In this example we will hide a text message inside a picture. We have choose for this tutorial a text file named Secret.txt and a picture firefox.jpg.
1. Move your files you want to combine in a new folder, in our case C:\Hidden.
2. Add the file you want to hide into a new RAR archive (in our example named Secret.txt.rar).
3. WinRar created the archive in the folder where our files are located.
4. Open Command Prompt (Start -> Run..., type cmd and press Enter).
5. Go to the folder where your files are located, in this case C:\Hidden by using the cd command.
6. Now type copy /b firefox.jpg + secret.txt.rar helpero.jpg where firefox.jpg is the original picture, secret.txt.rar is the file that will be hidden, and helpero.jpg is the file which contains both.
7. If you open helpero.jpg you will see the firefox.jpg image.
8. Try opening the file with WinRar (select All files).
9. Now you can see the text file that is hidden in the picture.
A simple solution to make this more secure, is to use encryption on the RAR file when your create it.

Wow, this article looks really cool. But does it really work?????? I sure hope so... Thanks a lot Cristian. Best wishes... SincerelyBHARAT.
you can also binary copy any file, including plain text in the same way, no need for the winrar step so "copy /b jpeg.jpg textfile.txt jpeg2.jpg". Views as a jpeg, but if you open jpeg2.jpg with Notepad, text file is at the bottom and readable , just thought it would be an alternative way
If the jpg file size is big then winrar or winzip says its not a valid archive file.When I used a 2MB file it coz this problem.But then I tried with 63KB file ... then it worked as expected... Thanks .. Rhythm :)
you can also add a mp3 file in the middle :) copy /b firefox.jpg whatever.mp3 secret.txt.rar helpero.jpg everything works the pic the song and the rar
that is awesomehttp://www.kidsolo.com

Computer forensic tools, such as EnCase will read the file header and determine the true nature of the file.EnCase also allows full text searches of compressed files.A better solution might be a steganography application.

Very cool! Also cool is encrypted file sharing which is a great way to exchange files secretly amongst friends without any ISP snooping: http://www.gigatribe.com

I think it is worth mentioning, that the key image file that should not be large in size or rar will report corrupted archive. 500kb is already large, but 100kb works fine.

very useful man, gonna try it out a bit. only question i have is that when you do this does the image file size increase by the size of the file it 'melds' with?
Matt, just try find the location of your Hidden Folder. I didn't understand how to find it either and I finally guessed it by typing "cd C:Hidden"
You people are simply genius!!!
can this work on files that aren't jpg like say mp3 or aiff?
