There is only one file type that uses the .WFSP extension:
Wondershare Fantashow Project
A WFSP file is a video project created by Fantashow, a video editor used to make home movies. It contains project elements, which includes references to imported video, audio, and images that have been imported. WFSP files also contain a video style chosen by the user such as Stunning Film, Blinds Effect, and Shining Life.
The WFSP file is the main file associated with Fantashow. The file is created when you save your project for the first time. When you are finished with your home movie you can burn it to a DVD or share it through email or to a social site directly from the application.
NOTE: Wondershare Fantashow has been discontinued.
