Hi vineet, Winzip does not support rar format files. You need some rar extraction utility like 7-zip

Hi Arsh,

Glad you asked!,

with /b flag, we are copying in binary mode and + between image and secret file is that we are appending first file with second and placing the result in picture.jpg.

So basically two files are copied one after the other.
when image is opened in image viewer it just looking at image with some data appended.

If you change the order of image and secret zip file, things won’t work.

Hi
Can you please tell me where exactly is the secret msg stored in the picture? I mean in the header files or what?

And can any size .bmp file store data of any size?
Are there any limitations?
