You put it in. SD-card in your Xiaomi Redmi, but Explorer (or other application) does not see files or ask for permission? MIUI, where the default system restricts access to external drives, the reasons can vary from incorrect formatting of the card to failures in security settings. In this article, we will discuss all working methods, from basic to advanced, including solutions for cases where the map is determined, but the files are not displayed.
Feature MIUI It uses its own permissions manager, which sometimes conflicts with standard Android settings, such as after a system update or reset, access to the system. SD-This map may be lost even for the built-in Xiaomi Explorer, and we will look not only at how to give permission, but also at how to avoid common mistakes, such as data loss when formatting a map in an inappropriate file system.
Why the Conductor Can't See SD-map on Xiaomi Redmi
Before you set up permissions, itโs important to understand the root of the problem. SD-map or block access to it:
- ๐น The card is not formatted or uses an incompatible file system (e.g., file system, NTFS instead FAT32/exFAT).

If the card is defined in settings (see Settings โ Storage) but Explorer doesnโt show files, the problem is probably the permissions. If the card doesnโt show at all, check it on another device or reformat it.
Method 1: Give permission through MIUI settings
The easiest method is to use the built-in MIUI tools. This is suitable if the card is visible in the system, but Explorer requests access or does not display files.

These commands force the Explorer to authorize external storage, and if access does not appear after the reboot, check if the settings have reset (sometimes MIUI blocks the changes).
