How to Hide a RAR File in JPG File !

First you need to have a rar file and a jpg image to hide the rar
Say the jpg is “image.jpg” and the rar is “file.rar”

Go to Windows command prompt (Start>Run>type cmd and press enter)

Now type this command:
copy /b image.jpg + file.rar newfile.jpg

switch “/b” indicates the copy function is binary
“newfile.jpg” is the resulting image with the rar file embedded (you can use a name of your choice)

That’s all

When you click on newfile.jpg the image will be displayed. Now it you change the jpg extension to rar (ie: newfile.rar) and open it with WinRAR the contents of the embedded rar file will be displayed.

The jpg can be replaced with a bmp,png,gif or swf file. The rar archive can be replaced with zip,tar.gz/bz2 or 7z archive. Actually in theory you can use any image format and any archive.

Here are some sample commands:
copy /b image.bmp + file.zip newfile.jpg
copy /b image.gif + file.7z newfile.jpg
copy /b image.png + file.tar.gz newfile.jpg
copy /b image.swf + file.rar newfile.jpg
