File Extensions

Figuring out what kind of file a particular file extension is referring to can be impossible without some kind of reference. There are literally thousands of different file extensions out there and you need more information on what kind of file it is before you can use it.

September/October 2009 Update: I'm currently populating the folders below so if you find any obvious omissions, that's probably why.

Browse through the alphabetical listings below to locate the file extension you need help with.
