问题

超级用户读者boboes想知道在Windows 7和更新版本中是否有一个内置方法来锁定文件并防止其被覆盖或删除：

Is there a way to lock a file with in-house means so that it cannot be deleted or overwritten? I need to temporarily lock files while testing copy scripts in order to check the error handling in those scripts. Until Windows XP, I would load a file in debug.exe to lock it. Is there a way to do this in Windows 7 and newer editi***?

I know that there are programs for doing this. My question is if there is a built in mechani** in Windows 7 and newer editi***. Sometimes I have to check a script on a PC and do not want to install new programs for that.

There are also some good suggesti*** here: How to purposefully exclusively lock a file? Unfortunately, they require 3rd party tools or changing the file to a locked state.

在Windows7和更新版本中是否有内置的方法来执行此操作？

答案

超级用户贡献者丹和突破为我们提供了答案。首先，丹：

I think PowerShell is probably the neatest way to accomplish this. Something like the following:

While paused, the above script causes the following prompt when attempting to open up “myfile.txt”:

接着是突破的答案：

For the curious, here is the MSDN link to the File::Open method detailing the parameters of the call (specifically, the last argument ‘None’, declines sharing the file with any other threads/processes). Likewise, provisi*** exist to lock the file for read/write only, or a combination thereof.
