防止另存为功能
我需要防止文档被保存/另存为（例如来自 ms word）。 我环顾四周，还没有找到令人满意的答案。 我考虑过 EFS...但我不认为它会阻止用户将文档另存为...（尽管它会阻止访问原始源文件）。 有什么想法吗？
I need to prevent a document from being saved / saved as (say from ms word). I've looked around and I havn't quite found a satifying answer. I've considered EFS... but I don't think it prevents the user from saving the document as... (though it prevents access to the original source file). Any ideas outthere?

在具有只读磁盘、没有网络且没有可移动驱动器的完全锁定的系统上运行它。 对计算机的访问也必须受到物理限制。
这应该会阻止“另存为”工作，但仍然不会阻止文档被复制（有人可能会拍摄屏幕照片并对其进行 OCR）。
Run it on completely locked-down system with read-only disk, no network and no removable drives. Access to the computer must be phisically restricted as well.
This should prevent Save As from working, but still won't prevent document from being copied (someone may take photo of the screen and OCR it).
通常不值得禁用“另存为”，因为您需要访问原始文件才能首先打开它。 总是有多种方法可以复制文件。
当有人要求我禁用 PDF 的另存为时，我遇到了同样的问题。
It usually isn't worth it to disable Save As, because you need access to the original in order to open it in the first place. There are always ways to copy a file.
I had the same issue come up when someone asked me to disable Save As for a PDF.
没有办法对任意文档进行修改而使其无法保存。 您可以修改 Word 等程序，不允许“保存”或“另存为”，但这仍然允许某人使用不同的程序或在不同的计算机上打开和保存文档。
There is no way take an arbitrary document and modify it in such a way that it cannot be saved. You could modify a program such as Word not to allow Save or Save As but that would still allow someone to open and save the document with a different program or on a different machine.
