| − | ====My model is compared as a text-file, how can EMF compare know what file it should handle ?====

| − | '''Q''' : My model is compared as a text-file, how can EMF compare know what file it should handle ?
| + | |
| − | | + | |
| − | '''A''' : EMF compare uses a content-type to know if it should be started or not. By default this content-type is composed of *.ecore and *.uml file but you may add your own extension using the <tt>Preferences view / Global / Content-types</tt> and adding your file extension in the "Model File" content-type.

| − | '''A''' : Using the "Model File" content-type defined with EMF Compare, here is a sample from a plugin.xml:
