You can customize Dreamweaver to suit your needs even in a multiuser operating system such as Windows XP or Mac OS X.

Dreamweaver prevents any user’s customized configuration from affecting any other user’s customized configuration. To accomplish this goal, the first time you run Dreamweaver in one of the multiuser operating systems that it recognizes, the application creates copies of a variety of configuration files. These user configuration files are stored in a folder that belongs to you.

For example, in Windows XP, they’re stored in C:\Documents and Settings\username\Application Data\Adobe\Dreamweaver 9\Configuration (which may be inside a hidden folder).

In Windows Vista, they’re stored in C:\Users\username\Application Data\Adobe\Dreamweaver 9\Configuration (which may be inside a hidden folder).

In Mac OS X, they’re stored inside your Home folder; specifically, in Users/username/Library/Application Support/Adobe/Dreamweaver 9/Configuration.

If you reinstall or upgrade Dreamweaver, Dreamweaver automatically makes backup copies of existing user configuration files, so if you customized those files by hand, you still have access to the changes you made.
