Owners of Xiaomi Redmi Note series smartphones often face a situation where the Android security system blocks the access of applications to external storage. This is not a mistake, but a regular data protection feature, which, however, can interfere with the normal operation of file managers or photo editors. Understanding how to properly allow access to SD-The card will be the key to the full use of multimedia capabilities of your device.
In modern versions of the MIUI shell and the Android operating system, the rights process has become more stringent, requiring the user to take additional steps. You do not need to be a programmer, but it is important to carefully monitor the notifications that appear on the screen. Ignoring these requests leads to the gallery not seeing new pictures, and the music player refuses to scan the tracks.
In this article, we will explore all the nuances of interaction with the file system, from the initial installation of the map to the solution of complex conflicts of access rights, we will examine why the system restricts the actions of programs and how to safely circumvent these restrictions for personal use.
Primary configuration and formatting of the drive
Before requiring applications to access files, you need to make sure that the operating system itself correctly recognized the physical media. When you first install the memory card, Xiaomi will offer you to choose one of two use cases: as a portable storage or as part of internal memory.
If you choose to format for internal memory, the system will encrypt the card, and it will be available only on that particular device. In portable storage mode, files remain readable on other gadgets, but access rights are regulated more strictly. The initialization process takes from 30 seconds to several minutes depending on the storage volume.
⚠️ Attention: The formatting process will completely destroy all the data on the map. Be sure to back up important information on your computer before starting the procedure.
Once formatted, the system will automatically create the standard folder structure required for Android to work, which will house directories for screenshots, downloads and media of applications, and without the correct folder structure, even if you have access rights, programs may not work properly.

Use U3 or V30 speed memory cards to record high-resolution video to avoid sound and image dissynchronization.
The permission mechanism in Android and MIUI
Starting with Android 11 and in current MIUI builds 12, 13 and 14, Google has implemented a Scoped Storage policy, which means that apps no longer have automatic access to the entire file system by default. Every application must now request permission from the user explicitly, and this request is often ignored or blocked by the interface.
When you open a file manager or explorer, you may see a message that says that access to the storage is restricted, not a failure, but a security mechanism to prevent malware from stealing data. However, legitimate applications such as VLC Player or MX Player require full access to scan the library.
Redmi Note owners should be aware that the MIUI shell adds an extra layer of protection on top of standard Android, which is manifested in the form of countdown timer pop-ups that require confirmation of actions. If you do not have time to press the confirmation button, the request will be canceled by the security system.
Step-by-step instruction: granting rights through a conductor
The most common scenario that requires user intervention occurs when you try to open a folder on the SD-When a dialog box appears on the screen with the text "Files Access Required" or "Storage Access" on the screen, the algorithm of actions should be as follows.
In the window that appears, you need to click the "OK" or "Allow" button, and then the system file management window will open, where your root directory will be displayed. SD-Often, a blue button appears at the bottom of the screen that says "Use this folder" or "Use this folder".
It's critical that you don't just select a folder, but you confirm the choice in the second window. You click "Use this folder" and you click on another pop-up warning from Android, and it says that the app will access all the files in that folder and subfolders. You need to click "Allow".
☑️ Algorithm for obtaining rights
If you don't get access after that, you may need to manually select a path in your internal settings, so go to the settings of the app itself, find the "Storage" or "File Path" section, and specify SD-Repeat the card by repeating the confirmation procedure.
Solving Access Issues for Specific Applications
Sometimes the standard procedure doesn’t work for specific applications, especially if they were installed before the new Android security policies were implemented. In such cases, you need to manually check the permission settings in the smartphone menu. Go to Settings → Apps → All apps and find the desired program.
From the menu of the selected application, select "Permissions" or "Rights." Find the section related to files and multimedia. There may be several options: "Only during use", "Always" or "Request every time". SD-The card recommends you to choose the option always or full access to multimedia.
Special attention should be paid to cleaning applications and antiviruses. On Xiaomi devices, they often have extended rights, but can block access to other programs.
Why do some apps still not see files?
It is also worth checking whether the application includes a mode "Memory Protection" or a similar feature that can isolate the application from external memory for the sake of security. MIUI often solves the problem.
Table of error codes and solution methods
When working with external drives, users can encounter various error messages. Understanding the essence of the error allows you to quickly find a solution without resorting to a complete reset of the smartphone settings.
| Type of error | Probable cause | Method of decision |
|---|---|---|
| SD-map damaged | NTFS or exFAT file system is not supported | Formatting in FAT32 via PC |
| Access denied | Lack of rights to read the root directory | Re-granting rights through a conductor |
| File won't open. | The application is not entitled to record | Change of rights in the settings of the application |
| Map not determined | Poor contact or physical injury | Removal and re-installation of the card |
It’s important to note that the file system plays a key role: Android prefers FAT32 or exFAT. If your card is formatted in NTFS (Windows standard), the phone can only see it as ReadOnly (read-only), which will prevent apps from creating new files or cache there.
💡
The correct file system (exFAT/FAT32) is more important than access rights, because without it, the system simply cannot read data from the media.
Use of Special Access Protocols (SAF)
To get around the constraints, Google has implemented the Storage Access Framework (SAF), a mechanism that allows applications to work with files without direct access to the entire file system. When an application requests access via SAF, you see the standard Android file selection interface, not the application interface.
Some advanced file managers, such as Solid Explorer or FX File Explorer, which can work with SAF More efficient than a standard conductor MIUI. They can request access to everything. SD-map immediately using system gateways, which eliminates the need to confirm access for each folder separately.
If standard methods fail to allow access, install a specialized plugin or update the Access to Documents component in the Google Play Store. Sometimes the problem lies in an outdated system module responsible for interaction with files.
⚠️ Note: Be careful when installing plugins to work with the file system from unverified sources.They may have too broad rights and access your personal data.
