Reply To: .INDB question..will it help me on this project

I rarely use the book feature, so I’m no expert on that. The majority of my files are single file large documents (books).

But it sounds like using the book feature is exactly what you are looking for, especially since you want to sychronize the styles.

It would definitely be a pain if you had to open the other 29 files and change the styles manually (though you could open each and append the styles from the other file).
