Hello Gabriel, this KDE Frameworks devel is for discussion around development *of* KDE Frameworks not *with* KDE Frameworks, your question belongs to kde-devel at kde.org

Is this question related to the code down below? or different?

You can't write a file *inside* a gz file, a gz is not multiple files, it's just one file (a .tar.gz is still just one gz file, it's the tar part that has multiple files).

Cheers,
