This problem is familiar to many brand users - especially after updating MIUI or resetting. In this article, we will discuss all possible ways to access the memory card on Xiaomi, including hidden folders, system settings and connecting to a PC.
It is important to understand: the path to files on SD-The card depends on the firmware version, smartphone model (for example, Redmi Note 12 or the other one). POCO X5 They may have different interfaces, and even from the card manufacturer (SanDisk, Samsung, Kingston).We will look at the universal methods that work on most Xiaomi devices, and also point out the typical errors that can cause the memory card to “missing” from view.

- 📁 ES Explorer: Shows hidden system folders, supports cloud storage.
- 🗂️ Solid Explorer: user-friendly interface with tabs, works with FTP and encrypted archives.
- 🔍 FX File Explorer: Lightweight and fast, suitable for older Xiaomi models (e.g. Redmi) 4X).
Instructions for Solid Explorer:
- Install the app from Google Play.
- Open it and give access to the storage.
- In the side menu, select Warehouse → SD-map.
- If the card is not visible, tap on the three-point menu → Settings → Show hidden files.
Third-party guides are also useful if you want to:
- 🔒 Move files between internal memory and SD-free-card MIUI.
- 📂 See system folders (for example, Android/obb play-off).
- 🔄 Create backups to the memory card directly.
