Modern smartphones Xiaomi, Redmi and Poco have a huge internal memory, but even it can run out at the most inopportune time. Often, there is a situation when you urgently need to transfer gigabytes of photos, movies or documents from your computer, and there is no cloud services or stable Internet at hand. USB-storage OTG.
The process of connecting external storage to a mobile device seems simple, but users often face a number of obstacles: the phone may not see the flash drive, require formatting, or refuse to read certain file formats, due to differences in file systems and the features of the MIUI or HyperOS shell.
In this article, we will discuss how to view the contents of the flash drive on your smartphone, we will look at the nuances of connection, choosing the right file manager and methods for solving common errors so that you can seamlessly work with data.
Checking OTG technology support on your device
Before you run for an adapter, you need to make sure that your smartphone is technically capable of working with external drives. The vast majority of modern Xiaomi models support the USB On-The-Go standard. This technology allows the mobile device to act as a host and supply power to plug-in gadgets.
However, having support doesn’t always mean that the feature is active by default or works correctly with all types of devices. Older models or budget segments of the Redmi line may have limitations on the current delivered through the port. If you try to connect an energy-intensive external hard drive without its own power, the phone may simply not detect it.
⚠️ Attention: Using substandard adapters can lead to voltage surges, which is dangerous for your smartphone's power controller.Always use certified accessories.
To quickly check compatibility, you can use specialized applications from Google Play that test the hardware of the device, but most often just plug in a flash drive and look at the reaction of the system. If there is a message about the connection in the notification curtain USB-The storage device means the hardware is in good condition.
Required adapters and cables for connection
The key element in the connection chain is the correct adapter. Standard charging ports in Xiaomi smartphones can be like Micro-USB (in older models) or USB Type-C drives, on the other hand, are usually full-size connectors. USB Type-A. They are required to connect OTG-cable.
When choosing an adapter, pay attention to bandwidth. For conventional flash drives, any adapter that supports the USB 2.0 standard will work. But if you plan to transfer large amounts of data from a fast USB 3.0 drive, you better buy a quality cable that supports high transfer rates, otherwise you will not see the declared performance.
There are several types of connections that should be considered:
- 🔌 Direct adapter: compact connector inserted directly into the phone port, easy to carry in a case, but can interfere with the use of the smartphone in horizontal mode.
- 🔗 Extension cable: gives more freedom to put your phone next to the flash drive.
- 💾 Dual Drive: a special device with two connectors (USB and Type-C/Lightning). No additional adapters are required and look aesthetically pleasing.
Metal adapters are better at removing heat that can occur during long-term data transfer, preventing the smartphone port from overheating.
💡
If you often work with flash drives, buy an adapter with an additional charging port, which will allow you to charge your phone and use external memory at the same time, saving battery power.
File Manager Configurement in MIUI and HyperOS
Once the flash drive is physically connected, the system must automatically launch the file application. Xiaomi smartphones have their own Explorer installed by default. It is quite functional, but sometimes users prefer third-party solutions for more subtle control.
To open the flash drive manually, look for the Explorer app on the desktop or in the Tools folder. The connected icon should appear on the side menu or at the top of the screen. USB-If you don't automatically open, pull the notification curtain down, and you'll see the "Connected" system notification. USB-The drive. Clicking on it will open up the files.
In some cases, especially when using third-party file managers like Total Commander or FX File Explorer, you may need to manually mount. You will need to go to the "USB" or "External Drives" section inside the application. The MIUI interface may request permission to access the external storage - it must be confirmed, otherwise you will not be able to read or write data.

Problems with formats: NTFS vs. FAT32 and exFAT
One of the most common reasons why Xiaomi’s smartphone doesn’t see the flash drive is file system incompatibility. Android initially works best with FAT32 and exFAT formats. However, many flash drives, especially those over 32GB, are formatted into the NTFS file system, which is native to Windows but isn’t always supported by Android out of the box.
If you see an error message when you connect, or if your phone suggests that you format the drive, it can't read the current data structure. The formatting will destroy all the files, so pre-copy them to your computer. Once formatted into a compatible format, the USB drive will become available.
Comparison of the main file systems for use with a smartphone:
| File system | Max. File size. | Compatibility with Android | Features |
|---|---|---|---|
| FAT32 | 4GB | Complete (100%) | Does not support files larger than 4GB, ideal for compatibility |
| exFAT | No restrictions. | High (on the new Xiaomi) | Optimal for high-volume flash drives and 4K video |
| NTFS | No restrictions. | Requires third-party software | The native Windows format is often not read without drivers |
| ext4 | No restrictions. | Only with Root rights. | Linux/Android system format not visible on Windows without plugins |
If you need to work with NTFS without formatting (for example, a flash drive contains a 10 GB movie that will not fit into FAT32), you will need special applications that allow you to mount NTFS partitions in a software way, although the read speed may be lower.

Problem Solving: The phone doesn't see the drive
When nothing happens after you connect, it's not uncommon. First, check the integrity of the cable and the adapter itself. Cheap Chinese adapters often fail or fail to meet the declared characteristics. Try connecting the USB drive through another adapter or to another phone to prevent the drive itself from breaking.
The second common cause is power shortage. If you plug in a volumetric external hard drive (HDD), It might not have enough power from the smartphone port. USB-A powered hub, solid state drives (SSD) And the usual flash drives usually do not cause problems.
It is also worth checking the settings. USB-Although this is rarely required to simply view files, sometimes resetting settings USB Helps. Go to Settings. → The phone. → Version. MIUI (Press 7 times to activate the developer mode, then in Advanced Settings → For developers, find the item "Configuration" USB Set the value "File Transfer (MTP)".
⚠️ Note: If the phone is writing "USB-The device is corrupted" or "Can't be used," don't ignore it.Perhaps the file system of the flash drive contains errors that can damage the data on the phone.
Sometimes the problem is contamination of the charging port. Carefully inspect the Type-C connector for dust or pile, which can prevent the adapter from contacting tightly. Cleaning with a soft brush often solves the problem of "falling off" connection.
Alternative ways to view files via PC
If you don't want to mess around with adapters, there's always the classic way to connect your smartphone to your computer as an external drive, so you can use your PC resources to manage files on the flash drive if it's inserted into your computer, or you can use your computer as a bridge.
To transfer files over the network, you can use the built-in Mi Drop function (now Xiaomi Share) or third-party utilities like FTP Server. FTP-server on your phone, you can go through Windows Explorer on the local network to the memory of your smartphone and copy the desired files without wires. USB connection, but very convenient for small transfers.
Another option is to use cloud storage integrated into the system: Google Drive, Yandex.Disk or Mi Cloud allows you to download a file from a flash drive (via a PC) and instantly download it to your phone, but this method requires a stable and preferably unlimited Internet connection.
💡
The fastest and most reliable way to transfer large amounts of data (movies, archives) is a direct connection through the Internet. OTG-Wireless methods are good for documents and photos, but slow for gigabytes of information.
