Check if a file contains another file

I'm talking about Windows PE files. Is there a way to check if one file contains another? I mean... What if I merge two programs like this

MZ header 1st program
PE header 1st program
.
.
. all the sections from 1st program
.
MZ header 2nd program
PE header 2nd program
.
.
. all the sections from 2nd program
.

into one runable program? Of course, only the first one would run.

In your case, you'd first want to get the offset and size information about the last section of the PE file(IMAGE_SECTION_HEADER). Once you have this information, you can read the chunk after (offset + size), and if it matches with another PE format (MZ magic number), then it would suggest that there is a second file appended to the first.
