如何防止删除文件 [英] how to prevent from deleting a file

问题描述

Windows将阻止您删除正在运行的程序正在使用的文件.

Windows will prevent you from deleting a file that''s in use by a running program.


how can i implement in my application for a file.

推荐答案

我的建议可能是一种解决方案，而不是一种好的解决方案，但我可能只是打开一个该文件的句柄，从而从OS角度将其标记为正在使用中，直到应用程序退出后才释放该句柄.如果您试图随时在操作系统中使该文件不可删除，即使您的程序未运行，我也不确定是否可以完成.

My suggestion may be more of a hack-solution than a good one, but I would possibly just open a handle to the file, thus marking it in use from the OS perspective, and not release the handle until the application exits. If you are trying to make the file undeletable in the OS at any time, even when your program is not running, I''m not sure it can be done.
