all files in one exe

Hi!
I am using NSIS and I have succesfully created an installer.
I have a directory with files in the same folder as the installer exe and with the command CopyFiles I copy those files into the chosen directory..

But what I would like to do is to have all those files imbeded in the exe file.. How do I do that? I looked thought the documentation without any luck..

I hope you can help me! Thanks in advance!

you have to use the File command
