You downloaded an important document, video, or archive to your Xiaomi, but when you try to open a file, the system gives an annoying notification: “There are no applications that support this format.” The situation is familiar to many people – especially if you are talking about rare extensions like.heic,.flac,.rar5 or enterprise formats like.dwg. Unlike computers where you can always install specialized software, on smartphones, the choice of programs is limited, and some formats are simply not recognized out of the box.
The problem is compounded by the fact that MIUI (Xiaomi firmware) does not always offer adequate solutions: instead of finding the right software, the system can simply ignore the file or suggest removing it. But don’t rush to get rid of the data! 90% of the time, you can open the file — you just need to know what tools to use. In this article, we will analyze 7 proven methods, including installing alternative applications, converting formats and even manually editing extensions. And for owners of older models (Redmi 4X, Mi A1) we will add individual life hacks — they often face problems due to outdated software.
1. Check the actual file extension
Often the problem is not the absence of apps, but the incorrect display of the extension. For example, a file called document.pdf.exe may disguise itself as PDF, but in fact be malicious EXE (which Android blocks by default) to verify the authenticity of the format:
- Install any file manager with detailed browsing support (e.g. Solid Explorer or FX File Manager).
- Find the problem file, click on it and hold it for 2 seconds → select Properties or Information.
- Check the file type or extension box, if it says.apk,.exe, or.bat, but you're expecting a document, the file is corrupted or infected.
⚠️ Note: If the extension doesn't match what you'd expect (e.g. photo.jpg is actually photo.jpg.crdownload), it's a sign of a file that's under-pitched. Try downloading it again or checking the source.
2. Install a universal application for opening files
The easiest solution is to download a multi-format application that supports rare extensions.-5 Verified options for Xiaomi:
- 📄 WPS Office – Opens.docx,.xlsx,.pptx, and.pdf and.txt. Supports editing and cloud storage.
- 🎵 VLC for Android – a universal player for.mkv,.flac,.avi and even.iso (as a media file).
- 🖼️ QuickPic – shows images in.heic,.webp,.tiff formats (embedded gallery Xiaomi often ignores them).
- 🗄️ RAR — filer,.7z,.zipx and other compressed formats.
- 📊 Google Files – scans your device for unnecessary files and suggests you open them through cloud services.
🔹 How to install: Go to the Play Store, type the name of the application in the search and click "Install." After installation, try to open the file again - the system should suggest a new application in the list.
💡
If the application does not appear in the Open with Help list, clear the Settings cache → Apps → All Apps → [File Manager Name] → Memory → Clear the cache.
3. Convert the file to a supported format
If you can't install an application (for example, due to memory limitations or regional locks), conversion is a reliable way to solve the problem.
- Upload the file to the cloud storage (Google Drive, Yandex Drive).
- Use online converters: 📄 CloudConvert – supports 200+ formats (including.heic) →.jpg). 🎵 Online Audio Converter – for.flac,.ape,.wav. 🗄️ Recommended format for conversion Quality losses.heic.jpg or.png Minimum (if High Quality is used).flac.mp3 (320 kbps) Noticeable for audiophiles.mkv.mp4 No (with the right settings).rar5.zip No
