Windows 10: How can I associate a file extension to an app which is not listed

Background: trying to get a new Windows 10 Pro computer set up to, as closely as possible, do everything my Windows 7 one could (I'm an eternal optimist). I'm old enough to be quite conversant with BASIC programs, and have "installed" "QB64" on the new computer. I put quotes around "installed" since all you do is download the program and put the ".exe" file in a folder in Program Files -- there's no actual installation process. Therefore Windows 10 (apparently) doesn't know it's there, and doesn't offer it to me to associate with a ".bat" file. Any way I can achieve this association?

File extension not in file association list


I could not use the below instructions, as I am trying to change a common file type (.tif) to an application not appearing in the standard list (Microsoft's attempt to lock out competitive apps perhaps?). Just go to the file with extension that you want to open, in the File Explorer utility, right click and select "open with". Then look for your preferred app in the "other apps" list and make sure "use as default" and your are all set.

 

File extension not in file association list


Hello, I use Notepad++ to edit Python files which have the file extension .py such as "sample.py"

I would like to set Notepad++ as the default program to open .py files.

When I open a .py file I get the popup asking me which file I want to use to open. But I do not get the choice to set the default program to open this extension.

When I go to Settings|Choose Default Apps By File Type the .py extension is not listed.

Looking through the registry I see that there is no .py handler.

Q: What is the method to manually add a file extension and associate it with a program?

Thanks!

 

Can a file extension(.flv) be added to Default Program Associations.

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.

4. Click on .flv and then click on Change Program.
