Hide your files in jpeg File without any Software!

This is quite an old trick but still works fine. Its a type of stenography technique where we try to hide a file inside another file.    
You will only need to download WinRAR & install it.


1.  Gather all the files that you wish to hide in a folder anywhere in your PC (make it in
C:\hidden ).
2.  Now, add those files in a RAR archive (e.g. new.rar). This file should also be in the
same directory (C:\hidden).
3.  Now, look for a simple JPEG/JPG picture file (e.g. logo.jpg). Copy/Paste that file also in
C:\hidden.
4.  Now, open Command Prompt (Go to Run and type ‘cmd‘). Make your working
directory C:\hidden, execute cd C:\hidden.
5.  Now type: “COPY /b logo.jpg + new.rar secret.jpg” (without quotes) - Now,
logo.jpg is the picture you want to show, new.rar is the file to be hidden, and secret.jpg is the file which contains both (/b  option is used for combining file to the binary level).
6.  Now, after you have done this, you will see a file secret.jpg in C:\hidden. Open it
(double-click) and it will show the picture you wanted to show. Now try opening the
same file with WinRAR, it will show the hidden archive...
This hack will allow you to hide files in jpegs's without software installed. I have tested it in XP/Vista, not sure about Windows7.
