Defrag

Instructions
1
Click "Start" and select "Al Programs."

2
Select "Accessories and choose "System Tools."

3
Click "Disk Defragmenter."

4
Select the hard drive you want to defrag and click "Analyze." This will cause Windows to do a rough analysis of the file system and report how fragmented the file system is, given as a percentage.

5
Decide whether or not to continue with the defrag process, depending on the results of the analysis. If the file system is not very fragmented, such as 2 or 3 percent, Windows will report that you do not need to defragment at this time, although you still have the option to do so.

6
Click the "Defragment Disk" button.

     Click "Disk Cleanup" in the "General" tab of the opened "Properties" window. The amount of space you will be able to free up is calculated for you. Depending on how much clutter is stored on your computer, this may take close to a minute to calculate.
