To open a different project, use the Project > Open Project command (See also “Open Project”.) Source Insight only allows you to have one project open at a time, so if you already have a project open, it will ask you if you’re sure you want to close the current project. Assuming you do close the current project, the Open Project command will display a list box of existing projects from which to choose.
When a project is opened, the project’s configuration file and workspace file are loaded, which means the display, menu, and keystroke configuration may change and the files you had open in the previous session with the project are reopened.
When a project is opened, the current working directory is changed to the project’s source directory.
