What folders can be removed on Xiaomi Redmi Note 8 Pro: secure memory cleaning

Owners of Xiaomi Redmi Note 8 Pro sooner or later face a lack of internal memory, despite the stated 64/128 GB. The MIUI system creates dozens of service folders, the cache of applications grows to giant sizes, and the “garbage” after updates takes precious megabytes. But what folders can be removed without the risk of turning a smartphone into a “brick”, and which ones can not be touched categorically?

This article will help you understand which directories in Redmi Note 8 Pro memory are safe to clean, how to distinguish system files from junk, and what tools to use to do so. We will analyze the folder structure in /storage/emulated/0/, deal with the MIUI cache, and give clear instructions — with warnings about possible consequences. Importantly, some operations require root rights, but most methods work without them.

Before you start cleaning, remember that removing the MIUI or Android folder in the root directory will cause the system to crash — the phone will not turn on even in recovery mode. But the game cache, temporary messenger files or duplicate photos can be safely deleted. Next, detailed analysis.

The memory structure of Redmi Note 8 Pro: which folders are responsible for what

Internal memory Redmi Note 8 Pro is organized according to the standard for Android scheme, but with the features of MIUI. All user files are stored in the directory /storage/emulated/0/ (also known as /sdcard/), and system - in /data/ and /system/. Access to the latter without root is limited.

The main directories you will see in the file manager are:

• 📁 DCIM — Photos and video from the camera (including screenshots in the Screenshots subfolder).
• 🎵 Music, Movies, Pictures – Media files added by the user.
• 📱 Android – application data (cache, settings, OBB-game-play).
• 🔧 MIUI — service shell files (themes, wallpaper, log files).
• 🗑️ Download – downloads from the browser and messengers.
• 📂 Bluetooth, Notifications – Temporary Data Transfer Files.

The heaviest folders on the Redmi Note 8 Pro are usually Android/data (game and social media cache), MIUI/theme (downloaded themes) and DCIM/.thumbnails (miniatures), but not all of them can be erased.

What folders can be deleted without consequences

Let's start with the good news: some folders can be cleaned without damaging the system, and the key is not to delete the directories themselves (like DCIM or Download), but only their contents. Here's a list of safe directories to clean:

• 🧹 Cash app: Android/data/*/cache — It stores temporary files of games and programs, and once the applications are cleaned, they'll just recreate the cache the next time they run.
• 🖼️ Miniatures photo: DCIM/.thumbnails — Removing images from the imagery will save you up to 500 MB.
• 🎨 Unnecessary topics MIUI: MIUI/theme — Downloaded wallpaper and styles. Systemic themes don't need to be touched!
• 📥 Downloads: Download – here usually accumulates garbage from browsers and instant messengers (APK, PDF, ZIP).
• 🗃️ Temporary files: Bluetooth, Notifications – can be cleaned completely.

The Android/obb folder is particularly noteworthy. It stores additional game data (e.g., graphics packages for PUBG Mobile or Call of Duty). If the game is already deleted, feel free to erase the corresponding folder in obb - it can weigh several gigabytes!

Which folders to delete is DARPASSIBLE (risk of “bricking”)

Now, the most important thing is which folders on the Redmi Note 8 Pro you can't touch unless you want to lose data or even lose a working phone, and even if they take up a lot of space, cleaning them can lead to:

• 🚨 Loss of functionality (e.g., camera or Wi-Fi will not work).
• 🔄 Located inclusion (bootloop).
• 📵 Complete inoperability (reflashing required).

List of prohibited folders for deletion:

• 🛑 MIUI (Other than theme and wallpaper subfolders – contains critical shell files.
• 🛑 Android/data/com.android.* — Android system applications.
• 🛑 Android/obb (If the game is still installed, the removal will lead to the collapse of the game.
• 🛑 Alarms, Ringtones, Notifications – without them, the phone will be dumb».
• 🛑 MIUI/DSP — sound and vibration settings.

It is especially dangerous to delete files in /data or /system folders, which are privileged partitions that are only accessible with root rights.

