It varies by project and preference.  Working with very large files
can get cumbersome, but having a lot of small files means higher
amounts of editing hassle and more junk to keep track of.  

As a personal opinion, I'd say just try to keep your functions small
and understandable, and don't worry about file size until the files
start getting inconvenient to edit.  I find 1000-2000 lines is a
reasonable file size.
