推荐答案

如果有内存可用，则在关闭文件时会更新时间.只需用几行代码即可确认.

If memory serves the time is updated when the file is closed. This should be fairly easy to confirm with a few lines of code.

根据GetFileTime()的文档 ^ ] Windows会同时记录创建时间和文件最后写入的时间.选择一个对您有用的.

According to the documentation for GetFileTime() [^] Windows records *both* the creation time *and* the time the file was last written to. Pick the one that''s useful to you.
