Once Kotobee Author is opened, a new book is created. You are shown the following screen.
To proceed with the newly created book, simply close this dialog box. By default, a new chapter is created for you in reflowable layout. In case you'd like to change to a fixed-layout, click on Fixed layout in the dialog box.
Opening an existing project
If you wish to use an already existing project file, either click on Open (KPUB2, EPUB) in the startup dialog box, or select Open (KPUB2, EPUB) from the top File menu. Kotobee Author project files (extension KPUB2) are based on EPUB format. Hence you can simply open any EPUB file into Kotobee Author. Choose the file you want to use and click Open.
Importing from existing documents
The startup dialog box has buttons for importing PDF and HTML to conveniently assist you. At any time in future, you may import content from PDF, HTML, or Word files by selecting Improve From from the top File menu.
Saving your work
To prevent loss of your work, it is recommended to Save your file or Save As, if you wish to save your work under a new name. Kotobee Author periodically makes copies of your files in a temporary folder, in case the software is closed in an inappropriate way (e.g. power-cut, or hardware shutdown). On the next run of Kotobee Author, a dialog box would ask you if you would like to restore the previously opened content.
You will also realize the option Optimize and save in the File menu. This will attempt to remove any unused assets in your ebook (such as images, video, audio) that are no longer referenced in the content, in order to reduce the project's file size.
