Deep understanding of the VISTA/XP operating system: C Packing Directory folder and file parsing

Windows XP Pro SP2 single system, the C-packing directory has 14 files and folders (which hides 11). XP and Vista dual systems run when there are 20. For these files and folders, whether the number, or function, should be very understanding, today we have to do these analysis, hope to help you.

(i) File and folder resolution on a single system

(1) RECYCLER

Recycle Bin

(2) Documents and SettingS

folder where user configuration information is stored

(3) Program FileS

Application Folder

(4) System Volume Information

The storage system restores the backup information folder.

(5) WindowS

Operating system Folder

(6) Bootfont.bin

Operating system localization boot menu file

(7) Ntdetect.com

A system-level file that initializes a hardware device and then passes the hardware information to the next boot step, which eventually completes the operating system's startup.

(8) NTLDR

Very important system files. It gives the CPU control to the operating system after it is started. The operating system cannot be entered once it is lost.

(9) AUTOEXEC. BAT

Dos in the startup will automatically run this file, usually in the load every required program, such as: path (set path), Smartdrv (disk acceleration), mouse (mouse boot), MSCDEX (optical drive connection), Doskey (keyboard management), set (set environment variables).

(10) CONFIG. SYS

This file is used for loading programs at system startup and is important in DOS. But under the Windows operating system, this file is not generally used.

(11) Io. SYS

Provides the standard hardware's input/output interface and DOS interrupt invocation, the function is overall enhanced, it basically controls the entire boot process, is the Windows DOS Real mode core document. But it needs to be based on the Msdos.sys settings to achieve the normal boot process.

(12) MSDOS. SYS

As the core file in the system disk, it is necessary to start the system. In the DOS operating system era, the primary responsibility is to build, delete, and read and write disk file management, as well as memory management, disk and other system resources management.

(boot.ini)

If you have more than one operating system installed in your computer, a startup menu will appear after the computer has a self-test, which lists all the operating systems installed on this computer, and the user uses the "↑" "↓" button to choose which system to enter. It all stems from this file, which Windows XP relies primarily on boot. INI file to determine which operating system categories the computer displays during the reboot (boot) process.

(Pagefile.sys)

is virtual memory under Windows, which is essentially similar to physical memory, but it exists as a "backup force" of physical memory. That is, it works only when the physical memory is not in use. We all know that although the hard disk is not as good as memory at run speed, memory cannot be compared with the hard disk in the capacity. When you run a program that requires a lot of data, consumes a lot of memory, the memory is "stuffed" and the data that is temporarily unused is placed on the hard disk, which occupies the space of virtual memory.
