You your are a Mac developer, artist or use different files types on your Mac you will know what life was like pre-Snow Leopard. A files created in an application would then re-open within that application using “creator codes”, simple. However with the release of Snow Leopard files now tend to open in all sorts of programs and mainly in the previewer.
Magic Launch is designed to bring back control to your files and allow you the ability to control which applications they open in.
Using a small preferences pane within magic launch you have the ability to set intercept commands every time a files is opened, redirecting to a location you choose. As its rule based the flexibility of the applications is extensive.
If you need to cover the control of your files Magic Launch is available for $13
