Not for OS X. Plus Optimizer came with older versions of Disk Warrior, but Plus Optimizer runs in OS 9 only and is no longer included with Disk Warrior. Don't be confused by the fact that Disk Warrior says that it is "defragmenting" or "optimizing" your Directory. That isn't the same thing as defragmenting your hard drive. Randy B.
