This paper provides an overview of the differences between PerfectDisk and the Windows 7 defragmenter based on key areas of functionality and defragmentation methods. The process of comparing two utilities that perform a similar function (i.e. disk defragmentation) is not necessarily a case of comparing "Apples to apples," as the two utilities' philosophies and strategies, and most importantly results, differ substantially. To assert that "All defragmenters are the same" is a gross oversimplification of the issues surrounding disk defragmentation. Sure, data files need to be defragmented; but equally important is the treatment of the remaining free space.
