将多个jpg文件与单个文件分开

Question

I have merged multiple jpeg files into one single .bin file.

.....
.........
while(true){
             if (q.numOfFiles() > 0) {
              source = q.getNextFile();
              in = new DataInputStream(new BufferedInputStream(new FileInputStream(source)));
               byte[] buf = new byte[1024];
               int len;
               while ((len = in.read(buf)) > 0) {
                out.write(buf, 0, len);
               }
               String s = "filename=="+source.getName()+"==filename";
               out.write(s.getBytes());
               out.flush();
               System.out.println("merged--"+source.getName());
             }
                }
........

as you can see i am appending "filename=="+source.getName()+"==filename" after end of each file. Now i want to separate all those jpegs with their actual file names. How can i read the separators that I've inserted in the merged files ?