⚠️ Warning: If you see a folder called lost.dir, don't delete it! These are recovered files after a file system crash. Better move the contents to a safe place and clear the folder.

How to clean your memory correctly: step-by-step instructions

To avoid damaging the system, follow this algorithm:

1. Back up important data (photos, contacts, messages) through Settings → About Phone → Backup.
2. Use the built-in MIUI tools: Open Settings → Memory. Click "Clean" next to the "Junk" section. Select "Deep Clean" to remove the cache of system applications.
3. Manual cleanup via file manager: Install Mi File Manager or Solid Explorer. Go to /storage/emulated/0/. Remove folder contents from the "safe list" (see section above).

Clearing the cache of individual applications

• Go to Settings → Applications → Application Management.
• Select an app (like Facebook or TikTok).
• Click on “Clear Cache” and “Clear Data” (if you need to reset settings).

For advanced users, if you have root access, you can use SD Maid or Root Cleaner to clean your system debris deeply, but without root, these programs are useless.

💡

Before clearing the cache of games (such as Genshin Impact or Honor of Kings), check if the account is tied to the game's servers. Some games erase the progress in cleaning up the data!

Hidden folders and system debris: what can be removed

• 🗃️.Trash - basket MIUI. Here are the files you deleted for the last 30 days.
• 📁.estrongs – temporary manager files ES File Explorer (if you have used it).
• 🔍.thumbnails is another folder with thumbnails (besides the thumbnails) DCIM/.thumbnails).
• 📊.Data – sometimes it stores application log files (you can delete if the folder is not empty).

Be careful about folders with a dot at the beginning if they don't come up to you,.android_secure contains encrypted application data – its deletion will lead to errors.

Another source of hidden garbage – log files MIUI. They're stored in /sdcard/MIUI/debug_log And they can take hundreds of megabytes, and they're only used to diagnose errors, so you can delete them safely. MIUI/backup — Here are old backups that are no longer relevant.

💡

Hidden folders with a point at the beginning (.Trash,.thumbnails) often contain duplicate files that have long been deleted.

Cleaning after MIUI updates: what can be erased

After updating MIUI on Redmi Note 8 Pro, unnecessary files remain in memory:

• 📦 Older versions of the firmware in /sdcard/MIUI/ota (weight ~1.5–2 GB).
• 📝 Log files updates in /sdcard/MIUI/debug_log/update.
• 🗑️ Temporary files in /sdcard/MIUI/backup/AllBackup (if backup is not needed).

To clean them up:

1. Open Mi File Manager.
2. Go to /sdcard/MIUI/.
3. Delete the contents of the ota folders, debug_log Backup (if there are no actual backups).
4. Reboot the phone.

1. Turn off the Redmi Note 8 Pro.
2. Press Power + Volume up to enter Recovery.
3. Choose Wipe & Reset → Wipe Cache.
4. Confirm the action and restart.

⚠️ Warning: Do not confuse Wipe Cache and Wipe Data in recovery! The second option will erase all your data (photos, apps, settings) and return the phone to factory condition.

Alternative ways to free up memory

If even after cleaning folders there is not enough space, try these methods:

• 🔄 Transfer of applications to SD-Map: Insert microSD (up to 256GB). Go to Settings → Annexes → Application management. Select the application. → «Move it to SD-Limitation: Not all applications support portability.
• ☁️ Cloud storage: Upload photos to Google Photos or Mi Cloud. enable automatic sync in application settings. Delete local copies after downloading.
• 🗃️ Media compression: Use Files by Google to compress photos and videos. The app will offer to reduce the size of files without critical loss of quality.
• 🛠️ Disabling Pre-installed Applications: Go to Settings → Apps. Find unnecessary system applications (such as Mi Music or Mi Video). Click "Disable" (not "Delete»!).

More radical methods are available for root-access users:

• Remove system applications through Titanium Backup.
• Clear /data/dalvik-cache folder (Dalvik cache)
• Remove unnecessary localizations in /system/app.

But remember, doing the wrong thing with root can lead to loss of warranty and phone inoperability. If you are not sure, you should consult a specialist.
