About user configuration files

Fireworks creates a different set of configuration files for each user. The files are stored in the Adobe/Fireworks CS4 folder in your user-specific Application Data folder (Windows) or Application Support folder (Mac OS). The location of this folder varies depending on what operating system you use and whether you have a multiuser or single-user system. For information on locating this folder, see your operating system documentation.

Note: The names of some system folders may vary on localized and customized systems.
