My main use for Calibre is to convert personal .rtf files so that I can read them on my Kindle.
I have hundreds rtf files and they all use space-hyphen-space sequences and commas in their filenames. There is no author name or series name or anything else embedded in the .rtf filename: nothing except the full title. I'd like to instruct Calibre to keep the full filename as the full title--hyphens and spaces and all--without making any changes to it whatsoever (other than stripping away the ".rtf" file type).
Is there a simple way to do that? (Renaming my files is not an option: my filenames interact with other programs.)
