in windows 7, I want to open an MP4 file with a program I have installed on an external drive. Windows will not let me change the file association from media player. Even when I browse to the external disc it won't let me "Open with" that program. And it won't show that program in the list of options to "Open with". Is there a way doing doing what I'm trying to do?

You can't set a file association to a removable drive, as the application may not be present every time a file is double clicked. Only applications that are installed on an internal hard disk (or SSD) can be set as an association target.

Windows won't let you do that - or pin a removable program to the task bar in later versions - there isn't a way round that!

What you are saying makes sense and I'm sure that's why I can't make it work. However, .bin and .cdg are associated with the program on the external drive, and will open that program with a double click
