识别Java中磁盘类型的文件系统格式，例如ntfs，fat16 / 32或ext

注意：这仅对在Windows系统上运行的Java有效：

使用JNA，您可以调用Win32 Kernel32的 GetVolumeInformation（） 来检索
lpFileSystemNameBuffer 参数，该参数

receives the name of the file system, forexample, the FAT file system or the NTFS file system

Kernel32.java ：

package filesystem;import java.util.HashMap;import java.util.Map;import com.sun.jna.Library;import com.sun.jna.Native;import com.sun.jna.platform.win32.WinDef.DWORD;import com.sun.jna.ptr.IntByReference;import com.sun.jna.win32.StdCallLibrary;import com.sun.jna.win32.W32APIFunctionMapper;import com.sun.jna.win32.W32APITypeMapper;public interface Kernel32 extends StdCallLibrary {    final static Map<String, Object> WIN32API_OPTIONS = new HashMap<String, Object>() {        private static final long serialVersionUID = 1L;        { put(Library.OPTION_FUNCTION_MAPPER, W32APIFunctionMapper.UNICODE); put(Library.OPTION_TYPE_MAPPER, W32APITypeMapper.UNICODE);        }    };    public Kernel32 INSTANCE = (Kernel32) Native.loadLibrary("Kernel32", Kernel32.class, WIN32API_OPTIONS);        public boolean GetVolumeInformation( String lpRootPathName, char[] lpVolumeNameBuffer, DWORD nVolumeNameSize, IntByReference lpVolumeSerialNumber, IntByReference lpMaximumComponentLength, IntByReference lpFileSystemFlags, char[] lpFileSystemNameBuffer, DWORD nFileSystemNameSize );    public int GetLastError();}

VolumeInformation.java ：

package filesystem;import ping.Kernel32;import com.sun.jna.platform.win32.WinDef.DWORD;import com.sun.jna.ptr.IntByReference;public class VolumeInformation {    static void getFileSystemName(){        char[] lpVolumeNameBuffer = new char[256];        DWORD nVolumeNameSize = new DWORd(256);        IntByReference lpVolumeSerialNumber = new IntByReference();        IntByReference lpMaximumComponentLength = new IntByReference();        IntByReference lpFileSystemFlags = new IntByReference();        char[] lpFileSystemNameBuffer = new char[256];        DWORD nFileSystemNameSize = new DWORd(256);        lpVolumeSerialNumber.setValue(0);        lpMaximumComponentLength.setValue(256);        lpFileSystemFlags.setValue(0);        Kernel32.INSTANCE.GetVolumeInformation(     "C:\",      lpVolumeNameBuffer,      nVolumeNameSize,      lpVolumeSerialNumber,      lpMaximumComponentLength,      lpFileSystemFlags,      lpFileSystemNameBuffer,      nFileSystemNameSize);        System.out.println("Last error: "+Kernel32.INSTANCE.GetLastError()+"nn");        String fs = new String(lpFileSystemNameBuffer);        System.out.println(fs.trim());    }        public static void main(String[] args) {        getFileSystemName();    }}
