 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.
