DEFRAGMENT, FILE, Qualifiers, /BRIEF
 *Conan The Librarian 

       /BRIEF (default)
       /NOBRIEF

          The /BRIEF qualifier is used only with the /LOG
          qualifier. The /BRIEF qualifier requests a brief log
          of all actions taken by the defragmentation process.
          This log includes beginning and ending file status
          information. The /BRIEF and /FULL qualifiers are
          mutually exclusive, and /NOBRIEF produces the same
          result as /FULL. The /BRIEF qualifier is the default.
