DISCFREE 

DISCFREE is a utility that reduces the amount of fragmentation on a disc.
Fragmentation is a term used to describe the extent to which files are
physically divided up on a disc.  As disc space becomes fragmented,
smaller and smaller amounts of contiguous space are available, and files
must be broken into smaller and smaller pieces to fit.  Fragmentation has
a negative effect on system performance and is highly undesirable.

You can use DISCFREE to:

   *   Determine free space on the disc.

   *   Perform a START NORECOVERY to correct fragmentation.

   *   Obtain a detailed format of free space (HISTOGRAM) or free space
       allocation (ALLOCATION) on discs.

For more information on using DISCFREE, refer to Volume Management 
(32650-90045).
