Owners of Xiaomi smartphones often face a situation where the system automatically launches files in an inappropriate program, PDF-The document can open in a browser instead of a convenient reader, and the video can open in a system player that does not support the desired codecs. MIUI HyperOS, which aims to minimize the number of questions to users.
Changing the default application is not just a cosmetic procedure, but a necessity for comfortable work with multimedia and documents. Standard Android algorithms based on Xiaomi sometimes “remember” the first file launch and stop offering choices, blocking access to more functional software. Understanding the mechanisms of file management will allow you to fully control the device.
In this article, we will discuss all the available ways to force files to open through the tool you need, we will look at the standard methods through the file manager, deep system settings for resetting preferences and working with archives, which are often difficult for beginners.
The basic method through the menu "Open with help"
The simplest and most obvious method that many people ignore is to use the context menu of the Explorer. Xiaomi's File Manager built-in has enough functionality to redirect data streams. With a long click on the file, an action menu appears in the list where you can select the "Open with Help" option.
If the system has previously memorized your choice for this type of file, the button can immediately start the application, in which case you must first clear the default settings. However, if you have just installed a new program or this is the first file launch after the reset, the system will offer a list of compatible applications.
⚠️ Warning: Do not select the "Only Once" option if you want to permanently change the behavior of the system. Single startup does not reset previous file associations, and after a minute you will again face opening in the unnecessary program.
For files of specific formats, such as engineering logs or databases, the list may be empty, in which case the system does not know how to process the request. HEX-an editor or text viewer who registers himself in the system as a processor of any text streams.
💡
If there is no application in the Open with the help list, try running the program itself first, and then using the Open File function inside it to navigate to the desired document.
Resetting application settings by default
Often the problem lies not in the lack of choice, but in the “stuck” cache of preferences. Android stores information about which application the user chose for a certain application. MIME-To get the system to ask you about your preferences again, you need to reset those settings for a particular infringing application.
Go to Settings → Applications → All Apps. Find a program that is currently incorrectly opening your files (such as Chrome for PDF or Video Gallery). Inside the app menu, find the option “Open by default” or “Start by default”.
Press the Default Settings Clear button. After that action, the next time you run a file of this type, Xiaomi will again suggest you select the program, which is a universal solution for most software conflicts.
☑️ Algorithm of resetting preferences
There is also a global reset of all preferences, but it will affect the entire system at once.This can be useful if you have updated your firmware and the old file associations are not working properly.The path to this feature is: Settings → Applications → Three dots in the corner → Reset application settings.
Working with ZIP and RAR archives on Xiaomi
Archives are a separate category of files that Xiaomi users often have trouble with. A standard Explorer may try to open the archive as a folder or offer to download a plugin instead of using the ZArchiver or RAR you installed. The problem often lies in the permissions to access the storage.
Make sure that the third-party archiver has all the necessary rights. In modern versions of Android, access to the file system is strictly regulated. Go to the settings of the archive application, select Permissions, and make sure that access to Photos and Media or Files is set to Allow Management of All Files.
| Type of archive | Recommended annex | The default problem |
|---|---|---|
| .ZIP | Google Files / ZArchiver | Opens as a folder without unpacking |
| .RAR | RAR for Android | The system doesn't see the archiver. |
| .7Z | 7Zipper | Requires the installation of plugins |
| .TAR.GZ | ZArchiver | Opens in a text editor |
If automatic opening doesn't work, use the folder unpack method. Instead of trying to open a file with a double tap, select the option "Extract" or "Unpack here." This will create a regular folder with content that can be opened any convenient way.
Why is Xiaomi blocking some archives?
Setting up associations for multimedia files
Video and audio files are the most common cause of conflict. VLC or MX Player, but the system persists in running videos in a standard "Mi Video," which may not support subtitles or certain audio codecs. MIME-Types that the application registers when installing.
Sometimes it helps to reinstall your preferred player: Remove the app, restart the smartphone and install it again from Google Play. When you first run the video file, the system will find a new app and ask about priority. Make sure the Always tick is active.
For audio files, the situation is similar: If tracks are opened in a browser or system recorder, check if these programs have the right to open audio by default, and clearing these rights will return the choice to you.
⚠️ Note: Some Xiaomi system applications cannot be removed or completely disabled without root rights.If Mi Video continues to intercept files, use third-party launchers or file managers with built-in player selection, ignoring the system.
Use of Third-Party File Managers
Xiaomi’s regular Explorer is functional, but sometimes too simplistic for advanced users. Installing an alternative file manager like Solid Explorer, FX File Explorer, or Files by Google solves 90% of file opening problems. These applications have their own MIME-type processing mechanisms.
Third-party managers allow you to manually assign an action for each file type, and you can find the File Types or Associations section in the File Types settings of the Explorer, where you can write, "All.pdf files open through Adobe Acrobat," ignoring the Android system settings.
They also often have an inbuilt Open to.. function that compulsorily calls the system selection menu even if the association is already established, which is achieved by emulating a new Intent request from the system.
💡
A third-party file manager is a “control panel” for your file system, allowing you to bypass the limitations of a standard MIUI shell.
Solving problems with office documents
Word, Excel, and PowerPoint documents require a special approach, as formatting can be “swimmed” across applications. Often users want to open a document in WPS Office, and it opens in Google Docs or the online version through a browser, which is due to the fact that online services often have a higher priority in the system.
To solve the problem, you need to disable the ability of browsers and online offices to open files locally. Go to the settings of Chrome or Google Docs, find the section “Open links” or “Open supported files” and select “Do not open in this application”.
Then, when you try to open a document, the system will look for a local application, and if there are more than one, it will ask you again, select your main office suite and record the selection.
It's important to keep an eye on office suites. After a major update, the app may lose its association rights, and the selection process will have to be repeated. This is normal Android security behavior.
