Command-line parameters-
CCleaner .INI files-
CCleaner uses internally-stored settings (.INI) files to
determine which Windows settings and installed applications to
clean, and how to clean them. You can modify these .INI files by
creating replacement external ones and placing them in CCleaner's
installation folder. .INI files are in plain text, so you can edit
them with Notepad or manipulate them with scripting programs.
