Thanks for the linfo. I did have the options checked, but I have not done a boot defrag. What I have done is: defragged the fragmented files (5) and managed to defrag four of the five. The program aborts at the pagefile.sys file. I've added this to the exclude list, but it still aborts at this file. I have managed to get it to 8% fragmented so I'll either live with it or try something else.
