NOTE: You can use your computer while Disk Defragmenter is running. However, your computer operates slower and the defragmentation process restarts if the contents of the drive you are defragmenting changes.
To start the Disk Defragmenter tool, use the following steps:
- Click Start, point to Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.
- Click the drive you want to defragment, click OK, and then click Yes.
