Xiaomi, Redmi and Poco smartphone owners often face the need to free up internal storage, which is quickly filled with media and apps. One common reason for space shortages is forgotten APK installation packages that remain in memory even after successful software installation, which can take from a few megabytes to tens of gigabytes if you regularly update software manually or download heavy games from third-party sources.
The cleaning process is not always obvious, as the standard MIUI or HyperOS shell interface hides some system folders from the average user. Incorrect removal of system components can lead to unstable device operation, so it is important to clearly understand which files are to be eliminated and which ones are not to be touched. In this article, we will discuss all the safe ways to get rid of excess debris.
We’ll look at the full-time file manager tools, storage settings, and more advanced methods for cleaning cache and residual files.You’ll learn to distinguish between installation packages and application data, which will help you keep your Android smartphone clean without risking damage to the operating system.
Use of the built-in file manager
The easiest and safest way to find and remove APK-Files – Use the Explorer (or Files) app preinstalled, and this tool already has built-in categorization that allows you to quickly sort installation packages from other documents. You don’t have to search for them manually in the depths of system directories, which greatly reduces the risk of error.
Open Explorer on the home screen or in the Tools folder. On the home screen, you'll see icon sections like Images, Videos, Documents. Find an icon that says APK or Installation Packages. When you click on it, the system will display a list of all the files found with the.apk extension that are in user-accessible folders like Download or MIUI/Downloads.
To delete, select the files you want with a long press, and then you'll see an action bar at the bottom of the screen, and then you'll click on the basket icon or the Delete button, and the system can request confirmation of the operation, because this action is irreversible without a backup.
⚠️ Note: Before removing, make sure that the application that matches this APK-The file is already installed and is working correctly. If you delete the installer before the installation is complete, you will have to download the file again.
If a standard explorer doesn't display some files, they may be hidden or in a protected area, so you can use the in-app search function, type in the.apk extension and the manager will show all the entries of this type of files in the device's internal memory.
☑️ Pre-deletion check
Cleaning through storage settings
The MIUI and HyperOS shells have a powerful built-in analyzer that allows you to manage occupied space without third-party utilities, and the good thing about this method is that it shows not only the files, but also the volume occupied by each application, allowing you to remove not only the installer, but also the cache.
Go to the Settings menu of your smartphone. Find the About Phone section or select Advanced Settings (depending on the OS version, the path may differ, most often it is Settings → Memory). Here you will see a visualization of occupied space. Click on the Cleanup button or select the category of applications.
In the application management section, you can find a specific program you want to check. Click on it to see the details of memory usage. You can often find the Clear Data or Clear Cache button here. However, to delete the APK installation file, you need to go back to the file list or use the built-in Cleanup tool.
The Security app (green zipper icon), which is a system for Xiaomi, has a Cleanup section.The system will scan the device for junk files, including old ones. APK-Installators. It's an automated process that's safe for beginners.
💡
Run the built-in cleanup in the Security app regularly to delete temporary files and installer residues automatically without waiting for memory to overflow.
It is worth noting that automatic cleaning may not delete files if they are marked as "important" or are in excluded folders. Therefore, manual control through the file manager is sometimes necessary for complete cleanup.
Removal via computer and debugging mode
For advanced users who need to remove system or hidden APK-files that are not visible through the phone interface will be suitable for a PC connection. This method requires the activation of the developer mode and the use of the protocol. ADB (Android Debug Bridge).
First, activate Developer Mode. Go to Settings → About Phone and click 7-10 times in a row on MIUI Version (or OS Version) until the notification “You’ve become a developer” appears. Then go to Additional → For Developers and turn on the USB Debugging Toggle.
Connect your smartphone to your computer through USB-You'll see a request for debugging permission on your phone screen -- click "Allow." You'll need to install a minimum set of drivers on your computer. ADB. After connecting in the PC command line, enter a command to access the file system:
adb shell pm list packages -3This command will show a list of third-party packages. To remove a particular application (if removing the APK means removing the application itself), the command is used:
adb uninstall com.example.packageHowever, if your goal is to physically remove the installer file from the system folders, it is easier to use file transfer mode (MTP). Connect the phone as File Transfer, open it in My Computer and manually navigate to the Internal Storage/Download or MIUI/Downloads folder, where APK is most often stored.
⚠️ Attention: Use of teams ADB To remove system packets, you can "brick" your device. Only remove those packets that you are absolutely sure of.
Working with third-party file managers
Standard tools aren’t always convenient, especially if you need to find duplicates or hidden files. Third-party file managers like Files by Google, Solid Explorer or Total Commander provide deeper access to the Android file system.
Once you install an application like Solid Explorer, you need to give it all the necessary permissions to access the storage. Unlike a standard explorer, these applications can display folder structure more clearly and have built-in tools to search by file type. Type in *.apk to see all the installation packages on the device.
Third-party managers have the advantage of being able to batch processing and having a Recycle Bin, and if you accidentally delete an important file, it can be recovered from the application basket within a certain time, and many of them are also able to analyze the size of folders and show which directories occupy the most space.
Some managers allow you to connect to cloud storage, which is convenient for moving around. APK-files to an external server before deleting them if you plan to use them in the future on another device.
Why can't some APKs be removed?
Analysis of APK file types and risks
Not all APK files are the same. Understanding the difference between system, user and malicious files is critical to your Xiaomi security. Deleting the wrong file could disrupt Google services or the MIUI shell itself.
Below is a table that will help classify the files found:
| Type APK | Location. | Can I remove it? | Risks. |
|---|---|---|---|
| Customized | /storage/emulated/0/Download | Yes, after installation. | Not if the app is working. |
| System (Stock) | /system/app or /system/priv-app | No (no Root) | High, possible loss of functionality |
| Updating the system | /data/dalvik-cache | No. | Critical, download failure |
| Malicious. | Any folder. | Yeah, right now. | Data breach, advertising |
Particular attention should be paid to files in the folder Android/obb or Android/data. Thought it wasn't. APK-Installators, they store cached game and application data, and deleting them will free up space, but the application will have to be re-downloaded or re-authorized.
If you find out APK-A file with a suspicious name or in a strange folder that you haven't downloaded may be a sign of malware, in which case deleting the file may not be enough - a full antivirus check is required.
💡
It is safest to remove only those. APK-files that you downloaded yourself to the Download folder and successfully installed.
What to do if the file is not deleted
Sometimes users are faced with a situation where the system says "File is busy" or "No permissions", which often happens if the installation process is not completed, or the file is used by the background service, in which case simply pressing the delete button will not help.
The first step is to restart the device, which will complete all the freezes and release the file locks. After the reboot, try to delete the file again through the file manager. If persists is a problem, check if the installation process is running in the background.
Another cause is file system damage: If the disk has errors, writing and deleting can be blocked, in which case cleaning the recovery partition cache (without loss of data) or checking the disk through the computer using the chkdsk utility (for Windows) can help, although this requires certain skills.
Also worth checking is access rights. In newer versions of Android (11, 12, 13, 14), access to the Android/data folder is limited. A standard Explorer may not have permission to delete files inside this directory. It will require special access, which can be accessed through the “Use this folder” menu in the folder selection system dialog, or a third-party file manager with SAF (Storage Access Framework) support.
⚠️ Warning: Do not force files to be deleted through console system commands unless you understand their purpose.This can lead to a cyclical smartphone reboot.
