Bibfilex is a free bibliographic manager for GNU/Linux, Windows and OS X. It's useful to create and to manage archives of bibliographical items with possible attachments of any kind according to Biblatex structure and rules, even if it can be used also with a wordprocessor like Writer or Word. Bibfilex is far less advanced than other bibliographic managers like JabRef or KBibTex, and allows only few customizations. Its strength is simplicity and speed, since it's a compiled software and uses a fast database, Sqlite, to store data. Furthermore, it run natively on GNU/Linux with GTK or Qt libraries, on Windows and OS X with Carbon libraries. The most interesting characteristic of Bibfilex is the possibility to replace the \cite and the \printbibliography commands within a Latex document with extended citations and bibliography, which are composed according to a user defined pattern, and possibly to convert the resulting file in other formats with Pandoc (http://johnmacfarlane.net/pandoc) or other similar software. Bibfilex has been written in Free Pascal with Lazarus, and is released under the GPL v. 3 licence. Other information are available in https://sites.google.com/site/bibfilex.
