Consolidate Free Space Defragmentation method defragments all the files and consolidates free space, however file locations are not optimized. When you select the Consolidate Free Space option, the software will seek to create the largest possible extents of free space, and does not optimize file placement. This process can involve moving large files to reclaim relatively small amounts of free space (a maneuver that PerfectDisk omits when using SMARTPlacement by itself), and explains why this mode sometimes takes longer to complete. Free space consolidation is best for shrinking or growing disk partitions, when seeking to re-size virtual machines, or to provide a boost to lagging Windows performance when PerfectDisk itself recommends running this defragmentation algorithm.
