JOIN TWO FILES INTO ONE.

First thing u need to do is to save files into same folder .

Now let name of one file be avi.jpeg and name of second file be 21961.bat and u want to merge them in 1 file named avinash.jpeg

then steps will be

1. Open command prompt
2. 
   
3. Now traverse to folder where u have saved the two files to be merged.
4. 
   
5. type command

copy /b avi.jpeg + 21961.bat avinash.jpeg

NOW just wait till u got message

1 file copied

go to the folder n u will find a new file named avinash.jpeg

If u double click this file the image avi.jpeg opens but it also invokes 21961.bat at the same time.

INSTEAD OF TYPING SOURCE FILE NAMES BY YOURSELF,JUST TYPE FEW CHARACTERS OF FILE NAME AND PRESS TAB........
