps free up to 1-2 GB of space without losing personal data.

Remember to check the Downloads and Recycle Bin section in the gallery. Deleted photos often stay in the cart for 30 days, continuing to take up space. Completely cleaning the cart is the final touch in the process of optimizing your Xiaomi disk space.
