Note that source folders can only be currently used with Standard Make projects. Managed Make projects treat the entire project as a source folder.
Source folders are a way to cut down on a project’s indexing scope. You can mark the folders that are part of your day to day work or part of a subsystem that you work on. All files inside source folders will be indexed and are, thus, searchable. Note that any files pulled in by a file inside a source folder will also be indexed.
