"Other files"
Many people mistakenly think that Others is just cache or junk. In fact, this includes update remnants, MIUI log files, application temporary data, and hidden folders from Xiaomi services (such as Mi Cloud or Mi Video). Incorrect cleaning can lead to failures, from camera errors to complete loss of communication. So we collected only proven methods, sorted by risk level, from safe to advanced.
In this article you will find:
- 🔍 Analysis of the structure of the folder “Other files” on Redmi 4X — what exactly is.
- 🧹 Built-in tools MIUI root-free.
- 🛠️ Manual cleaning through the file manager and ADB (skilled).
- ⚠️ List of dangerous folders that can not be deleted under any circumstances.
1.What are the “Other Files” on Xiaomi Redmi 4X and why do they take up so much space
Category “Others” in the storage menu MIUI — It's a garbage bin for data that the system can't categorize as standard (photos, videos, apps). 4X They usually come in:
- 📁 Cash updates (OTA): Firmware files that have been downloaded but have not been installed can weigh up to 1-2 GB.
- 📄 Log files (.log,.txt): System and application error logs that accumulate over the years.
- 🎬 Media remnants: video miniatures, music covers, temporary gallery files.
- 🔄 Synchronization data: duplicate contacts, notes and backups from Mi Account.
On Redmi 4X with MIUI 8-11 (the most common versions on this device), the problem is compounded by the fact that the system does not clear the cache automatically after updates. For example, after installing the firmware through Updater, the /cache folder can remain clogged with files for 500-800 MB. In addition, applications like Mi Video or Mi Music create hidden folders with downloads that are not visible in the standard file manager.
To understand the scale of the problem, check the memory distribution:
- Open Settings → Memory of the device.
- Click on the chart and select “Other Files”.
- The system will show the details – usually here you can see that 30-50% is occupied by “System Data”.
2.Safe cleaning through built-in MIUI tools
Before you go into system folders, try standard methods. They don't require root rights and are suitable even for beginners.
Clearing the application cache
- 📱 Go to Settings. → Annexes → Application management.
- 🔍 Sort by size (click on three dots in the upper right corner).
- 🧹 Select apps with large cache (e.g. YouTube, Facebook, Mi Video) and click Clear Cache».
Important: Do not clear your data from system applications (such as Settings or Phone) – this can reset your settings!
2.2.Use of “Memory Cleansing”
MIUI has a built-in garbage disposal tool:
- Open the Security app (shield icon).
- Select “Cleaning” → “Deep Cleaning”.
- Check the boxes opposite “Residual Files”, “Update Cache” and “Log Files”.
- Press "Clear."
This method removes up to 1-1.5 GB of unnecessary data, but does not touch hidden folders from Xiaomi services.
Removal of downloads and duplicates
Download folder and duplicate photos/video often take up hundreds of megabytes:
- 📁 Open the Files (Standard Manager) MIUI).
- 🔍 Go to Categories → Download and delete unnecessary files.
- 🖼️ In the Images section, select Duplicates (if the feature is available).

3. Manual cleaning through file manager (no root)
If the built-in tools don't work, you'll have to dig deeper, and any file manager with access to system folders, like FX File Explorer or Solid Explorer, will do.
Note: Delete only the folders listed below: Mistake of system files can result in loss of communication, camera errors, or even a device blink (completely inoperable).
3.1. folders that can be deleted
| The way to the folder | What's stored | Max. Safe size for removal |
|---|---|---|
| /sdcard/Android/data/com.xiaomi.market/files | Cash Mi App Store (APK-update-file) | Up to 1GB |
| /sdcard/MIUI/backup/AllBackup | Old backups of the system | Up to 2GB |
| /sdcard/.thumbnails | Image and video miniatures | Up to 500MB |
| /sdcard/Download/rom | Remains of firmware after updates | Up to 1.5GB |

After cleaning, restart the device. If you notice lags or errors (for example, the theme of the registration is missing), restore the deleted files from the manager's basket.
💡
Before you delete the folders, take a screenshot of the contents, and if something goes wrong after cleaning, you can restore the structure.
4. Advanced cleaning through ADB (for power users)
If Other Files take up more than 3GB and standard methods don’t help, try cleaning through ADB (Android Debug Bridge), which requires a connection to a computer but allows you to remove system debris without root rights.
Preparation
- Download ADB Tools for Windows/macOS/Linux.
- Turn it on on Redmi. 4X «Debugging by USB» (Settings → The phone. → Version. MIUI — Press 7 times, then return to Settings → Additionally. → For developers).
- Connect the phone to the PC and confirm the debugging permission.
Cleaning commands
Open the command prompt (or Terminal) in the ADB folder and type:
adb shell
pm clear com.miui.cleanmaster # Clearing the Security cache
rm -rf /data/local/tmp/* # Delete temporary update files
rm -rf /cache/* # Clearing the system cache (requires a reboot)Warning: The command rm -rf /cache/* removes the cache of the kernel. Once it is executed, be sure to restart the device, otherwise you may freeze.
Clearing log files
Logs take hundreds of megabytes, but they can be safely deleted:
adb shell
su
rm -rf /data/log/*
rm -rf /data/anr/*
rm -rf /data/tombstones/*If the su command is not working, then the device has no root rights, in which case use only the first two lines (without su).
What if the ADB can’t see the device?
5.Reset to factory settings: Last chance

- Select “Erase all data”.
- Confirm the action and wait for the reboot (it will take 5-10 minutes).
5.2 What to do after discharge
- 🔄 Don’t restore data from a backup right away – first check how much “Other Files” take up on a clean system.
- 📥 Install applications gradually, keeping track of occupied space.
- 🚫 Avoid automatic syncing with Mi Cloud in the early days.
⚠️ Attention: On Redmi 4X Mi Account activation error may occur after reset. If the phone asks for an old account and you don't remember it, use access restoration or contact Xiaomi support.
💡
