Another interesting site.

http://www.openwith.org/
It gives you a free program to open many file extensions

 

Looks like a handy tool but does not work on 64bit systems.

 

Another one is :-

Common File Extension finder.
Link is http://www.fileinfo.net/extension/bin

Example
# A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

For example R File Extensions.

File types with example extensions that start with the letter R.

Extension File Type File Description
.r Audio Right Audio Channel File
.r Developer R Script File
.r00 Compressed WinRAR Compressed Archive
.r01 Compressed WinRAR Split Archive Part 1
.r02 Compressed WinRAR Split Archive Part 2
.r03 Compressed WinRAR Split Archive Part 3
.r1m Audio RealOne Streaming Media File
.ra Audio Real Audio File
.rad Text Radar ViewPoint Radar Data
.raf Image Fuji RAW Image File
.ram Audio Real Audio Media
.rar Compressed WinRAR Compressed Archive

Might come in useful as an alternative.
