The amount of free space is very important when running Disk
Defragmenter. A
minimum of 15% is required but sometimes 20% is desirable if the drive /
partition
contains one or more large files. You can run Disk Defragmenter a second
and third
time if files are still fragmented after the first run. You can put
files more prone to
fragment in their own partitions.
If you use Outlook Express regularly compacting Outlook Express before
running
Disk Defragmenter is helpful.
Disk Defragmenter provides a "Most fragmented files" list. When a
fragmented file is
larger than the largest pocket of free space available then the files is
not fragmented.
Running Disk Defragmenter a second or third time does move files around
and can
reduce / eliminate the contents of the "Most fragmented files" list. The
more free
space on the drive / partition, the more likely it is that all fragments
will be
eliminated.
Free space cannot be defragmented with the Windows XP Disk Defragmenter.
Neither can your pagefile cannot be defragmented because the file is in
use whilst
Disk Defragmenter is running. You can purchase other Defragmenting
Utilities e.g.
Perfect Disk, which will defragment your pagefile and free space.
Another option is to
place your pagefile in it's own partition. A pagefile partition is best
located as the first
partition on a second hard drive. You should leave a small page file at
the original
location.

There are few files which Disk Defragmenter does not defragment. The
most significant is the MFT (Master File Table ), which remains in 2 / 3
fragments.
