Register AnAction implementation and add it to group ProjectViewPopupMenu, then obtain currently selected file via com.intellij.openapi.actionSystem.CommonDataKeys#VIRTUAL_FILE.
Additionally, you can restrict visibility/availability of your action by checking ActionPlaces.PROJECT_VIEW_POPUP in update() method.
