How to use Ultimate Defrag LITE?

Possibly a few of you have this version. This is NOT the full feature version of UltimateDefrag. MegaScenery just sent it out with their Southern California scenery, which is how I obtained it. I've never used a 3rd party defrag program before. I know I want FSX running as close to the rim of the drive as possible... but I don't know how to set up the LITE program for the bet results.I don't know how to set the Auto Options dialong window. I read the Help file... but I still don't get it. Do I want to put the slider on the "Fast" side or the "Optimum" side or somewhere in between?Also should I select "Put directories close to MFT" or leave it unchecked?Thanks to anyone with experience on this.Steve
