Say I have mp3 music in directory 'A' which I want to open with iTunes. And I have some more mp3 files in directory 'B' which I want to open with VLC player.
How can I set the default 'application' for each set of files and store it permanently in OSX Mavericks? The idea of having a single application type per extension and using 'open with' is too painful to use on a repeated basis.
(Now, answering the 'why' - to be honest, I dont have this requirement with mp3 files but with source code from different projects. Due to project specific requirements, certain application works best for a source file in project 'A' and another application works right in project 'B')
