The brief section above the Structure and Project Files’ tables includes the word count for the full project’s output (the PDF) as well as the file count for the total number of included subfiles in your project. This will include the root file file as well as images or any other data files Texifier recognises as part of the project.
The Windows variant of this article will be updated in due course. To try out Texifier for Windows before it is publicly released, please sign up for a beta.
