I should have been more explicit. The title of the book, as it shows in Calibre's interface, is being truncated when naming the file. For example, say the title of the book in Calibre is "This Is One Heck of a Long Filename and Will Demonstrate the Problem", and the author of the book is "I. M. Author." When Calibre saves the file, it truncates the name of the book to "This Is One Heck of a Long File" and then adds the author name, so that the file ends up being called something like "This Is One Heck of a Long File - I_ M_ Author.epub". The part of the filename that is created from the book title is now truncated to 31 characters, whereas previously it used (approx.) 36 characters (I believe it was 36 characters, but I haven't counted in a while. It was definitely more than 31 characters.). Anyway, I have ended up with duplicate filenames because of this, but only on l-o-n-g book names.
