Jenny,
Thank you for your reply.
After using Window's Disk Defragment, I print a report that describes files
that could not be defragmented. Following are some of the details:
Volume Size = 14.65GB
Cluster Size = 4 KB
Percent Free Space = 25%
Total Fragmentation = 17%
File Fragmentation = 34%
Total Fragmented files = 6
Pagefile fragments = 1
Fragmented folders = 1
Total MFT Fragments = 2
Files that could not be defragmented:
\WINNT\SchCache\(FQDN) 19 fragments, 974KB
\Program Files\Exchsrvr\MDBDATA\priv1.stm 182 fragments, 740MB
\Program Files\Exchsrvr\MDBDATA\priv1.edg 264 fragments, 953MB
Please advise your recommendations; should I run the tool for Exchange
defragmenter?

> of files or folders, so be sure to analyze volumes after this happens.
> Generally, volumes on busy file servers should be defragmented more often
> than those on single-user workstations.
>
> - Ensure that your disk has at least 15% free space
>
> A volume must have at least 15% free space for Disk Defragmenter to
> completely and adequately defragment it. Disk Defragmenter uses this space
> as a sorting area for file fragments. If a volume has less than 15% free
> space, Disk Defragmenter will only partially defragment it. To increase the
> free space on a volume, delete unneeded files or move them to another disk.
>
> - Defragmenting during low-usage periods
>
> Defragment file server volumes during low-volume usage periods to minimize
> the effect that the defragmentation process has on file server performance.
> The time that Disk Defragmenter takes to defragment a volume depends on
> several factors, including the size of the volume, the number of files on
> the volume, the number of fragmented files, and available system resources.
>
> - Defragmenting after installing software or installing Windows
>
> Defragment volumes after installing software or after performing an upgrade
> or clean install of Windows. Volumes often become fragmented after
> installing software, so running Disk Defragmenter helps to ensure the best
> file system performance.
