title: How can I override a default file extension for Notepad++?
body: <p>I want to open iOS objective-c files in Notepad++ (with a .m extension) and have it designated as an Objective-C file. In settings --> style configurator, I know that I can add a "user ext." (m) for Objective-C. The problem is that Matlab already uses the .m extension as the default extension field, which can't be edited. Is there a file I can access to change this?</p>
