"An innovative tool to analyse and identify computer file formats has won the 2007 Digital Preservation Award. DROID, developed by The National Archives in London, can examine any mystery file and identify its format. The tool works by gathering clues from the internal 'signatures' hidden inside every computer file, as well as more familiar elements such as the filename extension (.jpg, for example), to generate a highly accurate 'guess' about the software that will be needed to read the file. . . .
"Now, by using DROID and its big brother, the unique file format database known as PRONOM, experts at the National Archives are well on their way to cracking the problem. Once DROID has labelled a mystery file, PRONOM's extensive catalogue of software tools can advise curators on how best to preserve the file in a readable format. The database includes crucial information on software and hardware lifecycles, helping to avoid the obsolescence problem. And it will alert users if the program needed to read a file is no longer supported by manufacturers.
"PRONOM's system of identifiers has been adopted by the UK government and is the only nationally-recognised standard in its field."
