COMPACT /U 命令无法解压 25GB 大文件

我有一个 25GB 的文件，由于创建时其所在目录已标记为压缩，因此被错误地设置为 NTFS 压缩。我正在尝试解压缩它。该文件当前正在由 Windows 服务进程使用。

我尝试使用文件资源管理器在目录级别清除压缩属性；我点击了“确定”，但几秒钟后又恢复了。虽然目录被标记为未压缩，但文件仍然被压缩并在窗口中显示为蓝色。

我也尝试使用COMPACT /U- 它也立即返回，并且似乎没有解压缩（尽管它似乎说它确实解压缩了）：

 E:\Services\MyService\Map>compact

 Listing E:\Services\MyService\Map\
 New files added to this directory will not be compressed.

27518828544 : 21974568960 = 1.3 to 1 C running.mmap
      235 :       235 = 1.0 to 1   test.txt

Of 2 files within 1 directories
1 are compressed and 1 are not compressed.
27,518,828,779 total bytes of data are stored in 21,974,569,195 bytes.
The compression ratio is 1.3 to 1.

The compression ratio is 1.3 to 1.

为什么会发生这种情况？系统是否在后台工作以解压缩文件，还是忽略了我的请求？这是 Windows 2003 Server。

答案1

这很可能只是时间问题。您清除了文件夹压缩，但文件有 25 GB。解压可能需要一些时间。
