List of all applications that process the specified file type

Is it possible to list all applications on a machine that can open a specific file type using only the file extension? for example, if I have a text file (.txt), I want a list of all applications that can open .txt files.

Check the beehive HKEY_CLASSES_ROOT

in your registry. It's all there.

There is no master list of every application that can open a specific file that I know of.

I assume you are talking about windows machines ...

You can only assume that the list of registered applications can handle a specific file extension (the same applications that appear when you right-click and select "Open With"). It's somewhere in the Windows registry.

I would suggest you check the microsoft documentation or open the registry and start looking for known extensions.
