I of course know how to change the default application which opens a file type. For example, in the File Type column of Windows Explorer, it can say FooType, since I associated it with the application Foo to open it. However, here is the challenge: what if I want the File Type displayed to be different than the name of the application which is set to default open it?
Specifically: We use JRiver Media Center. If I want JRiver to open both MP3 and FLAC as default, it displays file type as Media Center File. However, in Windows Explorer, I can't tell the difference between FLAC and MP3 without looking at the long file name, and I of course cannot sort by FLAC or MP3 because they are both listed as Media Center File. I do not see a column heading for simply Extension.
Suggestions? How can I have JRiver as the default application to open both FLAC and MP3 yet also be able to sort by those file types in Windows Explorer?
