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. Ime 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.

CHSIME: simplified Chinese input method;

CHTIME: traditional Chinese input method;

IMEJP: Japanese input method;

IMEJP98: Japanese 98 input method;

IMJP8_ 1: Microsoft IME standard 2002 version 8.1;

IMKR6_ 1: Korean (Ime2002) version 6. 1 input method;

SHARE: folder of East Asian languages. Font Folder This is the font folder, which is used to store font files that will be used by the system. Fonts newly installed by users themselves will also be stored in this folder. Among them, there are many English font types, while the simplified Chinese font file only includes four types: imitation Song, bold, italic, Song Song and New Song, that is, GB23 12 in computer coding. You can delete some English fonts that are not commonly used. The Installer folder is used to store MSI files or temporary files needed for program installation. MSI file is the installation package of Windows system. Right-click the file and you can choose to install or uninstall the program in the right-click menu. Some programs must use MSI files when uninstalling, so deleting files in this folder is not recommended. 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 installing, so it is strongly opposed to deleting files under this folder or under this folder. Because there are many files in this folder and under this folder, we only list some representative folders ① CatRoot: the directory used to store computer startup test information, including hardware and software information detected when the computer starts.

② Com: 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 backed-up system file to 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 IME folders.

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.

Pet-name ruby pool: used to store system print files. Include printing color, printing pre-storage, etc.
