In particular, this includes the registry, page file and hibernation file.

It does not defragment files residing in the Recycle Bin or files that are in use.

In Windows 2000 and later operating systems, Disk Defragmenter has the following limitations:

Making files contiguous so that they can be read without unnecessary seeking.

Obeying a user-provided table of file descriptions to emphasize or ignore.

Moving infrequently used files further from the directory area.

one third of the way in, so that average head travel to data is halved compared to having directory information at the front. Moving this spot into the center of the data, i.e.

Moving all the index or directory information to one spot.

The Disk Defragmenter in Windows 2000 was a stripped-down licensed version of Diskeeper, licensed from Diskeeper Corporation. This version had the limitation that if the contents of the drive changed during defragmentation, it rescanned the drive and restarted the process from where it left off. It could be scheduled using a Maintenance Wizard and supported command line switches. Debutĭisk Defragmenter also shipped as part of Windows 95, Windows 98 and Windows Me.

However, Windows NT 4.0 did not provide a graphical or command-line user interface. Microsoft included file system control (FSCTL) commands to move clusters in the Windows NT 4.0 kernel, which worked for both NTFS and FAT32 partitions.

Executive Software, later renamed Diskeeper Corporation, released Diskeeper defragmentation software for Windows NT 3.51, which shipped with a customized version of the NT kernel and file system drivers that could move clusters. Versions through Windows NT 3.51 did not have an application programming interface for moving data clusters on hard disks. Initial releases of Windows NT lacked a defragmentation tool. Windows NT, however, did not offer a Defrag utility, and Symantec was suggested by others as a possible alternative for the utility. Several third party software developers marketed defragmenters to fill this gap. Microsoft's MS-DOS did not defragment hard disks.

As early as the end of 1982, the IBM PC DOS operating system that shipped with early IBM Personal Computers included a Disk Volume Organization Optimizer to defragment the 5¼-inch floppy disks that those machines used.
