Reply To: One file OR several files?

This is the very question I was about to ask on this forum!
Thank you for beating me to it!

I'm about to take on a larger book as well… For years I have been setting books up as separate files “per spread” for the same reason described above but these where usually only ~50 pagers. I cant imagine using this same method for ~250pg. Chapters seam to be a nice in between.

I'm also curious about these other approaches mentioned / i.e.: “chapter variables” and “manage them using book?”

I'm fairly new to Indesign so any advice on this would be huge!
