“修改日期”的规则 Windows 资源管理器中的文件夹数量
Windows 资源管理器如何确定文件夹的“修改日期”字段？ [旁白：我知道这是从特定于浏览器的角度提出的问题，但该行为可能对编码搜索/排序类型活动有用]
是否有对此的明确描述 - Microsoft、MSDN 搜索、谷歌和 堆栈溢出没有成功。
个人实验似乎表明，在文件夹树中：
- 当在文件夹中添加/删除文件夹/文件时，包含文件夹的修改日期会更新。
- 当文件的内容被修改时，包含的文件夹不受影响
但是，我正在查看一些似乎不符合这些基本规则的目录 - 沿着我拥有的树运行（日期为 DD/MM/YYYY 格式）：
folder (date created: 2/2/2006, date modified: 2/3/2006)
folder (date created: 2/2/2006, date modified: 2/3/2006)
folder (date created: 2/2/2006, date modified: 1/6/2009)
file (date created: 27/3/2009, date modified: 2/2/2006)
How does Windows Explorer determine the "Date Modified" field for folders? [Aside: I know this is asking from an explorer-specific perspective, but the behaviour could be useful to coding search/sort type activities]
Is there a definitive description of this anywhere - searches of Microsoft, MSDN, Google & Stack Overflow have been unsuccessful.
Personal experiments seem to suggest that in a tree of folders:
- when a folder/file is added/deleted in a folder, the containing folder's date modified is updated.
- when the content of a file is modified, the containing folder is unaffected
However, I'm looking at some directories that don't seem to conform to these basic rules - running down the tree I have (dates in DD/MM/YYYY format):
folder (date created: 2/2/2006, date modified: 2/3/2006)
folder (date created: 2/2/2006, date modified: 2/3/2006)
folder (date created: 2/2/2006, date modified: 1/6/2009)
file (date created: 27/3/2009, date modified: 2/2/2006)

这不是特定于浏览器的，而是与 NTFS 相关的。

This is not explorer specific, this is NTFS-related.
See

免责声明：我自己在 Windows 10 上测试了所有这些行为。我找不到记录所有这些行为的权威来源。 我完全有可能在某个地方犯了错误。
针对以下操作更新文件夹的上次修改时间：
以下操作未更新：

The folder's last modified time is updated for these actions:
