Kindly I ask your attention.
Start your browser, use different search engines and use different phrases:
Cfm extension
There you will find a lot of links to go for.
Cfm files is a Cold Fusion Markup file.
you should get it open with Notepad or any other text editor (it says).
Guess, Notepad++ anyway.
Try all the links, there might be something you might want to know.
