Folders preferences
The folders preferences give you access to additional Photoshop plug-ins, texture files, and pattern files from external sources.
Additional Materials (Photoshop Plug-Ins, Textures, and Patterns) targets folders containing plug-ins, textures, and patterns. The folders can be in another folder on your hard disk, on a CD-ROM or other external drive, or on a network volume.
Photoshop plug-ins appear in the Fireworks Filters menu and the Property inspector's Add Effects menu. Textures or patterns stored as PNG, JPEG, and GIF files appear as options in the Pattern and Texture pop-up menus in the Property inspector.
For more information about textures and patterns, see Adding texture to a fill.
