Owners of Xiaomi, Redmi and Poco smartphones often face the mysterious disappearance of free space in the deviceβs memory. The internal drive suddenly becomes crowded, even though the user has not installed new applications or taken hundreds of photos, the culprit of this situation is often the system folder that accumulates firmware distributions to automatically update MIUI or HyperOS.
These files can take anywhere from a few gigabytes to tens of gigabytes, significantly slowing down the gadget. downloaded_rom It is safe for the current version of the system, unless you plan to roll back to the older firmware right now.Understanding the structure of the Android file system allows you to effectively manage the space without using third-party software.
In this article, we will look at where to find these heavyweight archives and how to get rid of them, and we will look at both standard methods through file managers and more advanced ways to clean through the computer, which will help you return precious gigabytes for personal use.
Why the system keeps the old firmware versions
The MIUI shell is designed to be user-friendly, and the automatic update mechanism is set to load installation packets in the background by default, so that when the new version is installed, there is no need for an active Internet connection, which speeds up the process and reduces the risk of errors when the signal is unstable.
However, developers donβt always automatically clean up this data after successful installation, and as a result, there may be multiple versions of updates on the disk, from the current to the previous one, which you may not even have manually installed. The system partition does not have a strict limit on storing this cached data, so they occupy space in the user partition.
In addition, files can remain after an interrupted download or failed installation attempt. If the update has been downloaded, but the installation was canceled or interrupted by a restart, the distribution remains dead weight.
β οΈ Note: Before deleting any system files, make sure the phone is fully charged. Although deleting installers does not affect the operating system, accidentally deleting other files in the root directory can cause crashes.
Search and Remove Through Built-in Conductor
The easiest way to free up space is to use the standard Explorer tool, which is preinstalled on all Xiaomi devices. You do not need to download additional apps from Google Play. The algorithm is simple enough, but requires careful navigation through directories.
Open the app first and go to file viewing mode, not categories. You need to get to the root of the internal drive. downloaded_rom. This is where all the service packs you download are stored, and inside you'll see files with the.zip extension, the names of which usually contain the firmware version number.
Select all the archives you find and press the delete button. The system may request permission confirmation, as you are working with system directories. Allow access, and the files will be moved to the recycle bin or permanently deleted, depending on your Explorer settings.
βοΈ Pre-deletion check
It is important to note that after cleaning this folder, the automatic update may download the package again if you do not turn off this feature in the settings.
Use of the Cleaning Application (Cleaner)
The MIUI shell has a built-in Security app that includes the Cleanup tool. This module is able to find remnants of updates that a user may have missed in a manual search. The scan algorithms analyze file size and type, suggesting that you delete what you don't need to run the phone.
Run the Security app and select Cleanup. After the initial scan, the system will prompt you to remove the garbage. However, the standard mode may not see large firmware files. Click on the Deep Cleanup icon or select the Big Files category. This often hides 2-4 GB distributions.
In the list of found objects, look for files with names that contain miui_ or global_. Be careful: don't delete personal videos or archives of documents if you've put them in there.Sort files by size to find heavy update packages faster.
| File type | Location. | Can I remove it? | Size (approximately) |
|---|---|---|---|
| OTA package | /downloaded_rom/ | Yes. | 2-5 GB |
| Cash updates. | /data/dalvik-cache/ | No (systemic) | 1-3 GB |
| Logs of installation | /data/log/ | Yes (via engineering menu) | 100-500 MB |
| Backup copy | /MIUI/backup/ | Unless you need to. | 10-50 GB |

Use the βStorage Analyzerβ feature in the Security app to visually see which folders take up the most space on your device.
Cleaning through connection to a computer
If the built-in methods can not delete files or they appear again, it is worth using a computer. USB connection gives greater access to the file system and allows you to use powerful analysis tools such as Total Commander or standard Windows Explorer.
Connect your smartphone with a cable to your PC. On your phone screen, select the mode of operation (MTP). On your computer, open the disk that appears. Find the root folder and find the directory. downloaded_rom. Computer interface allows you to quickly allocate and delete large amounts of data.
The advantage of this method is that you can pre-copy suspicious files onto your computer's hard drive by backing up, so you can make sure that nothing important is lost.
β οΈ Warning: When connecting to your computer, do not delete files with unknown names from system folders that are not on the recommended cleanup list.
Disabling Automatic Update Downloading
To keep the memory overflow problem from returning, you need to change your boot settings. The default system tends to keep the phone up to date, but you can limit this process, and this is especially true for devices with a small amount of internal memory.
Go to Settings, then select About Phone. Click on MIUI or HyperOS to open the Update menu. In the upper right corner, click on three dots and select Settings. You need to turn off Auto Update and, if any, Download Updates in the background.
After that, the phone will stop downloading heavy packets on its own, and the update will only happen when you go to the menu and press the check button, which gives you complete control over when and what files appear in your deviceβs memory.
Hidden Loader Settings
What to do if the files are returned
Sometimes users are faced with a situation where the folder downloaded_rom It's cleaned, but it's bloated again after a couple of days, which could indicate that the system's update service is out of order, or that the phone is trying to update in a loop, but it can't finish the process.
First of all, try to clear the data from the Component Update application itself. Go to Settings β Apps β All Apps, find the Component Update (or Updater) list. Click Clean and select Clean All. This will reset the bootloader cache and stop the reboot.
If that doesn't work, check if the Extended Memory function is enabled. In some cases, the system may use a portion of the user's memory for virtual RAM, and update files may conflict with this process.
- π Check for system errors in the About Phone menu.
- ποΈ Delete all files from the folder downloaded_rom repeatedly.
- π΅ Turn off Wi-Fi and try to clear the update service data.
- π Make sure that the phone does not have third-party launchers that block the system.

Cyclical file downloads often indicate a conflict of system components versions, which is solved by a complete reset of the Component Update application.
