How to clean the disk how to clean the disk! !

Peeking at disk defragmentation from nine aspects = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =1. What is disk fragmentation? In fact, disk fragmentation should be called file fragmentation, because files are stored in different parts of the whole disk, rather than in continuous clusters of disks.

When the physical memory required by the application program is insufficient, the general operating system will generate a temporary swap file on the hard disk, taking the hard disk space occupied by the file as virtual memory. Virtual memory management programs frequently read and write hard disks, resulting in a large number of fragments, which is the main cause of hard disk fragmentation.

Other settings, such as temporary files or temporary file directories generated when IE browser browses information, will also cause a lot of fragmentation in the system. File fragmentation generally does not cause problems in the system, but too many file fragments will make the system look back and forth when reading files, which will lead to the decline of system performance and even shorten the life of hard disk.

In addition, excessive disk fragmentation may also lead to the loss of storage files. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Second, how do disk fragments come about? In a disk partition, files will be stored in different locations on the disk, rather than in continuous clusters on the disk.

Moreover, because in the process of file operation, Windows system may call virtual memory to synchronize management programs, which will cause each program to read and write hard disk frequently, resulting in disk fragmentation. = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = three. The principle of disk read-write operation After understanding the causes of disk fragmentation, it is necessary for us to understand the situation when the program is running.

Generally, when running a program, the job of the magnetic head of the disk drive is to search the files necessary for the program to run, then read the data, and finally do post-reading processing-transfer the data to the disk cache and memory. Search time is called average seek time in hard disk performance index, and the unit is milliseconds (ms). At present, the average seek time of mainstream hard disks is less than 9.5 ms ..

If the application-related files can be placed in the continuous space of the disk, the time of head search will be greatly reduced. The same is true when reading. The time required for a disk to read the data in the sector below the head is only one-fifth of the time required for moving the head to another position to read the same data.

When reading a disk, the system first checks whether the data is in the cache, and if so, directly reads it; If not, access the disk, that is, read the disk. When the same data needs to be read many times, the cache plays a great role, but it is powerless to read a file for the first time.

Therefore, the search time and reading time greatly affect the efficiency of program execution. Why do you want to defragment the disk? Windows system can't automatically put every file in the most suitable position on the disk according to the principle of minimizing the head search time.

So Microsoft added the "Disk Defragmenter" to Windows, and provided the "TaskMonitor" to track the disk activity during the program startup, so that the "Disk Defragmenter" can work more effectively. "TaskMonitor" automatically runs with Windows startup (of course, you have to select "TaskMonitor" in "Startup").

When an application is loaded, it knows the files searched and called when the program starts by listening to the disk access, locates the required files, and stores the monitoring results in the hidden directory of "C: \ Windows \ Appleg". Most files in this directory have the extension "". Lgx ",where" lg "stands for log file and" X "stands for drive letter, such as" lgd "of program D; The file name of the log file is the file name of the application monitored by TaskMonitor. For example, the WinZip program on E disk is recorded as "Winzip32.lge".

When the user defragments the disk, the program will move the related files of the application to the continuous space on the disk according to the information in the Applog directory. TaskMonitor only searches file information in the process of program loading, and adjusts the optimization order according to the loading frequency of the program, which means that the software that is used the most can get the most attention.

Applog。 The ind file in the applog directory records the number of times the application runs. Users need to start common software several times, be monitored and recorded by TaskMonitor, and then use disk defragmentation to sort it out, so as to really improve the startup speed of the program.

However, if users change common software, such as WinZip, and now use ZipMap, then for a long time, disk defragmentation will first move files related to WinZip to a continuous space instead of ZipMap, unless ZipMap is loaded more times than WinZip. To solve this problem, users can delete the "Winzip32.lgx" file, the record file does not exist, and disk defragmentation will not optimize it.

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Fourth, should the hard disk be cleaned regularly? In fact, there should be no doubt that the hard disk should be sorted regularly. If the hard disk defragmentation will really damage the hard disk, it will be after nearly astronomical defragmentation.

When the hard disk is used for a long time, the storage location of the file will become fragmented-the contents of the file will be scattered in different locations on the hard disk. The existence of these "fragmented files" will reduce the working efficiency of hard disk and increase the possibility of data loss and data damage.

The defragmenter collects these fragments together and stores them as a continuous whole on the hard disk. Windows comes with such a program: DiskDefragmenter, but in the tool software NortonUtilities and Nuts &; There is a better program like this in Bolts.

However, for the moving parts in the hard disk, defragmentation is really a big job. If the hard disk has reached the final stage of its life, defragmentation may indeed be suicide.

But in this case, even if you don't tidy up the debris, it is very difficult.

How to clean the disk

Click the Start button first, and then select the menu item of Programs → Accessories → System Tools → Disk Cleaner to start the Disk Cleaner.

Next, the system will pop up the "Select Drive" dialog box, from which the user can select the disk partition to be cleaned, and then click the "OK" button.

