A JSF file is a script command file created by Fireworks, a graphics editor application. It contains JavaScript code commands that perform certain actions in Fireworks, such as converting a shape color to gray or resizing a shape.

To create a JSF file: Perform a set of tasks on your stage, for e.g., create a circle and fill in the circle with a color. Select those steps in the "History" pane (most likely in the top-right). Click the floppy disk icon to save the steps and name your command. Verify that your command was created by selecting Commands from the menu, your command should appear at the bottom. For Mac users, JSF files are stored in the following directory: Macintosh HD > Applications > Adobe Fireworks > Configuration > Commands or Command Panels For Windows Users, JSF files are stored in the following directory: C:Program Files\Adobe Fireworks\Configuration\Commands or Command Panels NOTE: Adobe ceased development of Fireworks in May 2013, but it is still available in Creative Cloud as the Creative Suite 6 version.
