Question

How many chapters in a book?

Is there a limit to the number of chapter files that can go into a single FrameMaker book?

I'm thinking that a few pages per chapter would work well when I export it to the web, but I'm wondering if 500 chapter files will choke book generation when I'm trying to make a PDF.

Does anyone have experience with this? I've built large (1,000 pages) manuals before, but never broken them down into such small chapters.

Advice appreciated.

AFAIK, there is no (practical) limit. The book file is essentially a pointer to the actual files. For a summary of known FM limitations/quirks Klaus Daube has compiled an excellent reference at:

The various versions of Windows have limits on the number of files open to a single process, which might be as low as 2048. Irrespective of the OS limit, the limit might as low as 500 if Adobe used a specific C library for file ops. DOS was 255, in case this is about FM3 on Win 3.1 .

But even this wouldn't be a problem as long as you avoid having every component file open at once. The Update Book and Print/Save-As appear to open only the book and one component at a time.

There doesn't appear to be any limit to the number of files in a directory in recent Windows, but more than a few thousand will get tedious to manage.

If I were planning a book with a bazillion chapters, I'd test it with dummy files first.
