Hide your files/folders in an image file using DOS command

Most of us are unaware with it...
"Copy" command is known to everyone,what it is ??
ahhhhhhhhhh,,its for to copy data from source to destination !!
is it ??
No !
then ??
to see the magic of COPY command u required an image file,any compression software like Winrar,Winzip etc,,
ohhhhh,,i know u have !! (pirated one)
now open a command prompt...

Command > copy \b Image_File+Winrar_File Destination_File

Image_File : in which u want to hide folder/file
Winrar_File : targeted folder/file to hide ,but first required to compress it.
Destination_File : any file name but make sure extension of Destination_File same as Image_file.

confused ??
Here is an Example !!

First,you zip that file or folder which u want to hide.
Suppose,it is a folder named Top_Secret_007 ,after compressing by winrar its Top_ Secret_007.rar....
image file is Evil.jpg

Command > copy \b Evil.jpg+Top_ Secret_007.rar Top_Evil.jpg

when u double click on the newly generated image file it will show u the original image file (for our example its Evil.jpg) and if u want to recollect all ur data which u hided in this image file,just required to open a software that u used to compress (in our example its winrar) and click on 'Open archive' and just locate that newly generated file,by extracting it u can get ur original data.

isn't it funny ??do ur comments on it !!!
