File Format Wiki
The purpose of the File Format Wiki is to "Solve the File Format Problem". The File Format Problem in this context is that over the last century, many types of electronic information have been presented in formats that are non-intuitive and subject to the rapidly-shifting interests of what is newest and best. As a result, thousands of programs, documents, images and binary files are in danger of being unreadable to later generations as no readily available information about accessing them is to be found (source)
