I guess that you want to open the files with an editor. If I remember correctly (from a .properties editor example), your editor contribution should look like that:

<extension point="org.eclipse.ui.editors">
  <extensions>xyz,txt,jpg</extensions> <!-- .xyz .txt and .jpg files       --> 
  <default>true</default>              <!-- default editor for these types -->
