Microsoft Windows 2000 includes a built-in Disk Defragmenter tool. This tool excludes certain files because of known issues with moving these files. Also, files that are locked for exclusive use by another process are skipped.
The following files are permanently excluded from being defragmented. These files may be displayed in the analysis report as still being fragmented no matter how many times you defragment the drive.
Moving the following file can cause desktop problems, if the Recycle Bin or the Recycler folders are removed:
%SystemRoot%\ShellIconCacheMoving the following files (if present) can cause desktop problems:
Safeboot.fsThe following files are unmoveable system files. They are always displayed in green in the defragment analysis display:
Adjusting the MFTAlthough you cannot defragment the MFT once it becomes fragmented using the Disk Defragmenter, there is a way of preventing MFT fragmentation, or at least reducing the possibility of it becoming fragmented by reserving space for it ahead of time.
To determine how large the MFT is, how many fragments there are, and what percentage of the MFT is in use on an NTFS volume, perform a Disk Defragmenter analyze operation to generate a report. View the report and look for the following section under Volume Information:
Master File Table (MFT) fragmentation.Use this information along with the following article in the Microsoft Knowledge Base to adjust the NtfsMftZoneReservation value, back up and reformat the volume to create a contiguous MFT using the higher zone reservation space, and then perform a full volume restore:
Total MFT Size = 8512K
MFT record count = 8,504
Percent MFT in use = 99%
Total MFT Fragments = 4
