Good morning.
Sorry for not having posted my message in the correct section ! Thanks for the modification.
About the question, I am using highwind because i could add my own files (images/text files/etc.) so create a custom LGP archive.
The problem I am facing is that I don't know (in terms of C++ src code) how to get for instance 1 element of this archive and use it in a program.
I am using LGP because of the very performant compression it provides
Regards
Edit: I analyzed the lgp /unlgp source code but I doesn't seem that my answer is in there. Correct me if I mistake
