C:\WINDOWS\CSC目錄下的文件是？？

OS: Microsoft Windows XP Pro
在 C:\Windows\CSC
裡面的檔案可以刪嗎?
裡面就有大概 4 GB 多的檔案
1. 這些是不是離線資料夾用的檔案啊?
2. 刪了會不會影響?

C:\WINDOWS\CSC目錄下的文件是"启用脱机文件"后所需要的文件，

当禁用脱机文件后系统在启动时就不会去读取此目录。
禁用脱机文件的方法是在"文件夹选项"的"脱机文件"标签中设置。
可以删

Sync v2.0

Introduction

UNIX provides a standard utility called Sync, which can be used to direct the operating system to flush all file system data to disk in order to insure that it is stable and won't be lost in case of a system failure. Otherwise, any modified data present in the cache would be lost. Here is an equivalent that I wrote, called Sync, that works on all versions of Windows. Use it whenever you want to know that modified file data is safely stored on your hard drives. Unfortunately, Sync requires administrative privileges to run. This version also lets you flush removable drives such as ZIP drives.

Using Sync

Usage: sync [-r] [-e] [drive letter list]

-r	Flush removable drives.
-e	Ejects removable drives.

Specifying specific drives (e.g. "c e") will result in Sync only flushing those drives.
