I'm using Moodle 3.0.3 on a Gentoo linux operating system. It is installed on a Raspberry Pi 2 Model.
In a course I created a Moodle Book. I added to it so far one chapter with few sub chapters.
Further chapters want to import into this book.
I created a folder for this purpose on my desktop machine. In this folder there are subfolders and html files. I compressed these in to single ZIP file ( attached here too ).
When in Moodle Book, when want to import this ZIP file as a chapter, I get error message:
Cannot find chapters in selected file
What am I missing here?
