WINDOWS will also automatically save some temporary files during use. If System Restore is turned on, it will also automatically save some restore points, so WINDOWS folders will be added automatically.
The following are the functions of files in the WINDOWS folder:
In a real Windows folder, let's start with the folder. These folders are very important and are the necessary guarantee for the normal operation of the system. Explain the order.
Cursor folder
This is the mouse pointer folder, which is used to store the mouse pointer instead of the system default. Some programs that beautify the system desktop will also store the mouse pointer in this folder when beautifying the mouse. You can delete the mouse pointer in the folder without affecting the default mouse pointer of Windows system.
Debugging folder
This is the system debugging folder, which is used to store the log files of the debugging module when the system is running, so that the administrator can find the problems existing in the computer according to these log files. The User Mode folder stores the debug log file of the current user.
Downloaded program file folder
This is the download folder, which is used to store files that extend the functions of IE browser. For example, controls that allow IE to play FLASH animations, Java virtual machine controls, and so on.
Help folder
This is the help folder, which is used to store the help files attached to the system and some applications. Of course, these files can be deleted (but the Tours folder cannot be completely deleted). You can click Help and Support from Start to start the help system, which will actually call some files in this folder.
Input method folder
This is the input method folder, which is used to store the input method files installed by default. Windows operating system has embedded input methods in East Asian countries, such as Japanese and Korean. Theoretically, it is possible to delete some input methods in other languages that are not used, but this is not recommended, because it may lead to the instability of the input method system and seriously affect the normal use of simplified Chinese input methods.
PCHealth folder
It is used to store files that coordinate, configure and manage the normal operation of the computer. For example, the commonly used msconfig system configuration utility is located under \ HelpCtr\Binaries, and the offline browsing cache is located under the OfflineCache file. The files here are very important to the operating system and are not recommended to be deleted.
Repair folder
This is the system repair folder, which is used to store configuration files when repairing the system. When the system can't enter the desktop, we will first choose to repair the system if we have to. This file is the basic configuration file of the system.
Resource folder
This is the system resource folder, which is used to store the system SHELL resource files, which is the theme we see on the desktop. You can delete some useless theme files.
Addins folder
This is the additional folder of the system, which is used to store files of additional functions of the system.
AppPatch folder
This is the application patch backup folder, which is used to store application patch files.
Configuration folder
This is the system configuration folder, which is used to store some temporary configuration files of the system.
Connect wizard folder
As can be seen from the name, this is the connection wizard folder, which is used to store the related files of the Internet connection wizard.
Secure folder
This is the system security folder, which is used to store important data files of the system.
Srchasst folder
This is the search assistant folder, which is used to store system search assistant files, similar to the msagent folder.
System folder
This is the system folder for storing system virtual device files. These files logically create a complete set of virtual devices for the system at startup, especially when hardware drivers are not installed.
Driver cache folder
This is the driver cache folder, which is used to store driver files for hardware known to the system. After the Windows operating system is installed by default, there will be an "i386" folder with a file named "driver.cab", which is the driver library file of the known hardware that comes with the Windows operating system.
Many articles on the network say that this driver library file can be deleted to save space, but after deletion, there will be many inconveniences, such as using USB devices and installing drivers. Therefore, it is recommended not to delete this file.
System32 folder
This is a 32-bit system folder for storing important system files. At the same time, some applications will copy their corresponding supporting files to this folder when they are installed, so we strongly oppose deleting the files under this folder or under this folder. Because there are many files in this folder and under this folder, we can't discuss them one by one. Only some representative folders and files are listed.
1.CatRoot: a directory for storing computer startup test information, including hardware and software information detected when the computer starts.
2. It is used to store component service files. Running "comexp.msc" will open the component service console.
3.DllCache: used to store system cache files. When the original system file is replaced, the file protection mechanism will copy the backup system file in this folder to overwrite the non-system file. You can use the "SFC \SCANNOW" command format to scan system files, and then you can delete all files under it.
4. Driver: used to store hardware driver files. If the file is deleted, the hardware will lose its driver and become invalid.
5.IME: used to store system input method files, similar to the IME folder on the screen.
6.oobe: used to store the activation information of the system.
7.Restore: used to store system restore files. Double-click to run the rstrui.exe file, and the system recovery function will be called.
8.Setup: used to store system installation files.
9.spool: used to store system print files. Include printing color, printing pre-storage, etc.
10.wbem: used to store WMI test programs and view and change common information model classes, instances and methods. This is an important system file and cannot be deleted.
