From the developer:
Have you ever had to work with Windows™ notepad, for whatever reason, and found yourself frustrated that it only has filters for Text Documents (*.txt) and All Files. And you need to look at *.log files or *.cpp files or some other extentsion, and wished you could filter the file list. CFDButton is very easy to install and use, and all of it settings are stored locally in xml files, so it works well on portable devices like USB thumb drives.
