Owners of the Xiaomi Redmi 7 smartphone often face a lack of built-in storage, especially if the basic version of the device is only 32 GB. Overflowing memory slows down the system, prevents new applications from being installed, and critically, prevents the camera from taking new pictures. SD-map that allows you to expand the available volume several times without losing important data.
The process of moving media files does not require root rights or complex technical skills, but it has its own nuances in the shell of MIUI. In this article, we will discuss in detail the regular methods of transferring images, using a standard file manager and the hidden capabilities of the system to automate the process.
Before you start taking action, you need to make sure that the memory card is installed correctly and recognized by the system. If you just purchased the drive, it should be formatted, but remember that formatting will completely remove all data from the card. For working with photos, it is best to use Class 10 and higher drives to ensure high write speed.
Preparation of a memory card and installation in a slot
The first step is to physically install the drive, because without it, no further manipulation is possible. The Redmi 7 uses a combined tray, which means that you can install either two or more. SIM-You need a special key-clip that comes with the package, or a single SIM card and a memory card.
Carefully remove the tray from the end hole of the case and place the microSD card in the appropriate slot with metal contacts down. Note the shape of the card cutout - it should match the contour of the tray. Once the tray is installed back, the device will automatically scan the drive and prompt it to configure.
⚠️ Warning: Never remove a memory card during a data recording process or camera operation, this may cause file system damage and loss of photo archives.
The system can offer two options for using the drive: as a portable storage device or as part of internal memory. To transfer photos and videos, you should choose the first option, as it provides better compatibility with other devices and computers. Formatting takes a few seconds, after which the corresponding icon will appear in the notification curtain.
💡
Use memory cards up to 128GB for maximum stability, although the Redmi 7 officially supports up to 256GB, more capacious models can run slower.
Use of the standard "Conductor" application
The easiest and most reliable way to move existing photos is to use the built-in file manager, which is called Explorer in the MIUI shell and has a yellow icon with a folder, which allows you to work with the Android file structure without having to connect to a computer.
Open the app and go to Images or Internal Drive. You need to find the DCIM folder, which is the default one that saves your camera shots. Inside this folder is the Camera subfolder, where your photos are, select the files you want with a long press, or select All through the menu.
After selecting, click on the "copy" or "move" button in the bottom menu bar. The system will prompt you to select destination. SD-map (usually indicated as storage/emulated/0 For internal or card name for external. Create a new folder or select an existing one to save.
☑️ Pre-movement checks
The copying process can take time depending on the number and weight of files. During the operation, it is not recommended to switch between heavy applications so as not to load the Snapdragon 632 processor installed in Redmi 7. Once the process is complete, be sure to check for files in a new location before removing the originals.
Configure automatic saving to SD-map
To avoid wasting time on manual transfers in the future, you can set up your smartphone camera so that new images are saved immediately to an external drive, which is especially true for users who take a lot of photos and shoot videos in high resolution.
Go to the Camera app and click on the menu icon (three bars) in the upper right corner. Select Settings and scroll down to the Save section. Here you will see the Save to Save to the Settings button. SD-Activate it, and all new media files will be written directly to the external storage.
However, it should be noted that when activated, some system previews may still take up space in internal memory. In addition, the burst speed may decrease if the speed class of your memory card is not enough. For video recording in 1080p or 4K (if supported), high write speed is required.
| Parameter | Internal memory. | SD-card (Class 10) | SD-card (Class 4) |
|---|---|---|---|
| Reading speed | Tall. | Medium/High | Low. |
| Recording speed | Very high. | Medium | Low. |
| Stability | Maximum | Good. | Possible delays |
| Recommendation | System photo | Photos and videos | Only a photo. |
Work with Gallery and Hidden Albums
The Gallery app in Xiaomi offers a user-friendly interface for sorting, but it doesn't always correctly display the way you save files. If you've moved photos through the Explorer, they can disappear from the general view or appear as a separate album with the name of the folder.
To manage your albums, go to the Albums tab at the bottom of the screen, where you can create new folders, mix them up, and most importantly, hide them from prying eyes. The Hidden Album feature allows you to protect your personal photos with a password or fingerprint, and this data can also be moved to a memory card for security.
If you see duplicate images after transfer, check the display settings in the gallery. Sometimes the system caches thumbnails and the old paths to the files remain in the media database. Clearing the cache of the Gallery application through the smartphone settings will help update the list of available images.
It's important to understand the difference between moving a file and making a copy of it. When you're working with a gallery through a send or share menu, you often create a copy of the file and the original stays where it is.
⚠️ Note: When transferring hidden albums, make sure you copy not only visible files, but also hidden system folders that start from a dot, otherwise access to protected photos will be lost.
Cleaning up garbage and duplicates after transfer
Once you have moved gigabytes of photos, you may have tails in your internal memory — thumbnails, social media app cache, and temporary files — and the standard cleaning tool in the Security app will help you remove unnecessary debris.
Run the Security app, select Cleanup and wait until the scan is over. The system will prompt you to delete cache, advertising files and remnants of deleted applications. Be careful when cleaning the Big Files category so that you don't accidentally delete important documents that you haven't moved yet.
It's also worth checking the Thumbnails folder inside the DCIM directory. It stores gallery thumbnails, and it can grow to a few gigabytes in size. Deleting the contents of this folder is safe - the system will recreate the necessary thumbnails the next time the gallery opens, but it will free up valuable space right now.
What if the Thumbnails folder has grown again?
Possible problems and solutions
During operation, users may experience card read errors or sudden disappearance of files, most often due to improper extraction of the drive or a failure of the file system. If Redmi 7 stopped seeing the card, try restarting the device without removing the media.
If the problem persists, remove the card, paste it into your computer through a card reader, and check for errors with Windows. The file system must be formatted in FAT32 or exFAT for full compatibility with Android. NTFS is not supported without special drivers.
In rare cases, the problem lies in the oxidation of the tray contacts. SIM-Wipe the card contacts with a soft dry cloth and make sure there is no dust in the phone slot. Also make sure the card is securely fixed in the tray and does not dangle when shaking.
If the memory card is identified as damaged, do not rush to format it – first try to copy important data to the computer, as formatting will destroy the information irrevocably.
💡
Regular backup of important photos to the computer or the cloud is the only guarantee of data safety, since physical media tend to fail.
Additional cloud storage capabilities
While the memory card solves the problem of space shortage, it does not protect against physical loss or breakage of the smartphone itself. Xiaomi Cloud service or third-party solutions like Google Photos allow you to synchronize photos with the server.
Configure automatic uploading of photos to the cloud only via Wi-Fi, so as not to waste mobile traffic, this will create an additional copy of your archive. When combined with a memory card, you will get dual protection: fast local storage and remote backup.
Cloud services are also convenient when switching to a new phone, so you don't have to manually transfer files, just log in to your account, and all the photos are available in their original quality, which is especially true for owners of the Xiaomi ecosystem.
