How to clean disk

Start the Disk Cleanup program by clicking the Start button and then selecting programs → attachments → system tools → disk Cleanup menu items.

The system then pops up the Select Drive dialog box, from which the user can select the partition that needs to be cleared and click the OK button.

The Disk Cleanup automatically finds the various unwanted files on the partition, such as temporary files downloaded by Internet Explorer, files in the Recycle Bin, temporary files in the Temp folder, and so on, and displays the various unwanted files found in the List window.

Finally, the user can choose the file to be deleted from the list of the given junk files according to their actual situation, and then click the OK button, the Disk Cleanup program will automatically remove them and free up disk space.

You can also click the Other Options tab of the Disk Cleanup program, and then expand the disk space by removing some windows parts, uninstalling the installed applications, and so on.

A built-in tool in the Windows XP operating system, three ways to more effectively maintain your computer's performance.

First, free up disk space

By freeing up disk space, you can improve your computer's performance. The Disk Cleanup tool is a utility that comes with Windows to help you free up space on your hard disk. The utility first identifies files that can be safely deleted, and then allows you to select the files that you want to delete or all of them identify.

Disk Cleanup Tool Features:

• Delete temporary Internet files.

• Delete the downloaded program files.

• Empty the Recycle Bin.

• Delete Windows temp files.

• Remove optional Windows components that are not used.

• Remove Programs that are installed but no longer in use.

Tip: Typically, temporary Internet files occupy most of the space, because in order to speed up later access, the browser caches every page you visit.

Using the Disk Cleanup tool

1. Click Start, point to All Programs, attach to attachments, System Tools, and then click Disk Cleanup. If you have more than one drive, you are prompted to specify the drive you want to clean.

2. In the Disk Cleanup for (drive) dialog box, scroll to see the contents of the files to delete list.

3. Clear the check boxes for the files that you do not want to delete, and then click OK.

4. When you are prompted to confirm that you want to delete the specified file, click Yes.

After a few minutes, the process completes, the Disk Cleanup dialog box closes, and your computer is cleaner and performs better.

Second, speed up data access

Disk fragmentation can degrade the overall performance of the system. If the file is stored on a different fragment, the computer must search the hard disk when the file is opened to bring the pieces back together. The response time may become significantly longer.

Disk Defragmenter is a Windows utility that merges files and folders stored on different fragments on your computer's hard disk so that either of these files and folders occupies only one space on the disk. The disk reads and writes faster when the files are stored neatly at the end of the file without fragmentation.

When to run Disk Defragmenter

In addition to running Disk Defragmenter regularly (preferably once a month), in addition to the usual monthly routines, you can run the utility if certain events occur.

You should run Disk Defragmenter in the following situations:

• Added a large number of documents.

• Only about 15% of available disk space.

• A new program or a new version of Windows is installed.

To use Disk Defragmenter:

1. Click Start, point to All Programs, attach to attachments, System Tools, and then click Disk Defragmenter.

Click ' Analyze ' to start the Disk Defragmenter

2. In the Disk Defragmenter dialog box, click the drive that you want to defragment, and then click the Analyze button.

After the disk is analyzed, a dialog box appears telling you whether the drive being analyzed should be defragmented.

Tip: Before defragmenting a volume, you should analyze it to see how long the defragmentation process might take.

3. To defragment one or more of the selected drives, click the Defragment button.

After the defragmentation is complete, Disk Defragmenter displays the results of the collation.

4. To display detailed information about a defragmented disk or partition, click View Report.

5. To close the View Report dialog box, click Close.

6. To turn off the Disk Defragmenter utility, click the Close button on the title bar of the window.

Iii. Detecting and repairing disk errors

In addition to running the Disk Cleanup tool and Disk Defragmenter to optimize your computer's performance, you can also run the error checking utility to check the integrity of the files stored on your hard disk.

A bad sector may appear when you use a hard disk drive. Bad sectors can degrade hard disk performance and sometimes make it difficult or even impossible to perform data writes, such as file saving. The error checking utility scans the hard drive for bad sectors and scans for file system errors to see if certain files or folders are misplaced.

If you use your computer every day, try running this utility once a week to help protect you from data loss.

To run the error checking utility:

Important: Be sure to close all files before running the error checking utility.

1. Click Start, and then click My Computer.

2. In the My Computer window, right-click the hard disk for which you want to search for bad sectors, and then click Properties.

3. In the Properties dialog box, click the Tools tab.

4. Click the "Start Check" button.

5. In the Check Disk dialog box, select the scan and attempt to recover bad sectors check box, and then click Start.

In most cases, check "scan and attempt to recover bad sectors"

6. If a bad sector is found, please choose to fix it.

Tip: If you think your disk contains bad sectors, select the Automatically fix file system errors check box.

Open My Computer, right click on the C disk-> left-click Properties, so you can see the C disk space usage, the same way to open the other disk to see the use of the disk, so you can determine the disk of your computer occupied space and the remaining space, rather than estimate.

Only by determining the use of the disk in order to "thin" the computer, that is, by removing some unnecessary software, files to free disk space.

You have said that you often download and install some software, so I estimate your computer system automatically create more restore points, you can remove the System Restore point (only the most recent restore point), to release the C disk space, the effect is very obvious.

Of course, you can use some special tools like Windows Optimization Master, Super Bunny, etc., optimize your computer, clean up the registry, and clean up the garbage files to free up disk space.

In Windows, the user can choose program/attachment/System Tools/Disk Defragmenter from the Start menu, eject the Select Drive window, select the partition to defragment, and then click OK to start sorting, but the defragmentation process is time-consuming, General 2GB or so the zoning needs more than 1 hours, so recommended:

1, when defragmenting the disk, to close all other applications, including screen saver, it is best to set the size of virtual memory to a fixed value. Do not read and write to the disk, once disk defragment found that the file has changed, it will restart the collation.

2, defragment the frequency of the disk to control the appropriate, too frequent collation will shorten the life of the disk. Frequently read and write disk partitions are collated once a week.
