How to use Xiaomi smartphone as a flash drive: all ways and settings

Xiaomi smartphones have long ceased to be just a means of communication, they have become full-fledged multimedia centers with tens of gigabytes of internal memory. But what if you want to quickly transfer files to your computer and there is no USB cable or external drive at hand? Connect Xiaomi as a way to USB-It's a memory drive that you can use as a flash drive, and it allows you to copy photos, videos, documents, and even run programs directly from your phone without taking up space on your PC's hard drive.

However, not all users know that it requires not only a physical USB connection to work properly, but also the correct configuration of the data protocol. Depending on the model (Redmi Note 12, POCO X5, Mi 11, etc.) and the version of MIUI, the process may be slightly different. In this article, we will discuss all the current ways of connecting, including MTP, PTP, OTG mode for working with other devices, and also solve typical problems like “computer does not see the phone” or “phone memory does not open”.

1. What connection modes does Xiaomi support?

When you connect Xiaomi to your computer via USB, the system suggests you choose one of the data protocols, each of which has its own purpose:

• 📁 MTP (Media Transfer Protocol - the main mode for file sharing, allows you to view and edit folders of the phone as a normal flash drive, but with some restrictions (for example, you can not format a partition).
• 📷 PTP (Picture Transfer Protocol - optimized for photo and video transfer, often used if MTP It does not work or you need compatibility with older versions of Windows.
• 🔌 USB-Modem – turns the phone into a source of Internet for PC (not suitable for working with files).
• 🔄 File Transfer (Android Auto) – a specialized mode for automotive multimedia systems.
• 🖥️ Midlink/HiSuite — protocol for Huawei proprietary software, but sometimes appears on Xiaomi (usually on older models).

Only MTP and PTP are suitable for using the phone as flash drives, and MTP is more versatile, since it allows you to work with all types of files, not only with media. Importantly, some models (Redmi 9A, POCO M3) can default to a charging mode that blocks data transfer, and you need to manually change it in the notification curtain.
