是否可以删除在Windows下的进程打开的文件？ [英] Is it possible to delete a file that is opened by a process under windows?

问题描述

为了进行测试和模拟，我想删除目前由我的程序开启的档案。

For testing and simulation purposes I would like to delete a file that is currently open by my process.

CreateFile docs 说明可以在模式下打开文件（ FILE_SHARE_DELETE ），它允许打开句柄指向的文件被另一个操作删除。 （我已经尝试并通过CreateFile（FILE_SHARE_DELETE）+ DeleteFile确认了这一点。）

The CreateFile docs state that it is possible to open a file in a mode (FILE_SHARE_DELETE) that allows the file the open handle is pointing to to be deleted by another operation. (And I already tried and confirmed this via CreateFile(FILE_SHARE_DELETE) + DeleteFile.)

然而，我现在想知道的是，

What I would like to know now however is, whether it is possible at all that a file that is opened by anyone without above mentioned flag to be deleted somehow?

根据我理解的 DeleteFile docs 这不可能使用此功能，如

As far as I understand the DeleteFile docs it would not be possible with this functions, as

如果应用程序尝试删除对于普通I / O打开
或作为内存映射文件的文件，DeleteFile函数将失败。

The DeleteFile function fails if an application attempts to delete a file that is open for normal I/O or as a memory-mapped file.

有没有其他方法来删除已打开但未设置FILE_SHARE_DELETE标志的文件？

Is there any other way to delete a file that is open, but does not have the FILE_SHARE_DELETE flag set?

推荐答案

没有办法这样做。

最近的做法是在重新启动时使用 MoveFileEx ，目标文件名为 NULL 和 MOVEFILE_DELAY_UNTIL_REBOOT在 dwFlags 参数中。

The closest way to do something like this is to schedule delete on reboot using MoveFileEx with a target filename of NULL, and MOVEFILE_DELAY_UNTIL_REBOOT in the dwFlags parameter.
