Renaming files the indesign in a book

[uniq1]

How can I add an additional word to the end of my file names in the book? Thanks...

Hi @uniq1 ,

you have to rename the InDesign document in the file system, add it again to the InDesign book file and remove the old named InDesign document from the InDesign book file.

Before you this disable the synchronizing of page numbers in the InDesign book file!

Thank you @Laubender 
Yes I can do this manually. I want to add additional text to the end of all my files in the book. Of course it would be great if I could also remove the old file.
