Presently the jD content plugin show the Download title as the link. 
Many people like to have theier own text such as  'click here' or similar.  Users also recognise such a phase.
It would be an enhancement to extend the plugin to support say  {jd_file file==31 text=='click here'} or similar.If the text== was absent or was written text==''  then the Download Title would be used.
