磁盘碎片整理程序发现不存在的文件 [英] Disk defragmenter finds non existent files

问题描述

当我在Windows XP上运行磁盘碎片整理程序时，它正在移动不存在的文件。我的意思是我搜索硬盘驱动器（包括搜索hiddens文件等），我找不到文件。有谁知道这会怎么样？

When I run disk defragmenter on Windows XP it's moving files that do not exist. I mean I search the hard drive (including search for hiddens files, etc.) and I can't find the files. Does anyone know how this can happen?

推荐答案

这是可以解释的。这些文件实际上可能存在，但您从未将它们视为文件系统用户。



在任何文件系统中，磁盘上都有作为内部系统的区域存储需要支持文件系统本身的功能。对于一个简单的例子，在FAT文件系统中这样的存储是FAT，文件分配表。



NTFS的设计是不同的。 在NTFS中，从技术上讲，这些区域也是文件。它们被称为系统文件，但在文件系统意义上，系统不是OS的意义上。特别是，它具有主文件表（MFT）和MFT记录。每个MFT记录都是一个真实的文件，其文件名。您可以在下面看到他们的名字：

从文件系统用户的角度来看，它们根本不是文件，但从技术上讲，它们是。他们通常参与碎片整理，这就是碎片整理程序可以向你展示的原因。

This is explainable. The files may actually exist, but you never see them as a file system user.

In any file systems, there are areas on disk which serve as internal "system" storage needed to support functionality of the file system itself. For a trivial example, in FAT file system such storage is FAT, "File Allocation Table".

The design of NTFS is different. In NTFS, technically, such areas are also files. They are called "system files", but "system" not in the sense of OS, in the sense of file system. In particular, it has Master File Table (MFT) and MFT records. And each of MFT records is a real file, with its file name. You can see their names below:
http://www.ntfs.com/ntfs-system-files.htm[^],
http://www.ntfs.com/ntfs.htm#basics[^].

From the standpoint of the file system user, they are not file at all, but technically, they are. And they are generally involved in the defragmentation, that's why they the defragmenter can show them to you.

你是什么意思？碎片整理不移动文件，它只移动属于文件的数据，压缩文件。



祝你好运！

What files do you mean? Defrag doesn't move files, it only moves data that belongs to the files, compacting the files.

Good luck!

实际上，我弄清楚它是什么。它们是System Volume Information文件夹中的文件，该文件夹存储了恢复信息

Actually, I figured out what it was. They were files in the "System Volume Information" folder, which stores restore information
