You can create an association in your OS for any given file extension. By associating each module of the Authoring Tools to each file extension, you should be able to double click an .edm file and directly open it in the Emotional Decision MakingWF.
However, after this association, when opening a file, it launches the application without opening the specific file. To clarify, the correct auth tool is launched without any opened file and we must manually open it inside the AuthTool.
This small improvement may prove quite useful.
