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:
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 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);
}
}
}
这样,就可以在Java和JNA中使用MFT列出所有文件和目录了。请注意,以上代码仅适用于Windows操作系统。对于其他操作系统,可能需要使用不同的方法来获取文件和目录的信息。
