.QFS文件的mime类型是什么，或者如何在不提及mimeType的情况下写入SD卡

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

public class SDCardWriter {
    public static void main(String[] args) {
        String filePath = "/sdcard/myfile.txt"; // 要写入的文件路径
        String data = "Hello, World!"; // 要写入的数据

        File file = new File(filePath);
        FileOutputStream fos = null;

        try {
            fos = new FileOutputStream(file);
            fos.write(data.getBytes());
            fos.flush();
            System.out.println("数据成功写入SD卡！");
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (fos != null) {
                try {
                    fos.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
