- 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.
