This is a cool trick with which you can hide your files inside a picture.
First select the files and compress them to zip or rar and place it in E: drive also place there the picture on which you want to hide the files.
Now go to command prompt and select E: drive by typing just E:
type this command
copy /b "file1.jpg"+"file2.zip" new.jpg
You are done when you double click the new file the picture will open
But when you right-click it and open it with winrar the hidden files will be shown
