The National Archives in the UK has released new versions of PRONOM, an online registry of file formats, software, and other technical information used for digital preservation purposes, and DROID (Digital Record Object Identification), software that is used to identify file formats in batch mode. DROID requires the Java Runtime Environment (version 1.5.0 or later), and it runs under Windows (Windows 2000, XP, and Vista), OS X, and Linux.
