defragmentation

基本解釋

After the defragmentation is complete, Disk Defragmenter displays the results.
在Windows Vista系統(tǒng)中，沒有圖形用戶界面顯示進展，但您的硬盤驅(qū)動器仍在進行磁盤整理。整理完成后，磁盤碎片程序顯示整理結(jié)果。
The partition is then "frozen" (in other words, only the current number of extents will be considered for defragmentation).
然后分區(qū)被 “凍結(jié)”（換句話說，僅對當前數(shù)量的區(qū)段進行碎片整理）。
Merging extents to get fewer extents (defragmentation) is beneficial to customers who have a large number of extents in a partition and are likely to run into the partition page overflow problem.
對于那些在一個分區(qū)中存在大量區(qū)段，并且會遇到分區(qū)頁溢出問題的用戶來說，合并區(qū)段來減少區(qū)段數(shù)量（碎片整理）是非常有好處的。

Now defragmentation as an aside is not so much necessary these days because hardware has gotten so performance.
在硬件性能如此好的今天,碎片處理顯得并不是那么的重要。
