Modern smartphones Xiaomi, Redmi and POCO Often lacking a memory expansion slot, which forces users to switch to cloud storage or external drives. SD-If you have a new phone after you have a new one, the issue of porting the archive of photos becomes critical.The internal memory of the device fills up instantly, especially if you are shooting in high resolution or format. RAW.
The migration process does not require a deep technical knowledge, but it requires care to avoid losing valuable staff. There are several proven ways to do this, from using built-in tools to connecting an external card reader, the choice of method depends on the availability of space on the device itself and the type of memory card used.
In this guide, we will discuss all the current options for copying media files. You will learn how to format the drive correctly, what MIUI or HyperOS tools to use to work with files, and how to avoid common errors when reading external media.
Preparation of memory card and smartphone for work
Before you start copying, you need to make sure that the memory card is correct and formatted correctly. Most often you use the FAT32 or exFAT file system, which can be easily read by the Android operating system. If the card is new, the system may suggest formatting it immediately after installation, but it is better to do this in advance for transfer to the computer or through an adapter.
MicroSD phones are more fortunate to have the ability to insert the card directly into the device, but if your Xiaomi smartphone does not support memory expansion, you will need a special device. USB-cardreader OTG. This compact device plugs into the charging connector and allows the phone to see the card as an external one. USB-accumulator.
- πΈ Make sure there are no physically damaged areas on the memory card that can interrupt the reading process.
- π Charge your smartphone to a minimum 40-50%, Active work with files and screen highlighting consume energy.
- π Check card reader compatibility: for large data volumes (over 32 GB) you need an adapter with support USB 3.0.
β οΈ Note: If there is important data on the memory card that is not copied elsewhere, do not agree to the formatting that the system can offer when you first connect until you make a backup copy.
It is also important to check whether USB debugging is enabled, although it is not usually required to simply copy files, and the main task at this stage is to ensure a stable physical connection between the carrier and the phone's processor.
Using Built-in Explorer to Copy Files
The easiest and fastest way to transfer photos is to use the regular Explorer app, which is preinstalled on all Xiaomi devices. This tool can work with external drives, defining them as separate drives. The program interface is intuitive and allows you to copy, move and delete files in several touches.
After connecting the memory card through the slot or OTG-Adapter, open the app. In the list of available storage, you'll see internal memory and external storage. USB-storage SD-You need to go to the photo folder, which is usually on the way. DCIM/Camera or Pictures, select the desired files and select the action "Copy" or "MoveΒ».
βοΈ Pre-copying check
When working with large amounts of data, the system may request permission to access files. You must confirm this action, otherwise the operation will not begin. Once the process is complete, it is recommended to check the integrity of the files by opening several random images in the gallery.
- π To speed up your search, use sorting by date of change or file size in the Explorer menu.
- π Select files in groups by holding your finger on one of them and swiping across the screen to cover the range.
- ποΈ Do not delete the originals from your memory card immediately until you make sure that all photos have opened on your phone.
The standard file manager feature in the MIUI shell also allows you to create ZIP archives directly on the device, which is convenient for grouping old photos by months or events before sending them to the cloud.
Transfer data through computer and card reader
If you canβt avoid a direct connection or need to throw hundreds of gigabytes of information, the most reliable way to use a computer is to ensure maximum data speed and stability of the connection, you will need a PC or laptop with installed drivers for Xiaomi (usually installed automatically) and a card reader.
Connect your phone to your computer through USB-You'll see a notification on your smartphone screen about the mode of connection. You need to select the mode "File transferΒ» (MTP). After that, two devices will appear in My Computer: the phoneβs internal memory and a memory card (if it is inserted into the phone) or an external card reader.
What to do if your computer canβt see your phone?
The process of copying to a PC is done by Drag-and-Drop, and you just open the memory card window, copy the photo folders, and paste them into the phone's memory, so you can easily control the process and interrupt it at any time without losing data.
| Parameter | Through the Conductor (OTG) | Through the Computer (USB) | Through the Cloud (Wi-Fi) |
|---|---|---|---|
| Speed. | High (depends on USB) | Maximum | Low/Mediocre |
| Stability | Medium | Tall. | Depends on the router. |
| Equipment required | Cardreader + OTG | PC + Cable | Internet |
| Battery consumption | Medium. | Low (charging is coming) | High-pitched |
Once you have finished copying, safely remove the device. In Windows, this is done via a tray in the lower right corner (βSecure Device Removalβ), and on the phone through settings or USB connection notification.
Alternative methods: Cloud services and Wi-Fi
When you don't have a card reader or a computer, wireless technologies come to the rescue. Google Photos automatically syncs images if the card is connected to an OTG and the phone recognizes it, but most cloud services only work with internal memory, but there are intermediary applications.
Apps like Send Anywhere or Xender let you transfer files between devices or from an external drive to your phone over Wi-Fi Direct, you insert a card into a card reader, connect it to your phone, open the file manager inside the transmitter app, and send the photo to your destination folder. The speed depends on the Wi-Fi standard and the distance.
Using cloud storage (Google Drive, Yandex Disk, Mi Cloud) is convenient because photos are stored forever and accessible from any device, but to initially download large volumes from a memory card, you will need stable and fast Internet, which is not always possible.
- βοΈ Google Photos can compress quality when downloading free, check the download quality settings.
- πΆ To transfer large files over Wi-Fi, make sure both devices are on the same 5GHz network.
- π When using public Wi-Fi networks to transfer personal photos VPN-linkage.
This method is good for regular backup of small portions of photos, but it can take too long to migrate the entire archive from a memory card, and it consumes a significant amount of traffic if you donβt have unlimited rates.
Solving reading problems SD-map
It's not always a smooth process. Often, users are faced with the fact that Xiaomi phone does not see the memory card or gives a format error. One of the common reasons is the NTFS file system, which Android does not support natively without root rights or special drivers. The card needs to be reformatted to FAT32 or exFAT.
Another problem is that the file table is damaged after being improperly extracted from another device, in which case the system may suggest that you restore files or format the drive. If you need a photo urgently, try connecting the card to your PC and running error checks through the disk properties.
β οΈ Note: Formatting a memory card will completely destroy all data on it. Only do this if you have already copied the photo or do not need it.
Also worth noting is the power of the USB port: Some older card readers consume more power than the phone port can give, especially if the smartphone battery is drained, in which case the phone can periodically turn off the drive, interrupting the copy.

Use the DiskDigger app or similar tools from Google Play if you want to recover deleted photos from your memory card before formatting, and they can find traces of files even after cleaning.
If nothing works, try restarting your phone with the drive connected. Sometimes the USB driver needs to be re-initialized to correctly identify the device, and check if the phone connector or the contacts of the memory card itself are contaminated.
Optimizing Photo Storage After Transfer
Once you've successfully transferred a photo from a memory card to a Xiaomi phone, it's worth thinking about organizing this data set. The gallery can run slowly if it contains tens of thousands of images.
The built-in MIUI tools allow you to hide albums, create select collections, and automatically group photos by person or location, which greatly speeds up navigation, and you can set up automatic cleaning of screenshots and similar shots.
π‘
Regular cleaning of the gallery cache and removing duplicates free up to 15% of internal memory and speed up the smartphone.
Remember that the internal memory of the phone works faster than the external card, so storing frequently used photos and videos on the built-in drive will have a positive impact on the speed of opening the gallery and the work of artificial intelligence in image processing.
