Hide zipped file in a jpg/jpeg picture file!

Hi Everybody! Here is a simple trick that can help us sometimes..

Well this can be used to do a simple hide out for some essential documents that u may not otherwise want to be made available in ur computers hard drive open to all.. :) ..If you need to hide some compressed file (rar) in a jpg file then here is the tip to do so. Let's say I have a document Lloyds.pdf that I want to hide and a picture file (.jpg) called Star.jpg. Then we can infact hide our Lloyds.pdf inside the picture file so that if anybody opens it up he/she views only the picture file and not the pdf.

So here we go -
1. Copy the pdf file and the jpg file into a folder called Hack say in F drive.
2. Compress the pdf file to Lloyds.rar. (Use Winrar for the same).
3. Now open the command prompt.
4. Navigate to the respective directory - F:\Hack.
5. Now type the simple command - copy /b Star.jpg+Lloyds.rar Jinx.jpg. Press Enter.
6. Job Done!

Exit the command prompt.

Check the directory, there must be a jpg file called Jinx.jpg available. Try opening it, we can see the picture file. Now to get back the pdf, open Winrar and drag drop the Jinx.jpg file into the Winrar window and here u go. Winrar shows us the pdf file. Extract it, our pdf is safe and sound.

Note - I have tried to perform some experiements with this but found that Winzip isn't doing the job for us so thats why i mentioned winrar specifically above. Also keep that in mind that as our copy program just attached the two files one after the other so the size of the final file has increased. So hide only those files like this, so that no one suspects the size of the final image... in other words small compressed files... N yes Don't use this tip to hide office documents which are confidential... Let ur conscience rule u but in a positive way... Happy implementing.. :) ..
