java - Windows 7 中的内部路径映射

Question

我有一台 windows7 机器，我在其中通过以下路径中的 java 代码创建一个文件

C:\Users\123\Application Data\XYZ

但实际上它是在这里创建的

C:\Users\123\AppData\Roaming\XYZ

请告诉我为什么？

Answer 1

因为一个是旧路径，另一个是当前首选文件夹路径。两者都通向同一位置。

参见例如Application Compatibility: Junction Points and Backup Applications :

In Windows Vista® and Windows Server® 2008, the default location of user data has changed. An example of this change is the Documents and Settings directory, which has been moved from %systemdrive%\Documents and Settings to %systemdrive%\Users.

和:

..\Documents and Settings\\Application Data\ [is mapped to] ..\Users\\AppData\Roaming
