The documentationdescribes the expected use of this folder like this (emphasis mine):
该文档描述了此文件夹的预期用途（重点是我的）：
The file system directory that contains application data for all users. A typical path is C:\Documents and Settings\All Users\Application Data. This folder is used for application data that is not user specific.For example, an application can store a spell-check dictionary, a database of clip art, or a log file in the CSIDL_COMMON_APPDATA folder. This information will not roam and is available to anyone using the computer.
包含所有用户的应用程序数据的文件系统目录。典型的路径是 C:\Documents and Settings\All Users\Application Data。此文件夹用于非用户特定的应用程序数据。例如，应用程序可以在 CSIDL_COMMON_APPDATA 文件夹中存储拼写检查字典、剪贴画数据库或日志文件。此信息不会漫游，任何使用计算机的人都可以使用。
Note that this documentation refers to the typical path as per older versions of Windows. In modern versions of Windows it is located in %SystemDrive%\ProgramData.
请注意，本文档指的是旧版 Windows 的典型路径。在现代版本的 Windows 中，它位于%SystemDrive%\ProgramData.
Rather disappointgly, the above quote is from the now legacy CSIDLdocumentation. But the documentation for the replacement KNOWNFOLDERIDomits the useful descriptions of what you are intended to do with these special folders. So, in order to get to the bottom of questions like this you need to refer to both topics, so far as I can tell.
令人失望的是，上面的引用来自现在的遗留CSIDL文档。但是替换文档KNOWNFOLDERID省略了您打算对这些特殊文件夹执行的操作的有用描述。因此，据我所知，为了深入了解此类问题，您需要参考这两个主题。
