how to hide files with in mp3 or music files[TUTORIAL]

THROUGH THIS METHOD YOU CAN HIDE FILES  IN A mp3 file

You will need these things:
1) A mp3 file to hide stuff in
2) Files to be hidden
3) A file compression software(WINRAR)
4) Command Prompt

now follow my steps
step1:The first thing you will do is make a new folder on the any drive. I will call this folder "folder". Inside this folder, place the files to be hidden and the picture that will hide everything. The mp3 file that will hide everything in it cannot have any spaces in the name, so I called it "music".

step2:
You will now make a compressed file. THIS IS ESSENTIAL! 

Open your file compression software, and navigate to the folder you made. Make the files that will be hidden into a zipped file, and name it something simple, like "hide.rar".

I now have, in the "folder" folder, a music file named "music.mp3" and a compressed file called "hide.rar".
step3:
Open CMD by going to Start, All Programs, Accessories, Command Prompt orStart, Run, and type CMD. Type the following into the window that pops up:

now navigate to drive where you have placed the .rar file and .mp3 file
let the drive be D
now click on the top of the window and type cmd
like shown in pic


copy /b music.mp3 + hide.rar NEWMUSIC.mp3

copy /b: This makes a binary copy of the files music.mp3 and hide.rar

the new file will be created as NEWMUSIC.mp3 .
to retrieve hidden files you need to open compression software and drag the music
you will find the hidden content there
UPDATE
you can do for picture and video files too
