Hide a .rar archive inside a jpg image

Yes boys and girls you read that correctly. You can hide a rar file inside a jpg file that will open the image when double clicked, through very clever command line shenanigans.

Let's check it out:

Grab your super secret .rar file, copy it to the same directory as your not so super secret jpg image. Let's use c:\test for our example.

Open up a command prompt by clicking Start/Run and typing "cmd" and click ok.
In the DOS window, type "cd c:\test" to navigate to our folder
Type "copy /b input.jpg + input.rar ouput.jpg
(input jpg is the picture that will show when it is opened, input.rar is the secret file you want to hide and output.jpg will be the name of the new combined file)

It is as simple as that!

You can double click the new file and it will show it as a picture, BUT… if you open it with winrar, you will see the files contained.
