How to delete folder on Xiaomi: safe ways and risks

Removing folders on Xiaomi devices is a challenge that both beginners and experienced users face. Unlike standard Android smartphones, MIUI firmware has features: hidden system directories, secure micro-G files and duplicate folders from embedded services. Mistakes can lead to malfunctioning of the gadget, loss of photos or even “bricking” the device.

In this article, we will discuss which folders can be deleted without risk and which ones are strictly forbidden to touch. We will talk about built-in MIUI tools, third-party file managers with root rights, and work through ADB for advanced users, and we will focus on the recovery of deleted data and the typical errors that owners of Redmi, POCO and Mi make.

What folders on Xiaomi can be deleted and which ones can not

Before you start cleaning, it is important to understand the hierarchy of folders in MIUI, which can be divided into three categories:

• 📁 Custom folders – created by you or applications (e.g. Download, DCIM/Camera). They can be deleted without consequences if they do not contain important data.
• 🛡️ System folders MIUI — catalogue /miui, /MIUI/Theme or /Android/obb. Removing some of them can disrupt themes, widgets, or games.
• ⚠️ Critical system folders — /system, /data, /vendor. Changes without root rights or through ADB almost always leads to failure.

Particular care should be taken with folders related to:

• 📱 PO Updates — /cache or /MIUI/OTA. Deleting files from here may interrupt the update process.
• 🔒 Safety — /MIUI/Backup (backup copies) or /Android/data/com.miui.securitycenter (antivirus).
• 🎵 Multimedia — /MIUI/Music or /Android/media. This is where the player metadata is stored.

⚠️ Attention: Folder /MIUI/Extra It contains files for recovery after reset, and deleting it can make it harder to return to factory settings.

If you are not sure about the directory’s purpose, use Files by Google or Solid Explorer to tell you which files are safe to delete. It’s also helpful to pre-restore via Settings → About Phone → Backup.

Method 1: Delete via standard MIUI file manager

The easiest method is to use the built-in Explorer (or Files in newer versions of MIUI) which requires no additional rights and is suitable for deleting user data:

1. Open the Files app (the folder icon on the desktop).
2. Go to the Device or Internal Memory section.
3. Find the folder you want to delete and hold the name to highlight.
4. Click on the basket icon (or select Remove from the menu).

Limitations of the method:

• 🚫 You can not delete system folders (the button Remove will be inactive).
• 🔄 Deleted files enter the Recycle Bin and take up space until cleaned.
• 📂 No hidden folders (e.g.,.thumbnails with sketches) are displayed).

To enable the display of hidden files:

1. In the MIUI conductor, tap three points in the upper right corner.
2. Select Settings → Show hidden files.

Method 2: Using ADB to remove protected folders

If the standard manager fails (for example, the /MIUI/Theme folder is not deleted), you can use Android Debug Bridge (ADB), which requires connecting to a PC and enabling debugging over USB.

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version. Go back to Settings → Additional → Developer. Turn on USB Debugging.
2. Connect your smartphone to your PC and confirm your trust in your computer.
3. Open the command prompt (Windows) or terminal (macOS/Linux) and type: adb devices Make sure the device is defined.
4. To delete the folder, use the command: adb shell rm -rf /sdcard/For example, for the folder OldThemes: adb shell rm -rf /sdcard/MIUI/Theme/OldThemes

⚠️ Attention: Command rm -rf deletes files irrevocably, bypassing the basket. Error on the way (for example, rm) -rf /sdcard/ without specifying the folder) can erase all data on the device!

Advantages of ADB:

• ✅ It works even with protected folders (if you have rights).
• ✅ It does not require root access for most operations.
• ✅ Allows you to delete files that are blocked MIUI.

Disadvantages:

• ❌ Requires a connection to the PC.
• ❌ Dangerous when incorrectly entering commands.
• ❌ Not all folders are available without root (for example, /data/data/).

Method 3: Root rights and third-party file managers

You need root rights to have full control of the file system, they give you access to the system folders, but they give you no warranty and increase the risk of failure. If you're ready, follow the instructions:

Popular Root Support Managers:

• 📂 Solid Explorer – intuitive interface, support for cloud storage.
• 🛠️ FX File Explorer - built-in FTP-server.
• 🔧 Root Browser – Specialized for Root Browser.

How to delete a folder through Solid Explorer:

1. Open the application and provide root access when requested.
2. Go to the root directory (/).
3. Find the folder you want (e.g. /data/app to remove application residues).
4. Keep your finger on the folder. → Delete.

After working with root rights, it is recommended:

• 🔄 Reset the device.
• 🛡️ Check the integrity of system files through Settings → The phone. → System check (if available).
• 📱 Make a backup copy through TWRP (if established).

💡

Before obtaining root rights, check if your Xiaomi model has custom recovery (TWRP) on the site [twrp.me](https://twrp.me/). Without it, recovery from a crash will not be possible.

How to Recover a Randomly Deleted Folder

Common Mistakes and How to Avoid Them

Even experienced users make mistakes when working with files on Xiaomi.

1. Delete /Android/data folder without backup

It stores application data (save games, messaging settings) and you have to reconfigure everything after cleaning, so you can use Titanium Backup for selective backup.

2. Clean /MIUI/Backup before discharge

This folder contains backups of SMS, calls and applications, and without it, recovery from resets will be incomplete. Solution: copy it to your PC before cleaning.

3.Use of rm -rf/ in ADB

This command will delete ALL of the device's contents, including the system files, and only restore it through a complete flashing, solution: always check the path before executing the command.

4. Deletion of folders.android_secure or estrongs

These are service directories for protected data (like app licenses) that could disrupt Google Play purchases, so don't touch folders that start with a dot.

5. Ignoring access rights

Some folders (e.g. /data/dalvik-cache) are protected from change, and trying to delete them without root will lead to an error. Solution: use adb shell su to enhance rights.

💡

Before any manipulation of system folders, disable synchronization with Mi Account (Settings → Accounts → Mi Account → Synchronization).
