WinXP System C Disk important documents to avoid accidental injury

First of all, let's take a look at a newly installed XP system C-Disk chart:

Just installed the C-disk file is this off, of course, if you do not choose to display hidden files and system files in Folder Options, you can only see documents and setting, program Files, Windows three folders.

Below we will explain the use of the above files, of course, as the system files are extremely important, so you can not delete them.

　　1, Documents and setting folder is what?

The C:/document and setting directory is a directory where the account settings are saved, starting with Win2000. Starting from Win2000, the system runs on account basis: The system's own services, network services, users and so on are the identity of the account appears,

The settings for all accounts are stored in folders with different account names under the/document and setting directories. This is still true in XP, but the/document and setting directories are not used in the Win7, but are changed to the user directory.

　　2, Program Files folder:

Program files are Programs folder, that is, the Windows operating system, and of course, other operating systems are installed by default to the various software directory, located in the C disk partition ("C:/Program Files", "%ProgramFiles%"). However, you can customize to a different partition according to the needs of the user.

　　3. Windows folder:

Windows folders can be said to be the most important Windows system folder, this folder for the win system, the main system file storage directory, so the computer is not very familiar with friends generally do not need to change any of the files inside.

　　4, $RECYCLE. Bin folder: This folder is equal to the system's retract station, which is available on every local disk in the system and cannot be deleted, and files that are normally deleted will be in the folder without emptying.

　　5, Recycle folder: the same is the win system of the recovery station, in the system of each local disk has, the normal removal of files in the absence of the empty case will be in the folder.

　　6, System Volume information is what folder : This folder for the System Restore point directory.

　　7, Autoexec.bat is what file:

Autoexec.bat is a previously dos,win95, WIN98, System-initiated call file that is used to set up batch execution commands.

XP Autoexec.bat can be edited with the edit command, but you must know how to write in it.

　　8, Boot.ini is what file:

Windows XP relies primarily on Boot.ini system files to determine which operating system categories the computer displays during the reboot (boot) process. The Boot.ini is set to the implied and System file properties by default and is identified as read-only.

Windows NT, Windows 2000, Windows XP, and Windows Server 2003 rely primarily on Boot.ini files to determine which operating system categories the computer displays during the boot process.

When we have multiple systems installed on our computers (such as Windows 98 and Windows XP), a System boot menu appears each time you start your computer, where you select the system you want to enter and then enter. This bootstrapper, named Boot.ini, is automatically installed when Windows XP is installed, using which we can easily boot multiple systems on the computer, and through the boot file, set up a personalized boot menu.

　　A typical Boot.ini format:

[boot loader]

Timeout=5

Default=multi (0) disk (0) rdisk (0) partition (1)/windows

[Operating Systems]

multi (0) disk (0) rdisk (0) partition (1)/windows= "Microsoft WINDOWS XP Professional"/noexecute=optin/fastdetect

　　9, Bootfont.bin file : Boot menu effect spironolactone file, missing this file will cause the boot menu can not display Chinese.

　　10, Config.sys file:

CONFIG. SYS is a text file command contained in a DOS (disk operating system, diskette operating system) that tells the operating system how the computer is initialized. In most cases, CONFIG. SYS commands the development of memory device drivers and programs to control hardware devices, to open or to system features, and to restrict system resources. CONFIG. SYS loads before the Autoexec.bat (automatic batch process) file executes. Because Config.sys is a text file, it can be edited using a text editor.

　　11, Io.sys is what file:

Io. SYS is an important startup file in the Win9x mode, which mainly controls the important conversion between the machine and the operator in the start-up, and is the hub of the Win9x system startup. Io. SYS is located under c:/, and Msdos.sys COMMAND. COM together form the core of Win9x, typically system, read-only, hidden properties. Among them, the Msdos.sys plays a role in Io.sys configuration. Win 9X Io.sys by the original DOS system files Io.sys, MSDOS. SYS merged to provide the standard hardware input/output interface and DOS interrupt calls, full-featured enhancements, it basically controls the win 9X all START process, is the Windows DOS Real mode of the core file. But it needs to be based on the Msdos.sys settings to achieve the normal boot process.

　　12, Msdos.sys file:

MSDOS. SYS is one of the three core files for DOS, and the other two are Command.com, IO. SYS

In Win 9X, MSDOS. SYS becomes a plain text system configuration file that controls how the win is started. You can remove its special properties (read-only, hide, System) in DOS mode, and configure it on demand.

　　13, Ntdetect. What file is COM : NT system boot file, executable file. The file system is missing and will not start.

　　14, NTLDR file:
