Modern Xiaomi smartphones are equipped with impressive cameras that can create high-resolution images, but this inevitably leads to a quick filling of internal memory. Users often face a notification of a shortage of space, which prevents the installation of updates or new applications, making the issue of backup critical.
There are several proven ways to solve this problem, each of which has its own advantages depending on your situation and the availability of additional accessories at hand. USB-adapter OTG, But if you don't have a dedicated cable, you can always use your computer as an intermediate or use cloud storage, although the latter requires a stable Internet connection.
In this article, we will take a look at all the options you can choose the best one for yourself and forget about the problem of overcrowded storage. We will look at the nuances of the Android file system, the features of the MIUI interface and give practical tips on how to organize files. Get ready to turn the chaos in the gallery into an ordered archive, available at any time.
Preparation of equipment and compatibility check
Before you start directly copying files, you need to make sure that your hardware is ready to go. Most modern Xiaomi smartphones support USB OTG (On-The-Go) technology, which allows the device to act as a host for the periphery. However, if your gadget is several years old, it is worth checking the model specifications on the official website or in the instructions in advance to avoid disappointment in the process.
You'll need the flash drive itself and perhaps a special adapter if the connectors don't match. Newer models use the USB Type-C standard, whereas many older drives have a classic Type-A connector. To connect these two worlds, you'll need a compact OTG adapter that you can buy from any electronics store.
⚠️ Warning: Make sure your flash drive is formatted in the file system FAT32 or exFAT. File system. NTFS, Often used on Windows computers, it may not be readable by a smartphone without installing additional drivers or applications.
Smartphones may have limits on the maximum amount of external memory they support, although modern Xiaomi flagships usually work with flash drives up to 256 GB or higher without any problems. If you use a very old, large storage device, the phone may simply not see it or offer to format it, which will lead to the deletion of all data.
💡
For frequent work with flash drives, it is recommended to purchase a universal drive with two connectors (Type-C and Type-A), which will save you from the need to carry additional adapters with you.
Direct transmission via USB OTG adapter
This is the most convenient and autonomous way, without having to have a computer or access to the Internet. OTG-cable to the smartphone charging socket, Android must automatically recognize the new device. Usually, the corresponding icon appears in the notification curtain. USB-The storage device, and a new partition appears in the file manager.
To manage files in the MIUI shell, you use the built-in Explorer (or File Manager) application. Open it and find your flash drive in the list of available storages, which can be displayed as "USB storage" or by manufacturer name. Go to the DCIM → Camera folder, where all your photos are stored by default.
☑️ Algorithm of copying through OTG
You can select multiple photos in the MIUI interface by swiping your finger across the screen or using the "Select All" button on the menu. After highlighting, click Copy or Move at the bottom of the screen. It's important to understand the difference: copying will leave the originals on the phone, and moving them away from there, freeing up space.
Next, go to the root directory of your flash drive or create a new folder there for convenience, for example, calling it"Photos_Backup". Press the Insert button. The speed of the process will depend on the speed class of your flash drive and the number of files transferred. Do not remove the drive before the operation is completed, so as not to damage the data.
⚠️ Note: If the copying process is slow or stalled, you may be trying to transfer too many files at once. 500-1000 photo.
Using the computer as an intermediate
If you don't. OTG-A cable or flash drive is large and requires power that the phone can't provide, and the best option is to use a PC or laptop, which is also convenient if you want to re-furbish archives for several years, because it's easier to navigate the folder structure on a large screen. First, connect your smartphone to your computer through USB-cable, preferably original, to ensure a stable data rate.
You'll see a request for USB mode on your phone. Select File Transfer (MTP). On your computer, open "My Computer," find your Xiaomi device there, and open internal memory. Find the DCIM folder, then the Camera, and copy the photos to your computer's hard drive.
After the photos are on the computer, remove the phone and connect the flash drive directly to the computer. USB-Create a destinazione folder on your flash drive and drag the saved images there. This two-step process may seem long, but it guarantees maximum compatibility and allows you to audit files in parallel, removing blurred or failed frames.
