Source Insight is built around projects. A project is a collection of source files. When you create a project, you add files to it. Source Insight records what files are in the project by keeping a simple file database for the project.
As you create new files, they can be added to your project when you save them. If new files appear in your project directory or subdirectories, they can also be added automatically to your project by running the Synchronize Files command.
The Add File dialog box lists files and contains an Add button and an All button. For most projects, turn on the "Subdirs Also" checkbox and press the All button. This will add all files in the project's root directory and all subdirectories, recursively.
