Fragmentation Analysis

Use the Fragmentation Analysis to analyze individual disks on your 
computer.  By running the Fragmentation Analysis both before and 
after running Diskeeper®, you will be able to see the actual reduction 
of file fragmentation.  

When the Fragmentation Analysis is started, you are first given the 
opportunity to select the disk to be analyzed.  Highlight the letter 
corresponding to the drive you want to analyze, then choose Start.  
Fragmentation Analysis can only be run on local disks.  It cannot be 
run across a network.

The Fragmentation Analysis display contains the following information:

Disk
----

This section of the Fragmentation Analysis display shows which disk 
drive is being analyzed.

Disk Size
---------

This section of the Fragmentation Analysis display shows the total size 
of the disk.  This includes files and free space.

Total Free Space
----------------

This section of the Fragmentation Analysis display shows the total amount 
of free space on the disk.

Cluster Size
------------

This section of the Fragmentation Analysis display shows the cluster size 
for the disk.  A disk cluster represents a number of disk sectors treated 
as a single unit. The entire disk is divided into clusters, each one a 
minimum increment of storage.

Number of Files Checked
-----------------------

This section of the Fragmentation Analysis display shows the total number 
of files on the disk.  This number does not include zero-length files, or 
files less than one cluster in size on NTFS partitions.

Average File Size
-----------------

This section of the Fragmentation Analysis display shows the average size 
of all the files on the disk.  This number does not include any zero-length 
files or pagefiles.

Total Space Used
----------------

This section of the Fragmentation Analysis display shows the total amount 
of disk space (in kilobytes) currently occupied by files.

Percent Space Used
------------------

Once the analysis is complete, this section of the Fragmentation Analysis 
display shows the percentage of disk space in use.

Number of Fragmented Files
--------------------------

This section of the Fragmentation Analysis display shows the total number 
of fragmented files on the disk.

Number of Excess Fragments
--------------------------

This section of the Fragmentation Analysis display shows the number of 
excess, unnecessary fragments on the disk.  Contiguous files are not 
counted in this total.

Percent of Disk Fragmented
--------------------------

This section of the Fragmentation Analysis display shows the percentage 
of the disk that contains fragmented data.  For example, a figure of 33% 
indicates one-third of the disk contains fragmented files.  This figure 
is a good overall indication of the state of fragmentation on the disk.

Average Fragments per File
--------------------------
This section of the Fragmentation Analysis display shows the average 
number of fragments per file on the disk.  This is an index of how 
fragmented the files on the disk are.

If the average fragments per file is 1.00, the files are contiguous.  
If the figure is 1.10, then 10% of the files, on average, are in two 
pieces.  1.20 means 20%, 1.30 means 30%, etc.  A figure of 2.00 means 
the files average two fragments each.  1.00 is the best figure attainable, 
indicating that all files or nearly all files are contiguous.

Largest File
------------

This section of the Fragmentation Analysis display shows the directory 
path and filename of the largest file on the disk, and the size of that 
file.

Most Fragmented File
--------------------

This section of the Fragmentation Analysis display shows the directory 
path and filename of the most fragmented file on the disk, and the number 
of fragments the file is in.  If this file is one that users access 
frequently, the impact to your system performance may be greater than 
indicated by the Average Fragments per File figure.
