推荐答案

您需要使用文件系统过滤器驱动程序才能拒绝写入或删除.您可以编写自己的文件(完成此工作需要6-9个工作月)，也可以使用我们的 CallbackFilter 产品，可让您在大约一个小时内完成任务.

You need to use a file system filter driver in order to deny writing or deletion. You can write your own (6-9 man-months of work to get it right), or you can use our CallbackFilter product, which lets you complete your task in about an hour.

请记住，操作系统没有文件复制"操作.文件复制是文件打开/文件读取/文件写入/文件关闭操作的顺序.

Remember, that the OS doesn't have "file copy" operation. File copying is a sequence of file open/file read/file write/file close operations.