What to do if your computer can’t see your phone?
When dealing with large amounts of data through a computer, it is important not to interrupt the connection abruptly. Use secure device extraction on Windows or macOS before physically disabling the flash drive or phone, which will prevent file system logic errors and loss of the last recorded files.
Working with a file manager and organizing data
Once you've mastered the basic techniques of transferring, it's worth thinking about organizing your digital archive. Chaotic dumping thousands of photos into one folder on a flash drive after a while will turn finding the right image into torture. The Xiaomi Explorer built-in allows you to sort files by date, size or name, which makes navigation much easier.
It's recommended that you create a folder structure on your flash drive that matches years or events, for example, create an Archive root folder, 2023, 2026 folders inside it, and then leave it, birthday, work, and this hierarchy will allow you to quickly find the memories you want in the future, even if you're looking at files from another device that doesn't support smart tag sorting.
| Type of sorting | Advantages | Deficiencies |
|---|---|---|
| By date (Year/Month) | Logical chronology, easy to find photos by time | It is difficult to find a specific event if you do not remember the date. |
| On the ground. | Convenient for finding thematic photos | It is difficult to create folders manually |
| Alphabetical | Quick search by file name | It's pointless for a photo with names like this. IMG_001.jpg |
Remember to check the integrity of the data on the flash drive periodically. External drives, especially cheap models, can lose information over time or with frequent use. Once every six months, it makes sense to connect the flash drive to the computer and run error checks or just visually evaluate the ability to open files.
Alternative methods: Cloud and Wi-Fi transmission
While the issue was porting to a flash drive, you can't ignore wireless methods, which can be a great alternative or add-on: Google Photos or Xiaomi Cloud allows you to automatically upload images to the Internet. After that, you can go from your computer to the web version of the cloud, download the archive and write it to a flash drive. This is convenient if the physical port of the phone is damaged.
Another interesting option is to use Wi-Fi applications like Send Anywhere or Windows Sharing, which allow you to transfer photos to a PC wirelessly and then transfer them to a flash drive. 5GHz Wi-Fi speeds can be even faster than the old USB 2.0.
But wireless technologies have a significant downside: they depend on Internet speed and data plans; downloading hundreds of gigabytes of photos can take hours or run out of traffic; so for a one-time full backup of internal memory, wired connection via OTG or cable to a PC remains the leader in speed and reliability.
If you do choose the cloud path, make sure that the download quality is set in Original, not Save Space, if you care about detailing your images. Google compressed photos take up less space, but when printed in large formats can look worse than the original.
Problem Solving and Diagnosing Errors
Users can experience a variety of errors during the copying process, from the banal “not enough space” to messages about file corruption. If the phone says that the file is too large for the file system, then your USB drive is formatted in FAT32, which does not support files larger than 4 GB. This is true if you are downloading not only photos, but also long videos in 4K.
To solve the problem with the file size, the flash drive must be reformatted to exFAT or NTFS. You can do this on your computer: right-click on the disk, select Format and specify the desired file system. Remember that formatting will completely delete all data from the drive, so save it in advance.
⚠️ Warning: When formatting a flash drive on your computer, select the default cluster size. Changing this option unnecessarily can reduce the performance of the drive when working with a smartphone.
Another common problem is a sudden interruption of copying, which can be due to overheating of the phone, poor contact in the connector or energy-saving MIUI settings that "kill" the background processes. Go to the battery settings and allow Explorer to operate in the background without restrictions.
If neither of these methods works, try restarting your smartphone with the flash drive connected. USB-Android hosts can crash, and a simple reboot restores the port to normal operation. It’s also worth checking if Charging Only is enabled in hidden settings. USB (available through the developer menu).
💡
The most reliable way to save photos is combined: store current pictures in the cloud, and keep the full archive on a physical flash drive, which must be updated periodically.
