Lesson 23. Disk Management > Defragmenting Your Disk

Defragmenting Your Disk

When a file is stored to a disk, it's broken into chunks, and each piece is stored in the first available sector. After the disk starts getting full, and files are deleted (making certain sectors available), file parts are no longer saved in adjacent sectors.

Thus, a file may be scattered (or fragmented) over the disk, which can slow down its retrieval of files. To improve the speed of your PC, you should defragment your hard disk. Defragmenting reorganizes the parts of each file so that they are once again adjacent to each other on the hard disk, eliminating excess search time.
