尝试在Java和JNA中使用MFT列出所有文件和目录

在Java和JNA中使用MFT列出所有文件和目录，可以通过以下步骤实现：

MFT（Master File Table）是Windows操作系统中的一个特殊文件，它记录了文件系统中所有文件和目录的元数据信息。通过读取MFT，可以获取文件和目录的详细信息。
首先，需要使用JNA库来调用Windows API函数，以便访问MFT。JNA是一个Java库，可以用于在Java中调用本地操作系统的函数。
在Java中，首先需要定义一个接口，用于声明要调用的Windows API函数。例如，可以创建一个名为"Win32"的接口，并在其中声明"FindFirstFile"和"FindNextFile"函数。

import com.sun.jna.Native;
import com.sun.jna.Structure;
import com.sun.jna.win32.StdCallLibrary;

public interface Win32 extends StdCallLibrary {
    Win32 INSTANCE = (Win32) Native.loadLibrary("kernel32", Win32.class);

    boolean FindClose(int hFindFile);

    int FindFirstFile(String lpFileName, Win32.FIND_DATA lpFindFileData);

    boolean FindNextFile(int hFindFile, Win32.FIND_DATA lpFindFileData);

    public static class FIND_DATA extends Structure {
        public String cFileName;
        public int dwFileAttributes;
        public int dwReserved0;

        public int dwReserved253;
        public int dwReserved254;
        public int dwReserved255;
    }
}

接下来，可以编写Java代码来调用这些函数，以列出所有文件和目录。以下是一个示例代码：

public class MFTExample {
    public static void main(String[] args) {
        Win32.FIND_DATA findData = new Win32.FIND_DATA();
        int hFindFile = Win32.INSTANCE.FindFirstFile("C:\\*", findData);
        if (hFindFile != -1) {
            do {
                System.out.println(findData.cFileName);
            } while (Win32.INSTANCE.FindNextFile(hFindFile, findData));
            Win32.INSTANCE.FindClose(hFindFile);
        }
    }
}
