WinXP system C disk important documents to avoid accidental injury

A lot of rookies will faint about what is the system disk. In fact, the C disk in the XP system is very important. The XP system is also installed in the C disk, so the system disk of the XP system is the C disk. In order to avoid system file loss, let's take a look at the C drive of the XP system.

Friends install the system in the computer store, the technical staff will generally 叮嘱 C disk files do not delete, install the software as much as possible installed in the D drive. After we have read the following tutorials, you will understand a little bit and it is an essential part of learning a computer.

First, let's take a look at a newly installed XP system C disk structure:

The newly installed C disk file is the same, of course, if you are not If you choose to show hidden files and system files in the folder options, you can only see the Documents and setting, Program Files, and Windows folders.

Let's talk about the purpose of the above files, of course, as system files are extremely important, so you can not delete them.

1. What is the Documents and setting folder?

The C:\\document and setting directory is available from Win2000 and is the directory where the account settings are saved. Starting with Win2000, the system runs on an account basis: the system's own services, network services, users, etc. all appear as accounts,

All account settings are saved in the \\document and setting directory. In the folder of the account name. This method is still the case in XP, but in the Win7, the \\document and setting directory is not used, but changed to the User directory.

2, Program Files folder:

Program Files is the program folder, that is to say the Windows operating system, of course, including other operating system software installed by default, located in C Disk partition (“C:\\Program Files”,“%ProgramFiles%”). But it can also be customized to other partitions according to the needs of users.

3, Windows folder:

Windows folder can be said to be the most important folder of the windows system, this folder is the main system file storage directory of the win system, so the computer is not A friend who knows very well does not need to change any of the files inside.

4, $RECYCLE.BIN folder: This folder is equal to the system's reclaim station, in the local disk of the system, can not be deleted, the normal deleted file is not empty Will be in this folder.

5, RECYCLE folder: The same is the recovery station of the win system, in each local disk of the system, the normally deleted files will be in this folder without emptying.

6, system volume information What is the folder: This folder is the system restore point storage directory.

7, Autoexec.bat What is the file:

autoexec.bat is the previous DOS, WIN95, WIN98 system startup file call, used to set the batch execution command.

XP autoexec.bat can be edited with the EDIT command, but you must know how to write it inside.

8. What is the file Boot.ini:

Windows XP relies heavily on the Boot.ini system file to determine which operating system categories are available for display during the reboot (boot) process. Boot.ini is set to implicit and system file attributes by default and is identified as a read-only file.

Windows NT, Windows 2000, Windows XP, and Windows Server 2003 rely primarily on the Boot.ini file to determine which operating system categories are available for display during the boot process.

When we installed multiple systems (such as Windows 98 and Windows XP) on the computer, a system boot menu will appear each time you start the computer. Here you can select the system you want to enter and press Enter. This bootloader is called Boot.ini. When Windows 2000 (XP) is installed, the program is automatically installed. With it, we can easily boot multiple systems on the computer, and also set a personalized boot menu through the boot file.

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: The security file that launches the boot menu. If this file is missing, the boot menu will not display Chinese.

10, Config.sys file:

CONFIG.SYS is a text file command contained in DOS (Disk Operating System), which tells the operating system how to initialize the computer. In most cases, the CONFIG.SYS command develops memory device drivers and programs to control hardware devices; enable or characterize system features; and limit system resources. CONFIG.SYS is loaded before the autoexec.bat (automatic batch program) file is executed. Since CONFIG.SYS is a text file, it can be edited using a text editor.

11. What is IO.sys file:

IO.SYS is an important startup file in WIN9X mode. The main control is the important conversion between the machine and the operator. It is WIN9X. The hub of the system startup. IO.SYS is located under C:\\, and together with MSDOS.SYS COMMAND.COM constitutes the startup core of WIN9X, usually system, read-only, and hidden attributes. MSDOS.SYS configures IO.SYS. Win 9X's IO.SYS is a combination of the original DOS system files IO.SYS and MSDOS.SYS. It provides standard hardware input/output interface and DOS interrupt call. The function is comprehensively enhanced. It basically controls all the Win 9X. The boot process is the core file of Windows DOS real mode. However, it needs to be set according to MSDOS.SYS to achieve the normal boot process.

12, msdos.sys file:

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

In Win 9X, MSDOS.SYS becomes a plain text system configuration file that controls the startup mode of Win. You can undo its special properties (read-only, hidden, system) in DOS mode and configure it as needed.

13, what is ntdetect.COM file: is the NT system boot file, executable file. Missing this file system will not start.

14, NTLDR file:

NTLDR full name is NT Loader, is the system loader

NTLDR file is Windows NT/windows 2000/windows XP/windows server 2003 boot File, when the file is lost, the system will prompt "NTLDR is missing." . ”

15. What is Pageflie.sys: The page file is the virtual memory. The file is automatically generated, and the size can be customized or automatically adjusted.

In the C drive of the WinXP system, documents such as Documents and setting can often be seen. Now they finally understand their role. Of course, deletion is dangerous, and novices need to be cautious. As a rookie, don't just move the files on the system disk, let alone delete it.
