Xiaomi Redmi 7 is a popular smartphone with 32 or 64 GB of memory, but even this amount is not enough over time. The main βeaterβ of space is the mysterious βOtherβ folder in the Storage section. It can take from 5 to 20+ GB, but what it is and how to clean it is not clear to everyone. In this article, we will analyze why the folder grows, what files are stored in it, and 5 proven ways to clean it without risk to the system.
Let me warn you right away: on Redmi 7 with MIUI 10-12, the Other folder often contains update cache, system logs, and remnants of remote applications that are not cleaned by standard means. If you've tried to click Clear in the storage settings, but the volume hasn't decreased, you're here. We've tested all the methods on real devices and only selected the ones that give results.
What is the βOtherβ folder on Xiaomi and why it takes up so much space
The Other folder (or Other in the English version of MIUI) is the garbage box of the operating system.
- π Update cache MIUI β temporary firmware files that are downloaded but not deleted after installation.
- ποΈ System and application logs β report errors, memory dumps and service operation (.log,.dump).
- π§Ή Remnants of Remote Applications β Lib, Cache and Settings that Remain After Uninstallation.
- π Kesh. Dalvik/ART β Optimized files to speed up application launches (can weigh up to a maximum of two) 1β2 GB).
- π± Files. MIUI-Themes and widgets β downloaded designs that are not used.
On Redmi 7, the problem is compounded by the fact that the system defaults to debugging logs (for Xiaomi diagnostics) and does not clear the update cache automatically. For example, after updating MIUI from 10 to 12, up to 3 to 5 GB of unnecessary files may remain in the Other folder.
- π΅ Musical metadata - album covers, cache players.
- πΈ Gallery miniatures - preview photos and videos (.thumbnail).
- π‘ bootloader cache β files downloaded through a browser or messengers, but not saved by the user.
In our testing, Redmi 7 with MIUI 11 has an average 8 to 12 GB folder that takes up active use over the year, and if you haven't cleaned it before, it can go up to 15 to 20 GB.
Method 1: Cleaning through built-in MIUI tools (no root)
Let's start with the safest method, which is to use standard MIUI features, which doesn't require super-user rights and is suitable even for beginners.
- Open the Settings β Storage.
- Slip on the line "Other" (or "Other").
- The system will scan files and show categories: βCashβ, βDownloadsβ, βLogsβ, etc. Select βCashβ and click βCleanβ.
- Go back and select Logs and Dumps β Clean.
This way will remove:
- ποΈ Application and system cache (up to 1β3 GB).
- π Error Logs and Dumps (up to 500 MB).
- π Temporary update files (if not protected by the system).
However, not all files in the Other folder will be available for deletion, such as the Dalvik cache and some MIUI system logs are blocked, so move on to the next method.

If the volume of the Other folder has not changed after cleaning, restart your smartphone β sometimes MIUI does not update the storage data immediately.
Method 2: Delete Dalvik/ART cache via Recovery (without data loss)
Dalvik/ART cache is optimized files to speed up applications. On Redmi 7, it can take 1-2 GB, but it can not be cleaned by standard means.
- Turn off your smartphone.
- Press the Power button + Volume up until the MI logo appears.
- From the Recovery menu, select Wipe & Reset β Wipe Cache (use volume buttons for navigation, power for selection).
- Confirm the action and wait for the completion (it will take 1-2 minutes).
- Reboot the device (Reboot β System)
This method does not delete user data, but resets the cache of all applications. After a reboot, the system can run a little slower for the first 5-10 minutes - this is normal (the cache is rebuilt).

