Diskeeper 10 User's Manual

14 Overview of Diskeeper
defragmentation alone. This is the first industry implementation of “Disk Performance Calibration”, the modern
evolution of the outdated and inconclusive disk optimization strategies of the past.
Exclusion Lists—Diskeeper exclusion lists allow you to specify files and directories that will not be allowed to
be processed by Diskeeper.
Event Logging— Diskeeper records information about its activity in two ways. First, general information
about previously-run defragmentation job is shown in the Job Log tab within the Diskeeper console. Additional
information can also be stored in a log file. A wide variety of information can be saved for future reference.
Simultaneous Analysis or Defragmentation Operations—You can analyze and/or defragment more than one
disk volume at a time. Different Diskeeper editions support different numbers of simultaneous operations. See
Appendix A for more information.
Boot-Time Defragmentation—Defragment files at boot-time that cannot be moved safely when Windows is
running.
Group Policy Support—Diskeeper can be configured network-wide with the Group Policy Editor provided
with Windows 2000 Server and Windows Server 2003.
Other Things to Know
• When running Diskeeper in the Set It and Forget It or Manual Defragmentation modes, you can run other
tasks while defragmentation is occurring.
• When Diskeeper runs at higher priority levels, performance of other active processes will usually be
affected.
• When Diskeeper runs at lower priority levels, defragmentation may take longer, since Diskeeper "backs
off" for higher-priority processes, including screen savers.
• With the exception of boot-time operations, Diskeeper runs as a Windows Service and it optionally logs
useful defragmentation information into either the Windows Application Event Log (under Windows NT,
Windows 2000, Windows XP and Windows Server 2003) or to a text file (under Windows 98/Me).
• Diskeeper can be uninstalled in the standard manner using the Add/Remove Programs applet in the
Windows Control Panel.
• Due to limits built into the Windows NT/2000 file systems, Diskeeper cannot defragment files on NTFS
volumes with a cluster size greater than 4KB (4096 bytes), except during Boot-Time Defragmentation.
This limitation has been removed in Windows XP and Windows Server 2003, where Diskeeper can
defragment NTFS volumes with cluster sizes of up to 64 kilobytes. Note the boot-time defragmentation
operations are not affected by this limit.
• You must be logged into an account that is a member of the Administrators group to run Diskeeper on
Windows NT, Windows 2000, Windows XP and Windows Server 2003 systems.
• Diskeeper relies on the Microsoft Management Console (MMC), which is available for Windows 98. The
MMC is built into Windows 2000, Windows XP and Windows Server 2003. For more information about
the MMC, see the Glossary.
Exclusion List
In some cases, you may have files or directory folders you do not want to defragment. For example, you may
not want to defragment temporary files that will soon be deleted. Any files or directories can be excluded from
Diskeeper processing by adding them to the exclusion list.
