Dragon help file lacking information.

To create a new user profile in Comodo Dragon
Quote from help file,

Please note that some of the old profile might be corrupted and may result in corrupting the new default folder also. If you want the old bookmarks, copy the file Bookmarks.bak' from the backup folder and paste it into the new 'Default' folder.
It fails to state that the [b].bak[/b] file extension needs to be removed for the [b]Bookmarks.bak [/b]file to come into use.
