I appreciate your response but it does not seem to be such a strange request when someone made an actual program to do so (Construct merger) Unfortunately that program is no longer supported so I was hoping for another option.
I purchased a template that I completely revamped and wanted to add it into my original game. But there are folders in the one I want to import like 'system' with arrays etc that won't copy and paste over.
Maybe someone else has another creative option. It seems I'm not the only one that has interest in this.
