Files hiding inside a file with a mysterious way

Files hiding inside a file with a mysterious way

I know this looks crazy , but i'm pretty sure that you have a solution for
this!
and that's why i came here.


i have a file which ends with .p extension .
in decompression using WinRar's SFX with a configuration file (XML) it's
gonna extract those files!

Here we go..
i took a screenshot of the configuration file =>


And this is the screenshot of the .p file =>


Here you see the highlights i made in the pictures .. (1") and (2") in the
first and the second pic.

I really need those files right now , and i have them !! But can't just
use them !!
This file is one of 103 other files .. All have files inside that need to
extract !

Programatically, explain this to me ..
And generally please tell me how to take my files from those jails :-)

Your answer will not just make me use my files .. It's gonna give me an
idea of maybe an incoming project .

NOTE: This files was in ".exe" SFX and was damaged , i fixed the damage
and had to add it to an SFX again but i didn't know how to use the
configuration file and where.

Thank you :-)
