Presetting Stroke, Fill, Effect and View
Note that although you can preset the Stroke, Fill, Effect and View menu settings, you won't be able to preset other settings such as slices.

Creating a Fireworks defaults file
1

Launch Fireworks and choose File > New to set up a new document. Set the new document to the size and dimensions which you will use for the files that will share the default settings.
2

Set the Stroke, Fill, Effect and View menu settings to be used in all of the files.
3 Choose File > Save As to save the file. This will open the Save dialog box.
4

Name the file:

Fireworks Defaults.PNG
5

Save this file in a Presets folder, as follows:
> Fireworks 2 or 3
In the Save dialog box, click on the New Folder Icon to create a new folder in the Fireworks > Settings folder. Name this new folder Presets.
> Fireworks 4
The Presets folder already exists in the Fireworks 4/ Configuration folder.
>

Fireworks MX
The Presets folder already exists in the Application Data (Windows) or the per user Application Support (Macintosh) folder under Macromedia/Fireworks MX folder.
6 Quit Fireworks and relaunch the program. This allows Fireworks to load these new presets.
7 Create a new document by choosing File > New. Strokes, Fills, Effects and the View menu settings are already set to your liking in the new document.
