After deleting the above files, the space of drive C will be greatly increased and the machine will be faster. In addition, you must sort out disk C, start-programs-accessories-system tools-
Disk defragmentation; Clean the disk after completion: Start-Programs-Accessories-System Tools-Clean the disk; Create a system restore point after completion: Start-Programs-Accessories-System Tools-System Restore (create restore point). Then turn off system restore. In the future, if your system has problems, we can use System Restore to restore to the state before the newly created restore point.
12, uninstall some unused components (such as MSN, Outlook Explorer, etc. ) and close the "Error Report" that is useless to us: My Computer-Properties-Advanced-Click "Error Report" and select "Disable" in the pop-up "Error Report" dialog box. Press "OK".
After the above processing, the space of disk C will be much larger. You try
In addition, system recovery, virtual memory, standby hibernation, etc. will occupy system space.
System disk cleaning method

The following is for your reference
1. Delete unnecessary files in the system.
(1) Delete system file backup
In the "system32\dllcache" directory of system files, there are nearly 250MB files, namely Windows? Backup of XP system files. When the system files of Windows XP are replaced, deleted or modified, Windows XP can automatically extract the corresponding system files for recovery, thus ensuring the stability of the system. You can't delete the folder directly, but you should enter the Sfc.exe/Purge cache command at the command prompt to clear it.
(2) Delete the driver backup
Delete the Driver.cab file in the "driver cache\i386" directory in the Windows XP system directory, which saves the backup of hardware drivers and is generally unnecessary. Even if you need to install new hardware, you can insert the installation CD of Windows XP into the CD-ROM drive.
(3) Delete useless input methods
There are files related to input methods in the "Windows\ime" folder, among which traditional Chinese, Japanese and Korean input methods are useless to most of us. We can delete three directories, namely "chtime", "imjp8_ 1" and "imkr6_ 1", which are traditional Chinese, Japanese and Korean input methods respectively.
(4) Delete the help file
At the beginning of using Windows XP, the system help is very useful, but as you become more familiar with the system, the help file becomes more and more redundant, so you can consider deleting it. XP Help files are stored in the Help folder under the system installation directory, and all files and directories can be deleted.
2. Reduce the hard disk space occupied by the system.
(1) Turn off system restore.
System restore can make the computer go back to an earlier time (called restore point) without losing our recent work, but it will take up a lot of hard disk space for a long time. Therefore, manual setting is needed to reduce the hard disk occupation.
Open the System Properties dialog box, select the System Restore tab in the dialog box, and select the Turn off System Restore on All Drives check box to turn off System Restore. If you don't turn off the system recovery function, you can set recovery only for the disk or partition where the system is located. First, select the partition where the system is located, click the "Configure" button, and cancel the "Turn off system restore of this drive" option in the pop-up dialog box, then you can set the disk space for system restore.
2) Turn off hibernation support
Hibernation takes up a lot of hard disk space. If you use less, you might as well turn off * * *. To turn it off, open the Control Panel, double-click Power Options, select the Hibernation tab in the pop-up Power Options Properties dialog box, and uncheck the Enable Hibernation checkbox.
(3) reduce or prohibit virtual memory
When the physical memory of the system is relatively large, you can consider reducing the value of virtual memory or even canceling it. When you have 5 12MB of physical memory, you can set the virtual memory to half of the physical memory, that is, 256MB. If you have 1GB of physical memory, you can cancel the virtual memory.
For the setting method of virtual memory, please refer to "Reasonable Setting of Page Virtual Memory".
Clear temporary files
(1) Clear temporary system files.
The temporary files of the system are generally stored in two locations: a temp folder under the Windows installation directory; The other is the X:\Documents and Settings "user name" \Local Settings\Temp folder (x: the partition where the system is located). Files in both locations can be deleted directly.
(2) Remove temporary Internet files
Long-term surfing the Internet will produce a large number of temporary surfing files, and regular deletion will save a lot of hard disk space.
Open IE browser, select Internet Options from the Tools menu, select the General tab in the pop-up dialog box, click the Delete File button in the Temporary Internet Files column, select the Delete All Offline Content check box in the pop-up Delete File dialog box, and click the OK button.
You can also set the disk occupied by temporary network files within an acceptable range, click the "Settings" button in the "Temporary Network Files" column, and then set the disk space occupied by temporary network files in the "Settings" dialog box (as shown in the figure). You can also move the folder of temporary Internet files to another partition to reduce the disk occupation of the system partition.
4. The file is compressed in 4. new technology file system
Windows XP provides file compression properties for NTFS partition files, which can effectively save disk space.
In NTFS partition, select the file or folder to be compressed, right-click, select Properties from the shortcut menu, and then click Advanced on the General tab of the Properties dialog box. In the Compression or Encryption Attribute column of the New dialog box, select the Compress content to save disk space check box. After "OK", you will find that the disk space occupied by the file is greatly reduced.
5. Clear the Windows XP *** shared folder.
"* * * Enjoy Folder", this folder is useful when we use the workgroup, so we just need to put the files that * * * want to enjoy in this * * enjoy folder without any setting, but in practical application, many people don't need this function. We can disable this function by modifying the registry to save disk space.
Open the registry editor and find the subkey {59031a47-3f72-4a7-89c5-5595fe6b30ee} under "HKEY _ local _ machine \ software \ Microsoft \ Windows \ current version \ explorer \ my computer \ namespace \ delegation folder". It is best to make a backup before deleting it, or write down the value so that it can be restored immediately when needed.
