1, what is the use of disk defragmentation, then we first understand what disk fragmentation, the disk is like a large warehouse, which has many many rooms, and our files are like goods, may download 2 movies today, occupy 2 rooms, and delete one, only occupy a room, in download a very big game, The game will be empty room full use, such a complete game file in order to separate a film in the space, repeated deletion of the download on the formation of countless file files are inconsistent, this is the disk fragmentation
2, above I want to use their own words to explain, but it seems so messy, here to copy a more professional explanation
is when the middle of a cluster (composed of sector) content is deleted, a new write to a smaller file, so that there will be some space on both sides of the file, then write a file, any part of the two pieces of space can not accommodate the file, this time you need to split the file into two parts, the fragment formed a
3, because the file location is inconsistent, the disk read time increased, in the start of the game will be slow, big program open up cards. Slow copying of files
4, as if disk fragmentation is unavoidable, we for the computer running speed, we need to clean up the debris, although the computer configuration is very high, this impact is not very large,
5, Win7 began the system has been added to the very good disk defragmentation, as long as the set up a plan, the computer will automatically organize, such as the picture is a simple way to set up
6, SSD words please do not defragment Oh!
This only reduces the SSD life, in Win8 above system SSD system finishing function can only optimize can not be sorted to don't worry about
and XP to pay attention to Oh!
