Hi, Sorry for my english ! I have a double problem. I created a book, ID layout containing 148 pages. I have separated my layout in two parts, so two diferent files. At the bengining my client asked me to create a book and during the projetc he asked me to make it be an ebook to. so today I must create a book and an ebook with the same work. To creat e the book is okay. to create the ebook , i need to combine my two files in one; and then create an ebook. my double questions are : how to combine two id files in one ? can I create an ebook from a classique layout ? My version is InDesign CC 2021.
