c disk full how to do, c disk space is insufficient, these common computer memory problems have been encountered by netizens The problem, some netizens recommend downloading some optimization tools that are easy to damage the normal files of the system due to the optimization transition. There is also a C drive is the local default system boot hard drive, C drive main folder has Documents and Settings folder, Windows folder, Program Files folder, the program installation and installation path is the default C drive path, so a large number of systems This is also the most normal thing about garbage. The following is a detailed explanation of which files can be deleted in the c drive and does not affect the computer system.

First, let's take a look at the method recommended by netizens to deal with the lack of c-disk space:
User recommendation method:

Use my method to clean up and see, maybe you can add a lot of space for you:

1. Display all the hidden files of the C drive. It is better to display the "hidden protected operating system files" so that you can see what files occupy the space.

2, it is better to set the "virtual memory" to another disk, "virtual memory" can add at least a lot of space here; the system's own restore function is also canceled, also Cancellation function is canceled, so you can add a lot of space after setting.

3, it is best to clean the disk regularly, so that you can remove those temporary and cache files, or it may be that some files of your anti-virus software will take up a lot of space. Go to open each folder and check it out.

Let's take a look at the "C disk full how to do" course: What files in the c drive can be deleted

1. Open "My Computer" - "Tools "-"Folder Options" - "View" - check the "Show all files and folders" option - "OK" 2. Delete the contents of the following folder: x:\\Documents and Settings\\username\\Cookies All files under \\ (retain index file) x:\\Documents and Settings\\username\\Local Settings\\Temp\\ all files (user temporary files) x:\\Documents and Settings\\username\\LocalSettings\\TemporaryInternet Files\\ All files (page files) x:\\Documents and Settings\\username\\Local Settings\\History\\ under all files (history) x:\\Documents and Settings\\username\\Recent\\ all files (recently browsed files) Shortcuts) All files under x:\\WINDOWS\\Temp\\ (temporary files) x:\\WINDOWS\\ServicePackFiles (upload files after upgrading sp1 or sp2) compressed files under x:\\WINDOWS\\Driver Cache\\i386 (driver Program backup file) x:\\WINDOWS\\SoftwareDist All files under ribution\\download 3. If you have upgraded the system by windoes updade, delete the following files: hidden files starting with $u... under x:\\windows\\ 4. Then defragment the disk, finishing process Please quit all running programs. 5. Open the "Start" - "Programs" - "Accessories" - "System Tools" - "System Restore" - "Create a Restore Point" (preferably with the current date) The name of the restore point) 6. Open "My Computer" - right click on the system disk - "Properties" - "Disk Cleanup" - "Other Options" - click "Clean" in the System Restore column - select "Yes" - Ok 7, after all kinds of software and hardware are installed properly, in fact, when XP needs to update the file, it is very rare. Delete the system backup file: Start → Run → sfc.exe /purgecache nearly 3xxM. (The function of this command is to immediately clear the "Windows File Protection" file cache and release the space it occupies.) 8. Delete the dll file under \\windows\\system32\\dllcache (minus 200-300mb), this is the backup. The dll file, as long as you have copied the installation file, you can do so. 9, XP will automatically back up the hardware driver, but after the hardware driver is installed correctly, it is generally not possible to change the hardware, so you can also consider deleting this backup, the file is located in the \\windows\\driver cache\\i386 directory. The name is driver.cab, you can delete it directly, usually this file is 74M. 10, delete the input method is not used: For many users, the input method of Windows XPt system is not all suitable for their own use, such as IMJP8_1 Japanese input method, IMKR6_1 Korean input method, if not used, We can remove it. The input method is located in the \\windows\\ime\\ folder, which takes up 88M of space.

