Disk Defragmentation Tool

Defraggler is a file and/or disk defragmentation tool. It defrags
individual files, defrags entire drives, analyzes fragmented files/drives,
checks drives for errors, provides a visual display of entire disk
(drive map), has a progress indicator, includes update checking, and more.
This is an excellent way to defragment (defrag) your files and therefore
speed up Windows considerably. Because it can work with individual
files you don't need to defrag an entire drive just to bring one errant
file under control. Possibly the best part of the program is the full
analysis of all the fragmented files on a drive, their size, and even the
number of pieces that the file is fragmented into. Like most defrag
tool, Defraggler is not happy working with Windows files because Windows
protects its own files against sabotage and it cannot differentiate
between sabotage and a legitimate function (like defragmentation).