Then the disk cleaner will automatically find all kinds of useless files on the disk partition, such as temporary files downloaded by Inter Explorer, files in the recycle bin, temporary files in the temp folder and so on. , and display all kinds of useless files found in the list window.

Finally, the user can select the file to be deleted from the given junk file list according to his own actual situation, and then click OK, and the disk cleaner will automatically delete it to make room for the disk.

In addition, you can click the "Other Options" tab of Disk Cleaner, and then expand the remaining disk space by deleting some Windows components and uninstalling the installed applications.

How to clean the disk

All kinds of junk files (such as BAK, OLD, TMP files, browser cache files, temporary folders, etc. ) The junk files generated in the process of Windows running will occupy a lot of disk space, and it is more troublesome to clean up than the recycle bin-these junk files are widely distributed in different folders on the disk, and the difference from other files is not obvious, so manual cleaning is very troublesome.

Windows's own disk cleaner can easily solve this problem. Disk Cleaner is a junk file cleaning tool, which can automatically find out all kinds of useless files in the whole disk. It is very simple to solve the problem of disk space with disk cleaner, but even when there is a lot of space left on the disk, we should always run disk cleaner to delete those useless files, which can keep the system simple and greatly improve the system performance.

Finishing method

In Windows, users can select Programs/Accessories/System Tools/Disk Defragmenter from the Start menu, pop up the drive selection window, select the partition to defragment, and then click OK to start defragmentation. However, this method is very time-consuming. For a partition of about 2GB, it usually takes more than 65,438+0 hours, so readers are advised to:

1. When defragmenting the disk, it is best to close all other applications, including the screen saver, and set the size of the virtual memory to a fixed value. Don't read or write to the disk. Once disk defragmentation finds that the files on the disk have changed, it will start defragmentation again.

2. The frequency of defragmentation should be properly controlled, and too frequent defragmentation will also shorten the life of the disk. Disk partitions that usually read and write frequently are sorted once a week.

You can also use other software: for example, Diskeeper can clean up debris. In addition, for example, 360 guards can also carry out partial cleaning to help you clear temporary files.

How to clean up disk garbage?

1. Check "OK" 2 before opening the option of My Computer-Tools-Folder Options-View-Show All Files and Folders. Delete all files in the following folder: x: \ documents and settings \ user name \ cookies \ (keep index files). Documents and Settings\ user name \ local settings \ temp \ x: documents and settings \ user name \ local settings \ temporary files \ x: \ documents and settings \ user name \ Local settings \ history \ x: documents and settings \ user name \ recent \ x: \ Windows \ temp \ x: \ Windows \ ServicePackFiles (backup files after upgrading sp 1 or sp2) X: Compressed files under X:driver cache If you upgrade your system with windoes updade, please delete the following files: X: \ Windows \ with $ u.

Hidden file 4 at the beginning. Then defragment the disk. During the defragmentation process, please exit all running programs. 5. After defragmentation, open Start-Programs-Accessories-System Tools-System Restore-Create a restore point (it is best to use the current date as the name of the restore point). 6. Turn on my computer-right click on the system disk-Properties-Disk cleaning-Delete the system backup file: Start → Run → sfc.exe/Purge Cache nearly 3xxM.

(The function of this command is to clear the cache of Windows File Protection file immediately and release the space occupied by it. 8. Delete the dll file under \windows\system32\dllcache (minus 200——300mb), which is a spare dll file. As long as you copy the installation file, you can do it completely. 9.XP will automatically back up the hardware driver, but it is generally unlikely to change the hardware after the hardware driver is installed correctly, so you can also consider deleting this backup. The file is located in the \windows\driver cache\i386 directory and named driver.cab You can delete it directly, usually the file is 74M.

10, delete unused input methods: For many netizens, not all input methods included in the Windows XPt system are suitable for their own use, such as IMJP8_ 1 Japanese input method and IMKR6_ 1 Korean input method. We can delete them if it is not necessary. Input method is located in \windows\ime\ folder, occupying 88M space.

1 1. After upgrading, I found that windows\ has many directories similar to $ ntuninstallq311889 $. Kill them all, 1x-3xM 12. Besides, it's not good for me to put things in the \windows\help directory.

. Kill them all! 13. Turn off system restore: The system restore function takes 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 option, and select the Turn off System Restore on all drives check box to turn off System Restore.

You can also set to restore only 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.

14, the hibernation function will take 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. 15, uninstall unused components: XP installs some system components for the operating system by default, and a large part of these components are impossible for you to use. You can uninstall them in Add/Remove Windows Components.

However, some components in XP are hidden by default and cannot be found in Add/Remove Windows Components. At this time, you can open the file \windows\inf\sysoc.inf with Notepad, and replace all the "hidden" characters in the file with spaces with the find/replace function. In this way, the hidden properties of all components are removed. After saving, run the Add-Remove program, and you will see many options that you didn't see before. Delete those components you don't need (remember to save them as sysoc.inf instead of the default sysoc.txt), such as Internat messenger service, fax service, Windows messenger, code table, etc. , can release nearly 50MB of space.

