FileInfo.com
Well, I was wanting to know about a strange file type or file extension (suffix at the end of the file name) residing on my computer. I couldn't figure out the extension of the file and was left disappointed. Thus, I came across this pretty useful website FileInfo.com which contains a searchable database of thousands of file extensions with detailed information about the associated file types which they call as the "File Extension Registry".
Nonetheless, the coolest thing about this website is we can easily register our own file extensions. Thus, developers can submit their file extensions along with its information.
