how to send .exe file from emails or hiding ur data

[navigator.007]

hi everyone
we cannot send an .exe file from our email directly
so first compress ur .exe file in .rar such as xyz.rar
and select a image such as abc.jpg
keep both file in same folder for ur ease
now open command prompt and move to the directory of where u placed abc.jpg and xyz.rar
and type : "copy /b abc.jpg + xyz.rar abc.jpg" and press enter
this is called binary copy /b is used for binary copy
now when u open abc.jpg , it open as original but when u rename it extension to .rar
it have the same data as contained by xyz.rar

by this u can also hide ur data in images