11. After the upgrade is completed, I found that windows\\ has a lot of directories like $NtUninstallQ311889$, all of them are killed, 1x-3xM12, in addition, keeping the contents of \\windows\\help directory is a kind for me. Hurt, huh, huh. . . Do it all! 13. Turn off System Restore: The system restore function takes a long time and takes up a lot of hard disk space. Therefore, it is necessary to manually set it to reduce the amount of hard disk usage. Open the System Properties dialog, select the System Restore option, and select the Turn off system restore on all drives check box to turn off System Restore. You can also set restores only on the disk or partition where the system is located. First select the partition where the system is located, click the "Configure" button, in the pop-up dialog box, cancel the "Close the system restore of this drive" option, and set the amount of disk space for system restore. 14, the hibernation function will take up a lot of hard disk space, if you use less, you can close it, the way to close is: open the "Control Panel", double-click "Power Options", in the pop-up "Power Options Properties" dialog box Select the "Hibernate" tab and uncheck the "Enable hibernation" checkbox. 15. Uninstalling Unused Components: XP installs some system components to the operating system by default. A large part of these components are not available to you. You can uninstall them in "Add/Remove Windows Components". But some of the components XP are hidden by default. They can't be found in "Add/Remove Windows Components". You can do this by opening the file \\windows\\inf\\sysoc.inf with Notepad and using Find/Replace. The function replaces all the "hide" characters in the file with null. In this way, the hidden attributes of all components are removed. After saving and exiting the "Add-Remove Programs", you will see a lot of options that you could not see, and delete those components that you can't use. (Remember to save as sysoc.inf when saving, instead of the default sysoc.txt), such as Internat messenger service, fax service, Windows messenger, code table, etc., about vacating nearly 50MB of space. 16. Clear system temporary files: Temporary files of the system are generally stored in two locations: the Temp folder in a Windows installation directory; the other is x:\\Documents and Settings\\"Username"\\Local Settings\\Temp folder (Y: is the partition where the system is located). Files in both locations can be deleted directly. 17. Clear Temporary Internet Files: Regularly delete a large number of temporary Internet files generated during Internet access, which will save a lot of hard disk space. Open Internet Explorer, select "Internet Options" from the "Tools" menu, select the "General" tab in the pop-up dialog box, click the "Delete Files" button in the "Temporary Internet Files" column, and pop up " In the Delete File dialog box, select the "Delete all offline content" check box and click the "OK" button. 18, clear pre-read files: Windows XP pre-read settings can improve the system speed, but after a period of use, the number of files in the pre-read folder will become quite large, resulting in longer system search time. Moreover, some applications generate dead link files, which further burdens the system search. Therefore, these read-ahead files should be deleted periodically. It is expected that the files will be stored in the Prefetch folder of the Windows XP system folder, and all files under this folder can be deleted. 19, compressed NTFS drive, file or folder: If your hard disk is using NTFS file system, the space is really tight, you can also consider enabling NTFS compression. Right-click the drive you want to compress - "Properties" - "General" - "Compress Disk to save disk space", then click "OK", select the desired option in "Confirm Property Changes". This saves about 20% of your hard drive space. When compressing the C drive, it is best to compress it in safe mode, which is better. 20. Close Dr. Watson: To close Dr. Watson, open the Registry Editor, find the "HKEY_LOCAL_MACHINE\\ SOFTWARE\\Microsoft\\WindowsNT\\CurrentVersion\\AeDebug" branch, double-click the Auto key name under it, and set its value The data is changed to 0, and finally press F5 to refresh the settings, thus canceling its operation. Also enter "drwtsn32" command in "Start" -> "Run", or "Start" -> "Program" -> "Accessories" -> "System Tools" -> "System Information" -> "Tools"-> "Dr Watson", call the Dr. Watson in the system, only the "dump all thread context" option, otherwise the hard disk will read for a long time and take up a lot of space. If this is the case before, please find the user.dmp file, which can save tens of megabytes of space after deletion. 21, close the remote desktop: "My Computer" -> "Properties" -> "Remote", "Remote Desktop" in the "Allow users to remotely connect to this computer" tick off. 22, cancel XP support for ZIP: Windows XP opens the support for zip files by default, which takes up certain system resources, you can choose "Start → Run", in the "Run" dialog box, type "regsvr32 /u zipfldr .dll", press Enter to cancel XP's support for ZIP decompression, saving system resources. 23. Close the error report: When the application error occurs, a window for sending the error report will pop up. In fact, such an error report has almost no meaning to the average user. It is a wise choice to close it. In the "System Properties" dialog box, select the "Advanced" tab, click the "Error Report" button, in the "Error Reporting" dialog box that pops up, select the "Disable Error Reporting" option, and finally click "OK" can. In addition, we can also close the error report from Group Policy: type "gpedit.msc" from "Run", run "Group Policy Editor", expand "Computer Configuration → Administrative Templates → System → Error Reporting Function", double click the right setting "Report Error" in the column, you can disable "Report Error" by selecting the "Disabled" radio button in the pop-up "Properties" dialog box. 24, turn off unused devices: Windows XP always installs drivers and manages all the devices on the computer as much as possible. This not only slows down the system startup, but also causes a large amount of system resources. In this case, you can disable the less commonly used devices such as PCMCIA card, modem, infrared device, printer port (LPT1) or serial port (COM1) in the device manager by double-clicking the device to be deactivated. Select "Do not use this device (disabled)" in the "General" tab of its properties dialog. The settings are valid when the settings are restarted, and are enabled from the device manager when they are needed. 25, regularly clean up the system restore point: open the disk cleanup, select other options -> clean up the system restore point, click clean. 26, uninstall the unwanted programs, this does not need me to say more 27, other optimization: a install the application software on other hard drives (do not install in the system disk, this is also good for reinstalling the system); b will be "my The document "folders are all transferred to other partitions: right click on the "My Documents" icon on the desktop, select "Properties" -> "Move"; c Move the IE temporary folder to another partition: Open IE Browser, select "Tools" -> "internet options" -> "General" -> "Settings" -> "Move Folders"; d Transfer virtual memory to other hard disks; e put pagefile.sys The files all point to one place: Control Panel → System → Performance - Advanced → Virtual Memory → Change, note that the "Settings" will take effect; f Right click on the "My Computer" icon on the desktop, select "Properties" - >"Advanced - Performance Settings" -> "Advanced - Virtual Memory", adjusted to 330-720. And the time to clean up the warm reminder: on the above for the detailed explanation of the c disk is full of space problems, I believe that everyone has found a solution to the problem, I hope you can share this good method to your friends, you can also write an article Write down your comments or suggestions to us on the message board below, thank you for reading!
