Windows 10: How to set a Windows Store App as the default application for a file extension?

How do I set a Microsoft Windows Store App as the default application for files with a particular file extension? (On Microsoft Windows 10.)


Specifically, I want to set the Windows Store version of the KDE Advanced Text Editor (KATE) as the default application for MW (MediaWiki) sourcecode/plaintext files (e.g. "Main Page.mw"). I had this set up using the NT Windows desktop version of KATE, but I can't get it working with the RT Windows Store version of KATE.


https://www.microsoft.com/p/kate/9nwmw7bb59hw/


https://www.kate-editor.org/


Going to (Windows Settings --> Apps --> Default Apps --> "choose default apps by file type" --> "MW file") only allows me to choose between Microsoft Notepad and "look for an app in the Microsoft Store." Going to the Microsoft Windows Store though doesn't allow me to set KATE as the default application for MW files.


Trying to open an MW file with KATE doesn't work either. KATE integrates into the Microsoft Windows File Explorer by adding an option of "edit with KATE" to the right-click menu for files. This used to work with the NT Windows desktop version but doesn't appear to work with the RT Windows Store version. Selecting ("open with..." --> "choose another app") offers ("C:\Program Files\Kate\bin\kate.exe" "%1") but doesn't work since that is the location of the uninstalled NT desktop version of KATE.


The RT version is instead under "C:\Program Files\WindowsApps\" but I can't access this directory as Windows Administrator. Going to "more apps" --> "look for another app on this PC" doesn't give me access to add KATE (or any other Windows Store Apps) as the default application.


If there's no easy solution for this, then I can uninstall the RT version and reinstall the NT version, but I would prefer the RT version since it is more secure and gets automatic updates.

Hi Fred,



Thank you for posting your query on Microsoft Community.



I understand that you are facing issues associating a particular file extension with a program on Windows 10. I apologize for the inconvenience caused to you.

To assist you better, please provide the information:

When you say that "Default Program Associations", are you referring to the list of default applications in default programs settings?



I want you to be informed that all the file extensions is listed in the default program settings which is displayed under
Associate a file type or protocol with a program.



In default program list, all the programs or application will be listed. Then we can select each program as default program for opening a particular file.

I suggest you to refer to the below steps to make default program for a particular file extension.

1. Type "Control Panel" without the quotes in search box and click on it.

2. Click on Programs.

3. Then click on Default Programs and click on Choose Default for this Programs.

4. Select .flv file from the list.

Also you can try other steps to associate the a particular extenstion with the program.

1. Type "Control Panel" without the quotes in search box and click on it.

2. Click on Programs.

3. Then click on Associate a file type or protocol with a program
and search for .flv extension from the list.
