获取文件移动datetime [英] Getting file move datetime

问题描述

当您复制文件（在Windows环境中）时，创建和LastAccess日期时间将被修改，并可以使用 FileInfo 对象检索。

When you copy a file (in a windows environment), the Creation and LastAccess datetime are modified and can be retrieved with a FileInfo object.

但是，当文件移入文件夹时，我找不到任何可靠的datetime（直接链接到一个文件）。当文件移动时，窗口是否更新任何datetime值（可以检索）？

However, I can't find any reliable datetime (directly linked to a file) that would be changed when a file is moved into a folder. Does windows update any datetime value in the file when it's moved (and can it be retrieved)?

注意
我是不是在死胡同，我有很多解决方法。我只是想知道这可以直接在文件级别处理，以避免不必要的逻辑。

Note I'm not in a dead end and I have many workarounds. I'm just wondering if this could be handled directly at the file level to avoid unnecessary logic.

推荐答案

所以这似乎是在Windows中如何工作：

So this seems to be how this works in Windows:

• 创建时间：如果目标文件已存在，其创建时间保存，否则设置为当前系统时间。始终从源文件的修改时间复制


• 上次修改时间。


• 上次访问时间始终设置为当前系统时间。

• Creation time: if the target file already exists, its' creation time is preserved, otherwise it is set to the current system time.
• Last Modification time: always copied from modification time of the source file.
• Last Access time: always set to the current system time.

RoboCopy 和 RichCopy 是几个可以使用/ DCOPY：T保存目录的mtime的命令行工具切换，但这只适用于Vista和更新版本。
可以保留时间戳的另一个复制实用程序是 XXCOPY

RoboCopy and RichCopy are couple of command-line tools that can preserve the mtime for directories with the /DCOPY:T switch, but this only works in Vista and newer. Another copy utility which can preserve timestamps is XXCOPY
