If you miss the map,
advanced settings, or detailed reporting of the old-school defragmenters,
check out PerfectDisk (http://raxco.com/, shown in Figure 5-10). It??™s not free,
but there??™s a time-limited demo on the Raxco web site.
There??™s not a whole lot in the way of free defragmenters, but Auslogics Registry
Defrag (http://www.auslogics.com/registry-defrag/) promises to improve
Windows performance by shrinking and optimizing your Registry.

Performance
Command-line defragmenter
As it turns out, Vista??™s own Disk Defragmenter isn??™t quite as feeble as it first
appears. Although it doesn??™t offer anything close to the usability of Perfect-
Disk, there is a little-known command-line version (defrag.exe) that gives
you just a little more freedom than the one you access through Windows
Explorer.
Open a Command Prompt window in administrator mode (right-click the
Command Prompt icon in the Start menu and select Run as administrator),
and then type the following at the prompt:
defrag -a -v c:
and press Enter to generate a report like the one in Figure 5-11.
To perform a full defragmentation (the default is only a partial defrag), type:
defrag -w c:
Press Ctrl-C at any time to interrupt Defrag. Or, to perform a full defragmentation
of all the drives on your PC, while forcing defragmentation on
nearly full volumes that would otherwise be skipped, type:
defrag -c -w -f
For more options, type defrag -? at the prompt and press Enter.
