I believe everyone has heard of disk fragmentation, so-called disk fragmentation, in layman's terms, refers to the computer's various files at the beginning of storage in the disk when the address is connected together, but with the file read and write, or many times the operation of the mobile copy, these files on the disk address is not continuous, These discontinuous files become disk fragments, the result of discontinuity is to let your computer read and write files slow, so today to share a
A disk tool designed for NT/2000/XP/Vista,
Supports almost all file systems, including fat16, FAT32,
NTFS, ntfs5, FS (encrypted file system) and so on, is a rare good tool. Yes
The hard disk is automatically reorganized at the specified time, and long Chinese file names are supported.
O O defrag Professional Edition supports the following operating systems:
+ Windows NT 4.0 Workstation (SP6 or above)
+ Windows 2000 Professional
+ Windows XP Ho
It is well known that the system will cause disk fragmentation after running for a while, which can seriously affect the speed of the system, so Windows system itself provides the defrag command to help users clean up disk fragmentation, Windows 7 is no exception, and Vista is different from windows The defrag in 7 adds more options, with command line versions containing more directives.
Disk defragmentation is a very useful feature, especially for long-used systems, as well as some computers that frequently delete files, and it is necessary for the system to defragment the disk at regular intervals. This allows you to sort out some of the file fragments and delete them.

Defrag: Defragmentation of disk
[applicable] disk reads and writes many times, or the disk uses the time to be very long, may need to use this commandDefragment the disk. Disk fragmentation does not mean that the disk is broken, but only because of multiple copies and deletionsIn addition to files, disk usage can be very incoherent, causing slower speed.
