Why Redmi 9 is getting trash in the Downloads folder and how to fix it
Download folder (or “downloads”) on Xiaomi Redmi 9 smartphones is one of the most clogged storages of unnecessary files, APK-Application files, temporary archives, even duplicate media that you've long forgotten, and the problem is compounded by the fact that the system is a real mess. MIUI The default does not clean this folder automatically, and many users simply do not know where it is.
According to the Clean Master study (2023), device-wise 64 GB of memory on average 12–15% It's the downloads that take up the spaces, and that doesn't include the app cache! 9 modestly 32/64 GB of internal memory each megabyte counts, but simply deleting files is not enough: you need to understand which ones are safe to erase and which can disrupt applications (for example, updates for games or offline maps). In this article, we will analyze all methods - from basic to advanced, including cleaning through the ADB and hidden system folders.
Before you start, check how much space the downloads on your device take up:
- Open the settings → About the phone → Memory.
- Click on the "Files" or "Other Files" section.
- Find the Download line – this shows the folder volume.
If the figure is more than 1-2 GB, it is time to act.
Method 1: Delete via standard MIUI file manager
The easiest method is to use Xiaomi’s built-in Explorer (or Files) preinstalled on all Redmi devices and does not require additional permissions.
- Open the Files app (an icon with a blue folder).
- In the lower menu, select the Category → Downloads tab.
- Slip the Control button (or pinch your finger on any file).
- Check the unneeded files. To select all, click on the ✓ icon in the upper right corner.
- Click Remove (basket) and confirm the action.
⚠️ Note: This folder may store important files, for example:
- 📄 Documents for work (PDF, DOCX) mail-mail.
- 🎮 Game saving (if the game uses local files).
- 📱 APK-Application files that you have manually installed.
Before mass deletion, sort files by date (click on the icon) ⋮ → Sorting) and check the latest downloads.
Have not removed documents for work|Not really. APK-file|Screenshots and memes are checked for importance|Is the cart cleaned (it also takes up space)-->
If there are too many files, search for extensions:
- 🔍 Enter.apk in the search bar – will show all the installers of applications.
- 🔍 Search.zip or.rar will display archives.
- 🔍 Filter.mp4 or.mp3 Helps you find media files.
Method 2: Cleaning with Google Files (recommended for deep cleaning)
Google Files is more efficient than standard MIUI Explorer, which analyzes garbage, duplicates and large files, download it from the Play Market if you don’t already have it installed.
Cleaning instructions:
- Open Google Files and go to the Cleanup tab.
- Wait for the analysis to be completed (it may take 1-2 minutes).
- In the section Large files or downloads, select the unnecessary.
- Press Clean or Delete.
The advantages of Google Files over standard Explorer:
- 🧹 Automatically finds duplicates (e.g., identical memes or screenshots).
- 📊 Shows which files take up the most space.
- 🔄 Offers to clear the application cache in one click.
💡
Google Files has a “Secure Folder” feature – transfer important files there before mass deletion so you don’t accidentally lose them.
⚠️ Note: If files are still displayed in memory after cleaning through Google Files, check the folder Android/data. Some apps (like Telegram) save downloads there rather than Download.
Method 3: Remove via ADB (for power users)
If standard methods don’t help (e.g. files aren’t deleted because of a File is busy error), you can use Android Debug Bridge (ADB), which requires you to connect your phone to your computer, but allows you to delete even protected files.
Step-by-step:
- Download ADB Tools on PC and unpack the archive.
- On your phone, activate Developer Mode: Go to Settings → About Phone. Tap 7 times on the MIUI Version line. Go back to Settings → Additional → Developer. Turn on USB Debugging.

Method 4: Cleaning with MIUI Cleaner (built-in utility)

⚠️ Note: Delete files from application folders (for example, /Android/data/com.tencent.mm/MicroMsg/Download For WeChat, it can cause crashes. Don't touch files with extensions:
- .db is databases.
- .xml is a configuration file.
- .so are system libraries.
