1) Add a zip file for hidden documents by winrar.
2) Take any jpg/gif picture of any size and Dimension. for ex. we take desert.jpg.
3) Now Copy both two Files (zip or picture) in Same Folder. Let’s say we have copied the file in C Drive.
4) Now open the Command prompt window. Move to the Destination Folder.
5) Just Type the following command:
copy /b desert.jpg + securefile.rar secureimage.jpg
Here desert.jpg is the name of the original image, securefile.rar is the name of the rar file we want to Hide, and secureimage.jpg is the name of the output image which contain both rar file and the image.
6) To get the original rar file, just rename secureimage.jpg to secureimage.rar and than extract it using 7-zip or Winrar.
