I wasn’t satisfied with windows defragment tool so I Googled little about possible replacements and among others found JkDefrag.
Here is a quote from web site of a JkDefrag:
JkDefrag is a disk defragmenter and optimizer for Windows 2000/2003/XP/Vista/2008/X64. Completely automatic and very easy to use, fast, low overhead, with several optimization strategies, and can handle floppies, USB disks, memory sticks, and anything else that looks like a disk to Windows. Included are a Windows version, a commandline version (for scheduling by the task scheduler or for use from administrator scripts), a screensaver version, a DLL library (for use from programming languages), versions for Windows X64, and the complete sources.
Program is very simple, just unzip and run it, no installation, no configuration and what is most important it works well.
On home page of JkDefrag you can download sources, executables and read some more info about it.
Read tips before defragmenting, they will increase speed of defragmentation.

I agree. I have tested several that says that defragmentation on the disk is ok but JKDefrag has lot to do after them.
Tnx for a comment.
