Sometimes we want to hide data (files) from other persons in our computer/Laptop. So no one can access this data due to security reason or some personal reason, for this we generally uses hidden property of files in Windows or create a file or folder using dot (.) in Unix or Linux operating system, but this isn't a safest way to hide your data.

"copy /b my.jpg+mydata.rar hidden.jpg"
my.jpg ->The image behind which you want to hide your data.
