Introduction
The more you use your PC, the more it will collect odd files that you no longer need, taking up unnecessary disk space. It is therefore a good idea to regularly clean out your system, getting rid of the files you no longer need to make space for new ones.
You can also run maintenance programs which can 'defrag', or clean up, your files and arrange them in a way which makes it easier for your PC to find certain ones. By doing this, you can improve the speed at which Windows finds your files and runs your programs.
Before You Start
Although emptying redundant files and defragmenting your harddrive is common practice among most PC users, there is always the possibility that something may go wrong. It is therefore recommended that you make backups of important files such as those in your
My Documents folder before following these steps.
You should always be careful when deleting files you no longer think you need, and if you aren't sure it is probably best to leave them alone.
Your version of Windows may contain a
System Restore feature, in which case you can create a Restore Point to return to if you have any problems. Consult your Windows Help (click on the
Start menu then
Help and Support) for more information about this feature.
When running Disk Cleanup and Defragmenter, you should avoid having any other programs running at the same time.
The Recycle Bin
When you delete a file, don't forget that usually this just means it has been moved to the
Recycle Bin. If you do not regularly empty your Bin, the files inside may take up valuable disk space.
Double click the Recycle Bin icon on your desktop to see which files are currently stored in there. If there are any files in the Bin that you want to restore back to the original place you deleted them from, right-click on the files and select
Restore. If you are happy you no longer require any of the files in the Recycle Bin, you can remove them from your computer by right-clicking the Recycle Bin icon and selecting
Empty recycle bin.
You should empty your Recycle Bin regularly, say once a week.
Disk Cleanup
When working with programs, Windows stores information in temporary folders, but does not always clean them out afterwards, leaving behind unnecessary files. The
Disk Cleanup system tool allows you to clean out Windows components and programs you no longer need, and remove these temporary files.
From the Start menu, click on Programs> Accessories> SystemTools> Disk Cleanup. On newer versions of Windows, Disk Cleanup may now take a few minutes to compress files older than 50 days. The main Disk Cleanup window shows two tabs -
Disk Cleanup and
More Options.
In the
Disk Cleanup tab window, put a tick in the following boxes if you wish to clean out these unnecessary files:
- Downloaded program files
- Temporary internet files
- Recycle bin
- Temporary files
Click on the More Options tab and you can choose to get rid of unwanted Windows components, remove installed programs you no longer use, and remove all but the most recent System restore point.
When you have selected everything you want to clean up, click on
OK then
Yes to confirm you want to begin the Disk Cleanup process.
You should try to delete temporary files regularly, say once a week.
Defragmenting Your Hard Disk
Defragmenting your hard disk helps Windows arrange files in a way that makes it easier and faster for it to find your programs.
From the Start menu, click on Programs> Accessories> SystemTools> Disk Defragmenter.
It is recommended that you read the Defragmenter Help manual before beginning the defragmentation process. Click on Help from the menu at the top of the Disk Defragmenter window.
Please note that it is possible for 'defragging' your disk to take several hours if it is particularly fragmented, during which time you should not run any other programs.
Some important points from the Help manual to remember:
- Analyze volumes regularly and defragment them only when Disk Defragmenter recommends it. A good guideline is to analyze volumes at least once a week. If you seldom need to defragment volumes, analyze volumes monthly instead of weekly.
- If a volume has less than 15% free space, Disk Defragmenter will only partially defragment it. To increase the free space on a volume, delete unneeded files or move them to another disk.
To start the defragmentation process, click the volume that you want to defragment, and then click
Defragment.
