Magic Launch for Mac

From Metakine:

Take true control over which application is launched when you double-click a file. With Magic Launch, you can reinstate creator codes on a per file-type basis. Or create personalized rules to select a different application depending on the folder the file is located in, the color label of the file, its name, or its content.

Save time by making files launch automatically the right application and concentrate on your work.

Magic Launch does not hack your system in any way, it just changes the default application for the selected file types to Magic Launch's dispatcher agent. The Magic Launch Agent runs only when needed, and closes immediately once the file is open so it doesn't not consume any resource on your system while you do other things. It is also possible to run a terminal command instead of an application.