16. Clear the temporary files of the system: 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 (Y: the partition where the system is located). Files in both locations can be deleted directly.

17. Clear temporary files between computers: deleting a large number of temporary files between computers regularly will save a lot of hard disk space. Open IE browser, select Inter option in the Tools menu, select the General tab in the pop-up dialog box, click Delete File in the Inter Temporary File column, select the Delete All Offline Content checkbox in the pop-up Delete File dialog box, and click OK.

18. Clear the pre-read files: Although the pre-read setting of Windows XP can improve the system speed, after a period of use, the number of files in the pre-read folder will become quite large, resulting in a long system search time. Moreover, some applications will produce dead-chain files, which will increase the search burden of the system.

So these pre-read files should be deleted regularly. The expected file is stored in the Windows XP system folder.

How to clean the disk

1. Clean the disk before sorting.

In the My Computer window-right-click the drive to defragment-Properties-General-click Disk Cleanup-open the Disk Cleanup dialog box-check the files to be deleted-OK-Yes-the system will automatically clean up the selected files.

2. Scan the disk before finishing.

In the "My Computer" window-right-click the drive to defragment the disk-Properties-Tools-Start Checking-Check Disk Options-Start-Check and confirm to exit.

3. Close all running programs, especially real-time virus monitoring programs and screensavers.

4. Disk defragmentation.

My computer-right-click the drive to be defragmented-Properties-Tools-Select the disk to be defragmented to open the Disk Defragmenter window-Analysis-Defragmenter-the system will start defragmentation and will inform you when it is finished.

Note: Do not read or write any data when sorting. Reading or writing at this time may cause the computer to crash. If this does not clean the selected disk, it must be cleaned in safe mode.

5. Use the disk defragmentation tool that comes with the system. If you can't defragment, you can use Optimizer and other software to defragment.

The computer disk is full. How to clean it?

1. Click Program Accessories in the Start menu, click System Tools, then click Clean Disk, select Drive C, and then confirm by selecting all ports. It takes a long time to click "Disk Defragmenter" in System Tools. Please be patient. Some programs have been deleted, but they have not been completely deleted, and the installation information remains in the computer registry. If this useless information is not deleted in time, the registry will become bigger and bigger after a long time, which will affect the working performance of the system. You can delete it completely in the following ways.

2. After repeated installation and uninstallation, the system keeps many useless DLL files, which should be deleted. Click the Start menu, click Run, type "regedit" in the text box, open the Registry Editor window, and then open the branch of HKEY _ Local _ Machine \ Software \ Microsoft \ Windows \ Current Version \ Shared dll. On the right side of the dialog box, there is a number in parentheses after the key value data. If the number is 0, it means that this DLL file has become garbage, so delete it.

3. When uninstalling unnecessary programs, you should select "Add/Remove Programs" in the control panel to confirm the deletion, which is the method of complete deletion. Deleting in the disk partition is not effective, and sometimes some programs cannot be deleted. Even if Add/Remove Programs in Control Panel is uninstalled, some programs still keep the names of these programs in the registry, thus becoming junk. Use the above method to open the registry editor window, and then open HKEY _ Local _ Machine \ Software \ Microsoft \ Windows \ Current Version \ Uninstall Branch. Each folder under the Uninstall primary key corresponds to an application. When you open the folder, you can see the contents of the uninstaller, including the program names DisplayName and UninstallString. After finding the name of the program you deleted, right-click its parent folder and select Delete.

4. Some programs that can be run directly in Windows without uninstalling the program or installing (copying to the computer), such as many small games, the registry records the running parameters of the program. If you delete such a program, you still need to delete this useless information in the registry. Open HKEY current user software branch. After finding the folder of the corresponding program from each subitem, delete it. You can also click Edit | Find to find the sub-items or key items containing these software information one by one and clean them up thoroughly.

The specific operation method is as follows: 1. Open the resource manager to see if there is not enough space on drive C. If there is not enough space, it will be displayed in red.

If red is displayed, you need to clean the disk. 2. Right-click drive C, and then select bottom properties in the pop-up menu to enter the property page of drive C. ..

3. There is a button to clean up the disk in the property page, that is, clean up the junk files on this disk, and click this button with the mouse. 4. Then the program will start searching for junk files and calculate how much hard disk space can be released. If you have too many junk files, it will take a long time.

5. After the search is completed, a list will appear, which contains some useless files. There will be an option in front of you to delete some files according to your choice, and then click OK. 6. At this time, you will be prompted to confirm whether to delete these files. If you are sure, click Delete File.

7. As shown in the figure, the program is cleaning the file you selected. After cleaning up, your C drive will have a lot more space. 8. If your disk space is too small, you can choose a compressed drive in the property page to save disk space, which can save space to some extent.
