Xiaomi and Redmi smartphone owners often face a situation where the built-in storage is overflowing and the system insists on freeing up space, especially for models with limited memory, where every gigabyte counts. Internal memory is quickly consumed not only due to applications, but also due to high-quality images that take up a significant amount of space.
Moving media to an external medium is the most effective solution for extending the life of a device without buying a new one. MIUI offers flexible tools for managing files, allowing you to manually or automatically move content to a MicroSD.
In this article, we will look at all the available ways to migrate data, from using a standard conductor to advanced camera settings, learn how to format the drive correctly and avoid common errors that can lead to data loss.
Preparation of memory card for work in the Android system
Before you start copying files, you need to make sure that the external drive is correctly defined by the system. Formatting is a must for new cards or those used in other devices. Insert the MicroSD into the slot (usually combined with a tray for the second one). SIM-maps) and wait for notifications in the notification curtain.
The system can suggest using the card as an internal storage device or as a portable medium, and the second option is better for transferring photos, as this will make it easy to extract the card and read it on a computer or other phone.
Go to settings to check the status of the drive. Open Settings. → Storage and find the section associated with SD-If the system says that the card is damaged or requires formatting, agree, but remember: all data on the map will be deleted without the possibility of recovery.
💡
Use UHS-I (U1) or higher speed memory cards to record high-resolution video to avoid delays and frame skips when shooting.
Once successfully prepared, the system will assign the card a letter or ID and it will be available for recording. Make sure that the "Use as portable storage" mode is selected in the settings if you plan to change devices frequently.
⚠️ Note: Do not remove the memory card during the process of writing or reading data.This can damage the file system and lose some of the photos, even if the transfer is seemingly completed.
Using a standard conductor to move files
The most reliable and intuitive way to migrate existing images is to use the built-in file manager, which is called Explorer in the MIUI shell and has a user-friendly tab interface. Open the application and go to the Internal Drive tab.
You need to find the folder where the default photos are stored, usually a DCIM/Camera or Pictures directory, select the files you want with a long press or select "Select all" from the control menu.
Once highlighted, click on Copy or Move. The difference between these actions is significant: copying will leave the originals in place, taking up double the volume, and moving will simply change the path to the files, freeing up space.
- 📁 Click "Select All" for a Mass File Operation.
- 📂 Go to the root SD-maps via navigation menu.
- 💾 Click "Insert" to complete the transfer operation.
The process can take time depending on the number and weight of files, the progress bar will show the status of execution, if you interrupt the process, the files may remain damaged or moved only partially.
☑️ Pre-transfer check
Set up automatic photo saving on SD-map
So you can't manually transfer photos every time, you can set the camera up to immediately save the images to an external medium, which eliminates the need to constantly monitor the internal memory.
Open the Camera app and click on the menu icon (three bars or gears) in the upper right corner. In the settings list, find the item "Save on" SD-Map" or "Path of Preservation." Activate the switch.
It is worth noting that on some Xiaomi models with a very new version of Android, this feature may be hidden or missing due to system security limitations, in which case you will have to use manual movement or third-party applications.
Why did the SD save setting disappear?
Once you turn on the function, take a test shot and check its location through the conductor. The path should lead to a folder on the external drive, not in the internal memory.
Using an external map for shooting can slightly reduce the speed of serial shooting if the card has a low write speed.
⚠️ Note: When shooting video in resolution 4K or 8K It is strongly recommended to use internal memory, as memory cards may not provide sufficient bitrate speed, which will cause the recording to stop.
Transfer of folders of messengers and social networks
A significant portion of the memory is not only the gallery photos, but also the images received on WhatsApp, Telegram or Viber, which are often stored in deep directories of internal storage.
To move them, use a Explorer. Find the Android/media folder (or just the root folder of the app in older versions of Android). Inside, you'll see folders with the names of messengers.
Select folders with media files (usually called Media, Images or Video) and move them to the memory card, then in the settings of the messenger itself, you can specify a new path to the folder if the application supports this feature, or leave the files simply as an archive.
- 📱 Find the file. WhatsApp/Media internal storage.
- 🖼️ Select WhatsApp Images and WhatsApp Video folders.
- 🔄 Move them to the root SD-map or folder created by the Archive».
Regularly cleaning the messenger cache and transferring heavy video files keep the system on track, especially for budget models where RAM is also limited.
💡
Moving messenger folders frees up the most space, as video messages and chat pictures often weigh more than your personal photos.
Comparison of copying and moving methods
Different users prefer different approaches to organizing data, some like to keep everything in hand in internal memory, others like to archive old images, and understanding the differences between methods will help you choose the best one.
The table below compares the core characteristics of internal and external memory in Xiaomi’s ecosystem to help you make an informed decision.
| Parameter | Internal memory. | SD-map | Cloud services |
|---|---|---|---|
| Reading speed | High (UFS) | Medium (depending on class) | Depends on the Internet. |
| Reliability | Tall. | Medium (risk of loss in case of breakdown) | Tall. |
| Availability | Only on the device. | Any device with a card reader. | Wherever there is a network |
| Cost | Included in the phone price | Low (card purchase) | Monthly subscription |
The ideal strategy is a combination one: keep your current photos on a map for quick access, and duplicate your most important images to the cloud. Backup is never superfluous.
Remember that the speed of the gallery when viewing thousands of photos on the SD-The card may be lower than when viewing files in internal storage due to speed limits of reading successive blocks.
Possible problems and ways to solve them
When transferring files, users may encounter various errors, such as "File too big" or "copy error," most often associated with the card's file system.
If the card is formatted in FAT32, you can not write a file larger than 4 GB to it. To solve the problem, format the card in exFAT via a computer or smartphone menu.
Another common problem is hidden files or indexing errors, and if you've moved photos but you can't see them in the gallery, try rebooting your device, and the system has to scan the media space again.
- ❌ No Access Error: Check the permissions for the Explorer application.
- 🔄 The file is not copied: it may be corrupted or otherwise occupied by another process.
- 🔍 Photos missing: check the hidden folder.Trash or basket in the gallery.
Sometimes cleaning the Media Scanner app cache in the application settings helps, and this will force you to re-scan all the directories and update the gallery database.
⚠️ Note: If a memory card constantly emits reading errors or requires formatting every few days, it may be physically damaged.