If the volume of the Other folder has decreased slightly after cleaning the cache, then the main debris is in the other files.
Method 3: Manually delete unnecessary files through file manager
Some files in the Other folder can be manually deleted if you know where they are stored, and any file manager with access to system folders (such as Mi File Manager or Solid Explorer) will do.
Open the file manager and go to the following folders (use Show Hidden Files in the Manager Settings):
| folder | What can be removed | Approximate volume |
|---|---|---|
| /data/log/ | System and application logs (.log,.txt) | 100-500 MB |
| /cache/ | Temporary update files and recovery cache | 500 MB-2 GB |
| /data/dalvik-cache/ | Dalvik's cache (unless cleared through Recovery) | 1-2 GB |
| /data/local/tmp/ | Temporary files of the application installer | up to 100MB |
| /sdcard/Android/data/ | Cache and remote application data | 1-5 GB |
Attention, don't delete files from folders.
- π« /system/ β System files (you can damage the firmware).
- π« /data/app/ β fixed-appendice.
- π« /data/data/ β Application settings (risk of data loss).
If you're not sure if a file can be deleted, skip it, for example, the /cache/ folder may contain important update files that the system uses when it updates next.

Method 4: Using ADB for deep cleaning (for advanced)
If previous methods failed, you can connect to your smartphone via ADB (Android Debug Bridge) and manually delete unnecessary files, a method that requires a computer and minimal command line knowledge.
What you need:
- π» Computer with Windows/Linux/macOS.
- π USB-cable (preferably original).
- π₯ ADB Fastboot Tools (download and unpack).
- π§ Included debugging by USB on a smartphone (Settings) β The phone. β Version. MIUI (tap 7 times) β Additionally. β For developers β Debugging by USB).
Instructions:
- Connect Redmi 7 to your computer and allow debugging (a request will appear on the smartphone screen).
- Open the command prompt (Windows) or terminal (Linux/macOS) in the adb folder.
- Enter the command to check the connection: Adb devices must appear serial number of your device.
- Delete Dalvik cache (if not cleared through Recovery): adb shell pm clear --user 0 com.android.defcontainer
- Clear the folder with the logs: adb shell rm -rf /data/log/*
- Delete the temporary update files: adb shell rm -rf /cache/*
After completing the commands, restart the smartphone:
adb shell rebootAttention! rm -rf commands permanently delete files, and if you make a mistake (e.g., type rm -rf /data/ instead of /data/log/), you will reset your settings completely.
π‘
ADB allows you to delete files that are not available through standard MIUI tools, but requires accuracy. If you are not sure about commands, use more secure methods.
Method 5: Reset to factory settings (extreme case)
If the Other folder takes up more than 10GB and previous methods didnβt work, the last option is a full reset, which will delete all data on the device, including apps, photos and settings, but return the storage to its original state.
How to reset:
- Save important data to your computer or to the cloud (Mi Cloud, Google Drive).
- Open Settings β Additional β Recovery and Reset β Resetting.
- Select βErase all dataβ and confirm.
- Wait for the completion (it will take 5-10 minutes) and set the smartphone as new.
Once reset, the Other folder will take up to 1-2 GB (a normal volume for a clean system).
- β οΈ All applications and data will be deleted.
- β οΈ Reference to the Mi-account will remain (requires the entry of a password after resetting).
- β οΈ Updates MIUI Will remain (unless you choose Reset to Factory Firmware in Recovery).
If you donβt want to lose data, try first transferring files to a memory card or cloud, and then perform a reset.
How to prevent the growth of the βOtherβ folder in the future
To prevent the βOtherβ folder from taking up gigabytes again, follow these tips:
- π Clean the cache regularly in Settings β Warehouse β Other (once 1-2 months).
- π₯ Turn off automatic updates MIUI, If you do not want firmware files to be downloaded in the background (Settings) β The phone. β Updating the system β βοΈ β Auto-update).
- ποΈ Use third-party cleaners (for example, SD Maid or Files by Google to remove residues from apps.
- π Transfer heavy applications to a memory card (if supported).
- π§ Turn off log collection (for power users): adb shell setprop persist.logd.size 0
You should also monitor the storage with applications like DiskUsage or Storage Analyzer, which show which files are in the Other folder.

If you install and remove apps frequently, use Lite versions (e.g. Facebook Lite, Messenger Lite) β they take up less space and leave less trash.
