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.

用這個軟體來取代 Windows 的 defragmenter 很久了，是一個很穩定的軟體，使用也很容易，只要打開軟體即開始執行，重組整個硬碟，不需要任何設定。你可以用睡覺的時間讓它跑到天亮，不用再選哪一個硬碟要重組，另一個優點是你可以隨時關掉，不會傷害你的磁碟，所以它也有螢幕保護模式，也就是當進入螢幕保護模式時，就會自動開始重組，很方便。不過我通常都是看自己的需要，自己打開程式重組。
