Windows 7 文件日期问题
很抱歉没有提出严格的编程问题，但是一旦我的困惑消除了，这将转向编程。
我即将编写一个程序，可以修改文件日期戳，例如创建、修改、上次访问日期。
当我在 Windows 7 上进行调查时，它似乎提供了更多日期字段。 此处的示例图片 http://img534.imageshack.us/img534/1281/datee.jpg
操作系统到底存储了多少个文件属性？我想擦除所有日期字段，因此我需要知道哪些属性存储在文件中以及哪些属性是操作系统生成的。
感谢您的阅读。期待您的见解。
编辑：刚刚找到this 在网络上，这使得我想要的应用程序不值得开发。谢谢。
apologies for not asking a strictly programming question, but this will move on to programming once my confusion is cleared.
i am about to write a program that can modify file date stamps like created, modified, last accessed date.
as i am investigating on Windows 7, it seems to provide more date fields. example image here http://img534.imageshack.us/img534/1281/datee.jpg
exactly how many file attributes are stored by the OS? i want to wipe all date fields, so i need to know which attributes are stored in the file and which are operating system generated.
thanks for reading. look forward to your insights.
EDIT: just found this on the web, which makes my intended application not worth developing. thank you.

对于不同的数据类型，例如音频、视频和图像文件，操作系统将显示从文件头确定的附加数据。
例如，对于图像，它将使用包含有关快门速度的各种信息的 EXIF 数据，光圈等这里可能还有其他日期信息。
For different data types such as audio, video and image files, the OS will show additional data that it determines from the header of the file.
E.g., for images, it will use EXIF data that contains all kinds of info about shutter speed, aperture,etc. There may also be additional date info here.
