Windows XP (hereinafter referred to as XP) system takes up a lot of hard disk space, but many files are not necessary for the normal operation of the system, and not every user needs them, so we can manually "slim down" the system without using any software, which can save hard disk space and improve the running speed of the system.

First, clean up the document and set the directory.

"Documents and Settings" is a special directory in XP, which records some special file information of users. Let's see what can be deleted.

C:\ documents and settings \ all users \ application data \ Microsoft \ user account picture \ default picture

It is used when setting up an account or using MSN. These pictures are nothing special. You can delete them or replace them with your favorite pictures.

C:\ Documents and Settings \ User Name \ My Documents \ My Music

Most people will open a special place on the hard disk to store music, so delete it. One thing to note: if WMA files are played frequently, some music playing licenses will be downloaded to the local hard disk, and the system will put these licenses in this directory by default. If you see the License Backup directory in the directory, it is recommended to copy it to another location and change the path in WMP's Tools/License Management.

C:\ Documents and Settings \ User Name \ [Start] Menu \ Programs \ Accessories

This directory is a shortcut icon for some programs. There are few functions actually used in the attachment, and only Notepad and Windows Explorer are commonly used. Copy the required program shortcut icon to "c: \ documents and settings \ all users \ [start] menu \ Programs \ Accessories", and then delete this directory.

C:\ Documents and Settings \ User Name \ Favorites

The shortcut icons "MSN.com" and "Radio Guide" here, have you used these? Delete it if it doesn't work.

C:\ Documents and Settings \ User Name \ Favorites \ Links

As above, if you don't use it, you can delete this directory. Here you need to modify the registry to permanently delete the linked folder. Find the key "HKEY _ current _ user \ software \ Microsoft \ Internet Explorer \ toolbar" in the registry, and delete the value of "LinksFolderName" on the right.

Objective: To simplify the directory structure and program shortcut icons.

Second, program files can also be deleted.

"C:\Program Files" is familiar to everyone, because the default installation path is here when installing the program. See what can be deleted from it.

C:\ program file \Windows Update

This directory is used for online upgrade and can be deleted. As long as you log in to the upgrade website of Windows Update again to upgrade, this directory will be rebuilt automatically.

C:\ program file \ Windows Media Player \ skin

This is WMP's own "skin". I believe that many "skins" will not be used. It's best to leave only a few commonly used ones and delete the rest.

C: \ program files \ common files \ Microsoft shared \ stationery

This is the stationery pattern in Outlook. Keep what is useful and delete what is not. If you don't use Outlook to send and receive emails, delete them all.

Objective: To delete components that are not used in the program.

Third, the Windows directory can also be cleaned up.

Don't be intimidated by "C:\Windows", there are many things that can be deleted. In this directory, the file type is. BAK。 BMP，。 Old,. TMP "can be deleted. Except SchedLgU. TXT (for scheduler service). Txt "file can also be deleted. In addition, the clock.avi and Control.ini files can also be deleted without any impact on the system.

C:\Windows\$NtUninstall$

This is the directory automatically created by the system when upgrading Windows online, and its function is to facilitate the uninstallation of the installed system patches. If the patch runs normally, these directories are meaningless and can be safely deleted. You can uninstall these patches in Add or Remove Programs. Of course, the patch was not really deleted, but the "Add or Remove Programs" window became cleaner.

C:\Windows\Help

The first time you run Windows XP, you will always be prompted to run "Roaming Windows XP". The Chinese version uses a file in HTML format, only files, no sound. In fact, the roaming function in English is installed in the system. Although it is English, there is language, music and beautiful animation. It is the "tour.exe" in the "Tours/mmtour" catalogue. If it doesn't work, you can delete the whole directory of "Tour". Before that, you should delete the files in tourstrt.exe, tourW.exe and tourstart.exe in the "C:\Windows\System32\dllcache" directory.

C:\Windows\inf (hidden)

In this directory, you will see many files with the same file name and different suffixes, namely ". Inf "and" Pnf ",this is a precompiled file. Inf "file. If not ". Pnf "file, corresponding". , the pnf file will be created automatically. Inf file running. Therefore, everything. " The pnf file can be deleted.

(Display) After opening my computer, click the folder option in the tools in the project bar, click View in the pop-up dialog box, select Show all files and folders under Hide Files and Folders, and click Apply.

C:\Windows\Media

These are some MID and WAV sound effects that come with the system. You can keep what you like and delete what you don't like.

C:\Windows\Web

The "gif" and "htm" files here can be deleted. Look in the "Wallpapers" directory. Most of the desktop background that comes with the system is here. Anything you don't like can be deleted.

C:\Windows\System32

There are many folders named "1033", which mainly store system error reports, and most of them are empty folders, which can be safely deleted.

c:\ Windows \ System32 \ reinstall backups

There are many subdirectories here, which are the driver backups of the hardware in the computer. If you upgrade or replace a piece of hardware, and you are sure that you will not use the original driver, you can delete the corresponding directory.

Objective: To delete redundant backup files in the system directory.
