Websites you create in iWeb are stored in one file, called “Domain,” on your computer.
You can copy this file to another computer as a backup or to work on your site from another location. For example, you may want to be able to update your website from home and from work.
The Domain file is located in the Library/Application Support/iWeb/ folder in your home folder.
Copy the Domain file to the default location shown above on another computer, and then open iWeb on that computer.
Copy the Domain file to another computer, but not to the default location, and then double-click the Domain file. iWeb opens.
In either case, the next time you open iWeb, the most recent Domain file opens.
Important:If you use the same Domain file on different computers, be sure to always use the latest version of the file. Otherwise, when you publish, you may overwrite your site with old information.
iWeb 2.0 can’t read domain files created in iWeb 3.0.
