Adding files to an IzPack .jar installer

I need to modify an installation package produced with IzPack 5.1.3.

In practice I have to update some files present in the installation package.

The package was not produced by me and therefore I don't have the original files to rebuild it.

I know that in the installer there is a Pack of IzPack, I would like to open this pack (it's a compressed file of some kind) and replace/add files to it.

I think I should use PackFile, PackInfo, Unpacker and DefaultFileUnpacker classes by IzPack, but I have no idea if it's feasible, nor how to proceed.

Here are a couple of image of what it is inside that .jar installer this is the content of /resources diurectory inside the .jar installer

this the pack file
