Every one of us try to hide our secret files from Eagle eyes.There are many ways to keep your files secret by encrypting,hiding or even changing its attributes. However most of them requires to install some sort of software on your computer, which could then be spotted by someone else.
I have previously written about how to hide folders in win xp, But now i'm going to say you How to hide files inside a JPEG picture.
In order to accomplish this task, you will need to have either WinZip or WinRAR or any other compressing software installed on your computer. You can download either of these off the Internet and use them without having to pay anything. Here are the steps for creating your hidden files.
Step 1:Create a folder on one of your drivers, i.e D:\New folder and put all your files in that folder along with the image which you will be using to hide your files.
Step 2:Now select all the files you want to hide and create an archive using winrar or winzip(Do not select the pic).Now make a name for it.
Step 3:Now you have a rar or zip file like this.
Step 4:Now open your Command prompt(Start> Run > type "cmd">press "Enter").Now you can see the command prompt.Now go to the folder where it is located in your Harddrive as show in the image.
Step 5:Now type in the following line: “copy /b Mypic.JPG + Mysecret.rar Mypic.jpg” and press Enter. Do not use the quotes. You should get a response like below.
Taa daa you got it :D
Now select the new image and right click>openwith>winrar or winzip.Either way, you’ll see your hidden files show up that you can then extract out.
That’s it! That is all it takes to hide files inside JPG picture files! It’s a great way simply because not many people know it’s possible and no one even thinks about a picture as having to the ability to “hide” files. Enjoy!
Bullet points:
►Never use spaces or spcial charecters for file names or for images.
►Never forget to give right Extections like .ZIP or .RAR or .JPG etc..,
►Here /b refers to Binary data.
