Questions
Just to be clear, I m not looking for the MIME type.
Let s say I have the following input: /path/to/file/foo.txt
I d like a way to break this input up, specifically into .txt for the extension. Is there any built in way to do this in Java? I would like to avoid writing my own parser.

Here is an example of how to use it (you may specify either full path or just file name):
String ext1 = FilenameUtils.getExtension("/path/to/file/foo.txt"); // returns "txt"
String ext2 = FilenameUtils.getExtension("bar.exe"); // returns "exe"
