This tutorial will show you how to hide .rar files within .jpg files - so that anyone who opens the picture would never know there was another file hidden within it.

  1. Select the RAR file that you want to hide. For this example the file I want to hide is called files.rar and the picture I’m going to hide it in is called warren.jpg. Copy both the files into the same folder.
  2. Then open the command prompt by selecting Start -> Run -> in the space provided enter cmd and click OK.
  3. Navigate to the the folder that you stored the files in. I kept them in the Downloads folder found within my My Documents folder, so I issued the commands cd “My Documents” and then cd Downloads. Now type the following command: copy /b warren.jpg + files.rar warren2.jpg Remember - replace warren.jpg, files.rar and warren2.jpg with the names of your files.

  5. This will embed the archive thus hiding it. You can open warren2.jpg with a picture viewer and there will be no indication that there’s a .rar file hidden within it.
  6. To open the hidden archive (.rar file), simply open warren2.jpg (your picture) with WinRAR, or the RAR decompression utility of your choice.
  7. NOTE: you may need to select All Files when opening your picture file with WinRAR, otherwise it won’t be listed in the directory view.
  8. Now you can extract the “hidden” files from your “hidden” RAR file.

    Sorry… It doesn’t work for me. I obtain an error message says: “The archive is either in unknown format or damaged”. The same results with other rar application. Can you help me?

    The *NIX (e.g. Ubuntu) way of doing this would be:

    cat warren.jpg files.rar warren2.jpg

    You should then be able to extract warren2.jpg with unrar (or a graphical frontend).
