How to hide any file inside into the JPEG or GIF file

We can easily place video clips, pdf, mp3, text files, Office documents, zipped files, webpage or any other file format inside a JPEG/GIF image.
And when a suspecting user tries to open that jpeg/GIF file [with concealed/Hidden information] with a photo editing software or with Paint, User would not be able to make out if this disguise jpg file is different from any standard jpg image.
Suppose you want to hide some confidential word documents from your friends. What you can do is convert that file into a regular jpg image so even if anyone double-clicks this file, all user will see is a preview of the image and nothing else.
Here is the trick on How to do it:-
1) Just zip the various word Documents into one rar File.
2) Take any jpg/gif picture of any size and Dimension.
3) Copy the two Files in Same Folder. Let’s say we have copied the file in D: Drive.
4) Now open the Command prompt window. Move to the Destination Folder, in this case we will just type
d: and press enter (as our rar file and image are saved in D: drive)
5) Just Type the following command:

copy /b image.jpg + hide.rar newimage.jpg
(Here image is the name of the original image,
hide.rar is the name of the rar file we want to Hide,
and new_image is the name of the disguise image which contain both rar file and the image)

6) To get the original rar file, just rename newimage.jpg to newimage.rar and than extract it using 7-zip or Winrar.
Similarly we can hide other files like videos, mp3 and other secret documents.
Just Zip all the Files into Single rar files and Follow the above Steps.

That’s it!!!
