Rules for "Date Modified" of folders in Windows Explorer
提问by Kevin Haines
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]
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资源管理器的角度提出的问题，但该行为可能对编码搜索/排序类型的活动有用]
Is there a definitive description of this anywhere - searches of Microsoft, MSDN, Google & Stack Overflow have been unsuccessful.
是否有任何地方对此的明确描述 - 对 Microsoft、MSDN、Google 和 Stack Overflow 的搜索均未成功。
Personal experiments seem to suggest that in a tree of folders:
个人实验似乎表明在文件夹树中：
- when a folder/file is added/deleted in a folder, the containing folder'sdate modified is updated.
- when the content of a file is modified, the containing folder is unaffected
- 在文件夹中添加/删除文件夹/文件时，将更新包含文件夹的修改日期。
- 当文件内容被修改时，包含的文件夹不受影响
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):
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（DD/MM/YYYY 格式的日期）运行：
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)

This is not explorer specific, this is NTFS-related.
这不是特定于资源管理器的，而是与 NTFS 相关的。

Note: Modified time can be disabled with filesystem option, so you should never rely on it. Any suggested reliable methods would be appreciated.
注意：可以使用文件系统选项禁用修改时间，因此您永远不要依赖它。任何建议的可靠方法将不胜感激。

Disclaimer: I tested all of these myself on Windows 10. I could not find an authoritative source documenting all of these behaviours. It is entirely possible that I made a mistake somewhere.
免责声明：我自己在 Windows 10 上测试了所有这些。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。
The folder's last modified time is updatedfor these actions:
文件夹的上次修改时间将针对以下操作进行更新：
- new file or folder directly in target folder
- renamed file or folder directly in target folder
- deleted file or folder directly in target folder
- hardlink create/delete/rename - same as files
- file/folder symlink create/delete/rename
- directory junction create/delete/rename
- 直接在目标文件夹中新建文件或文件夹
- 直接在目标文件夹中重命名文件或文件夹
- 直接在目标文件夹中删除的文件或文件夹
- 硬链接创建/删除/重命名 - 与文件相同
- 文件/文件夹符号链接创建/删除/重命名
- 目录连接创建/删除/重命名
It is not updatedfor these actions:
它不会更新这些行动：
- modified contents of file directly in target folder
- edit target of symlink or junction contained in target folder
- file's or sub-folder's created/modified date changing
- edit basic attributes (hidden/archive/system) of a direct child
- NTFS compression/encryption change of a direct child
- anything at all happening in a sub-folder - literally anything
- changing attributes of the folder itself
- changing owner/ACL of the folder itself
- owner or ACL of a direct child changing
- if the folder is a directory junction, changing the target
- adding/deleting alt data streams to a direct child file
- 直接在目标文件夹中修改文件的内容
- 编辑目标文件夹中包含的符号链接或连接的目标
- 文件或子文件夹的创建/修改日期更改
- 编辑直接子项的基本属性（隐藏/存档/系统）
- 直接子项的 NTFS 压缩/加密更改
- 子文件夹中发生的任何事情 - 几乎任何事情
- 更改文件夹本身的属性
- 更改文件夹本身的所有者/ACL
- 直接子项的所有者或 ACL 更改
- 如果文件夹是目录结点，则更改目标
- 将 alt 数据流添加/删除到直接子文件
