Get Windows Special Folders (JNA) Tag(s): JNI/JNA
JNA (Java Native Access) provides Java programs easy access to native shared libraries (DLLs on Windows) without writing anything but Java code - no JNI or native code is required.
In this HowTo, we retrieve the path of some Windows Special Folders : Program Files, Common Documents and the Desktop.
You can get the others by using the right identifier from the constants defined in the ShlObj interface.
import com.sun.jna.Native;
import com.sun.jna.platform.win32.Shell32;
import com.sun.jna.platform.win32.ShlObj;
import com.sun.jna.platform.win32.WinDef;
// https://github.com/twall/jna#readme
// you need 2 jars : jna-3.5.1.jar and platform-3.5.1.jar
public class GetFolderPathDemo {
public static void main(String[] args) {
char[] pszPath = new char[WinDef.MAX_PATH];
Shell32.INSTANCE.SHGetFolderPath(null,
ShlObj.CSIDL_PROGRAM_FILES, null, ShlObj.SHGFP_TYPE_CURRENT,
pszPath);
System.out.println(Native.toString(pszPath));
Shell32.INSTANCE.SHGetFolderPath(null,
ShlObj.CSIDL_DESKTOPDIRECTORY, null, ShlObj.SHGFP_TYPE_CURRENT,
pszPath);
System.out.println(Native.toString(pszPath));
Shell32.INSTANCE.SHGetFolderPath(null,
ShlObj.CSIDL_COMMON_DOCUMENTS, null, ShlObj.SHGFP_TYPE_CURRENT,

System.out.println(Native.toString(pszPath));
