When you choose Project > Display Statistics..., a dialog appears asking what type of statistics (Symbol table and/or File Type) you would like to see. When you have selected the type of project statistics, the Display Statistics dialog appears and shows the appropriate statistics for the projects checkmarked in the Project Tree.
Statistics are given for each checkmarked project in the Project Editor. In the Display Statistics dialog, you first see statistics for the different types of the Symbol table information (number of files in the project, number of includes, etc.).
The Symbol table statistics are followed by the File Type statistics for each checkmarked project. You can also see whether SNiFF+ automatically adds/removes files of a particular file type in the Add/Remove Automatically field. A Symbol table Statistics total and a File Type Statistics total for all checkmarked projects are then given at the bottom of the Display Statistics dialog. Please refer to Preferences, File Types view for a description of the Add/Remove Automatically attribute of a file type.
