New files are automatically added to the project if fAddNewFiles is True. Only file names that match document types defined in the Document Options command are added.
If fForceAll, then each file in the project is re-synchronized, regardless of its time stamp.
If fSuppressWarnings, then Source Insight will not issue warnings if it has errors opening files.
