现在的问题是:如何在 Java 中获取此目录?

Now the Question: How can I get this Directory in Java?

因为 System.getProperty("user.home").concat("\\Music") 导致 "C:\Users\GG\Music" 而不是 "D:\GG\音乐".

Because System.getProperty("user.home").concat("\\Music") leads to "C:\Users\GG\Music" and not to "D:\GG\Music".

更新:

如安德斯的回答:

对我有用的方式是以下 3 行代码:

The way that worked for me were the following 3 lines of code:

char[] pszPath = new char[WinDef.MAX_PATH];
Shell32.INSTANCE.SHGetFolderPath(null, ShlObj.CSIDL_MYMUSIC, null, ShlObj.SHGFP_TYPE_CURRENT, pszPath);
File f = new File(String.valueOf(pszPath).trim());

推荐答案

在 Windows 上获取特殊文件夹路径的正确方法是调用 shell 函数，如 SHGetFolderPath 和 CSIDL_*code> 常量(在您的情况下为 CSIDL_MYMUSIC).

The correct way to get the path to special folders on Windows is to call a shell function like SHGetFolderPath with the CSIDL_* constants (CSIDL_MYMUSIC in your case).

您需要在 Java 中使用 JNI 或 JNA 来执行此操作.示例可以在此处和此处.

You need to use JNI or JNA in Java to do this. Examples can be found here and here.

为了完整性，从注册表读取是不正确方法做到这一点...

And for completeness, reading from the registry is not the correct way to do this...
