Most defragmentation tools only let you defrag the whole drive.
Defraggler gives you the power to select individual files and folders
to defrag. So you can get the job done in seconds, rather than waiting
for the whole drive to complete. Of course if you want to defrag the
whole drive Defraggler will let you do that too.
Just extract onto USB and run.
Tested and work on Windows XP SP3.
