Microsoft FrontPage Command Bars

In FrontPage, you can create custom command bars that will be available in the FrontPage workspace. In other words, custom command bars are generally available and are not linked to a specific FrontPage-based web. FrontPage command bars are saved in a file named CmdUI.PRF. If user profiles have been set up for multiple users, CmdUI.PRF is stored in the C:\Windows\Profiles\UserName\Application Data\Microsoft\FrontPage\State subfolder. If user profiles have not been set up, CmdUI.PRF is stored in the C:\Windows\Application Data\Microsoft\FrontPage\State subfolder.
