DEFRAGMENT

     Invokes the Disk File Optimizer. This utility is a layered
     product that restores file contiguity while the target volume
     remains on line and accessible. The Disk File Optimizer is
     compatible with any Files-11 structure level two (ODS-2)
     formatted volume including single volumes, bound volume sets,
     stripe sets or shadow sets. The file defragmentation utility
     is also compatible with ODS-5 formatted device on OpenVMS Alpha
     7.2-1 and above.

   Look for a DFGxxx kit, and install it.  You need a version
compatible with your VMS version, but I'd expect the Hobbyist
kit to offer compatible components.

      HELP DEFRAGMENT

   More fun: DEFRAGMENT /INTERFACE=DECWINDOWS

   But I'd worry about many things before I started worrying
about disk fragmentation.
