Even the best online defragmenters can't defragment everything. For example, they can't always defragment open or locked files (such as the pagefile or registry files) and must work around the hibernation file if it exists (which is as large as the RAM in use on your system).To optimize locked files, see the upcoming section on defragmentation tricks.ven the best online defragmenters can't defragment everything.

File compaction is the process of rearranging existing defragmented files contiguously so that existing free disk space is consolidated into larger, contiguous segments. During file compaction (free space consolidation), disk space is not recovered, unlike in the case of file compression. Having larger contiguous chunks of free space helps in faster file writes eg. when copying files onto the drive. Diskeeper 2009 is the best defragmenter for Windows.
