• Open CMD in the directory which contains both files using the 10th item in this list or use the ;;;;cd ;;;;command to change the directory

• Use command ;;;;copy /b <;;;;RAR_filename>;;;;.rar+<;;;;image_filename>;;;;.<;;;;extension>;;;;<;;;;result_filename>;;;;-<;;;;extension>;;;;-In our case, we used ;;;;copy /b modules.rar+wave.png test2.png

Note: make sure you enter the RAR file first followed by the other file, else you won’t be able to recover the RAR package. The method also works on most common file types including documents and PDFs as long as you add the archive file first.

• This will generate the result file, which in our case is ;;;;;test2.png

This PNG file ;;;;displays as a normal image file ;;;;but when you ;;;;open it with WinRAR ;;;;or any other extraction tool, it ;;;;will extract the RAR file ;;;;which is buried under the image file. This is a good way of saving your sensitive files from curious friends or co-workers or even prevent them from being misused even in case of a data breach.
